Salkantay Trek to Machupicchu 5 days / 4 nights - Private Service
This amazing trek runs beneath the sacred Salkantay mountain (6.271m/20569ft), one of the highest and most stunning in the Peruvian Andes, passing through Quechua communities and lesser-known Inca ruins, to finally reach Aguas Calientes on the fourth day. The impressive Sacred Inca city of Machupicchu is visited on the last day of the program. This itinerary is an interesting alternative for those not having found spaces on the Inca Trail trek to Machupicchu.
Day 1 Cusco to Soyroccocha
We leave Cusco at 05.00 am in a private transportation and start a scenic morning scenic bus-ride to our trail starting point at Challacancha. Along the four-hour drive, we cross the town of Limatambo (2100m/6888ft), an important point of access to the city of Cusco during the time of the Inca Empire. We leave Limatambo and drive up a beaten track along the right shore of the Apurimac River, to reach Mollepata (2800m/9184ft), then Cruzpata (3100m/10168ft) and finally Challacancha, where we meet our wranglers and horses. After a short introduction we start our hike, following the paths of the locals on a soft ascent towards the base of Mt. Salkantay (6271m/20569ft). After lunch in Salkantaypampa, we start our sometimes steep 2 hrs ascent to our camp at Soyroccocha, just next to the impressive glacier of Salkantay (4200m/13776ft). This will be a cold night so very warm clothes are essential.

Day 2 Soyroccocha to Collpapampa
We depart early after breakfast and start a 1,5-hour ascent, which brings us up to the Salkantay Mountain Pass (4525m/14842ft) where, besides enjoying stunning views of the surrounding glaciers and the snow-capped peaks of the Vilcabamba Range with the south face of Salkantay towering above us, we may also observe chinchillas and condors in their natural habitat. From this point, we start descending towards a more tropical climate and into the so-called cloud forest. Along the route, we can see the remains of an ancient Inca path, which is approximately 6 meters wide. A long though easy descent along the Salkantay River, brings us late afternoon to our second camp at Qollpapampa (2890m/9479ft), a beautiful spot with some natural hot springs to relax in.

Day 3 Collpapampa to Lucmabamba
Today we continue our hike with an easy walk along the Santa Teresa River, enjoying the increasingly lush vegetation, passing waterfalls, passion fruit and coffee plantations. We pass the waterfalls at Coripacchi, the settlement at Wiñaypoko, the bustling small town of La Playa and finally our third camp at Lucmabamba (2,100m/6888ft). On the way we can see plantations of banana, coffee, and avocado, as well as exuberant local flora. We enter spectacled-bear territory and we will probably be accompanied by flocks of parrots as we descend. At dinner we can enjoy a cup of coffee.

Day 4 La Playa – Aguas Calientes
After breakfast, we start climbing for 2-3 hours up to El Mirador or Abra Q'elloqasa (2860m/9381ft) from where we have an exceptional view of the Lost City of the Incas, the legendary Machupicchu, from a different angle. We enjoy a last lunch in nature at the lookout point of Llaqtapata (2650m/8692ft) from where we can view both Machupicchu and the Salkantay Mountain and take a good rest, enjoying the added value of the Llactapata Ruins, which have recently been restored. A 2-hour descent towards the Aobamba River crossing lush bamboo forests and more orchards and coffee plantations brings us to the hydroelectric plant of Machupicchu from where we board a train that takes us to Aguas Calientes (short, scenic 40-minutes train ride). Accommodation at the chosen hotel.

Day 5 Aguas Calientes / Machupicchu to Cusco
We wake up early and board a bus to Machupicchu where we begin a complete guided tour of the Inca citadel that will take approximately two hours. You will then have free time to walk around, climb up the Huaynapicchu Mountain, where one can experience spectacular views of all of Machupicchu, the valleys and mountains that surround it (please note that there are only 400 visitors allowed per day), or visit the Temple of the Moon or the impressive Inca Bridge(***).

From here we take the train back to the city of Cusco, where we arrive after nightfall.

We recommend massage sessions before and after your trekking program. Services are at the hotel and are only available in Cusco.
- Appropriate clothing along this hike
Hiking pants and T-shirts are recommended during the day, complemented by sweaters, fleeces and waterproof jackets. It is very convenient to have light raingear available in the daypack (rain poncho or jacket and/or rain pants) as the weather changes easily and rains can suddenly occur. At night, warm clothing is required, down jackets can be useful, otherwise a fleece and a jacket. During the fourth day (if sunny) and in Machupicchu, convertible hiking pants are useful, as can be switched into shorts if necessary. Machupicchu has a warm climate, getting only cold at night. The rest of necessary implements are included in the “What we recommend that you bring” list.
Cusco’s climate is divided into two differentiated seasons: the rainy season, from November to April (the heaviest rainfalls occurring usually between January – March); and the dry season, from May to October. The dry season is colder, so temperatures can drop to below 0 degrees at night.
Along the Salkantay route, temperatures range from 10-20ºC during the day if it’s sunny, to 05-10ºC during the day if not sunny and can drop below freezing at night. In Aguas Calientes/Machupicchu, at lower altitude, temperatures are usually warmer though warm clothes are still recommended at night.
- Why choose ENIGMA
- Because all our treks are only and strictly operated by Enigma and its very professional staff. Other agents claiming daily departures operate their treks jointly with other companies in service rotation. Hence, you book a departure with tour operator A, which risks to be finally operated by tour operator B without you knowing. ENIGMA has a quality of service and a high reputation, which is only possible by ensuring that only ENIGMA staff operates ENIGMA treks. Even if we only have a single traveler for a set departure date, this will be operated by us.
- Because we have and can prove an excellent treatment to our staff, including chefs, porters and wranglers. ENIGMA not only complies with the Porter Law and Regulation, but our wages are over the minimum requested by law and above the average paid by most of the tour operators, all our staff eats well and more than enough, they are provided with sleeping bags, thermal clothes, sleeping tents, trekking boots, thick rain ponchos, harnesses and lumbar support for their duty on field. Most importantly, they have a program ensuring them a minimum number of departures per month and hence, a minimum income per month as well.
- Because we are very careful to choose the best guides for each group. About 80% of our guides work exclusively for ENIGMA and are highly trained, have excellent language proficiency and communication skills and are regularly evaluated by the service reports each guest fills in after each service. We have special guides for special requests (ornithology, history and archaeology, flora and fauna and also generalist guides). All our guides have been trained in advanced first aid by the Sierra Nevada Outdoor Education / Wilderness USA. We also have guides proficient in several languages besides English and Spanish, including French, Italian, German, Chinese and Japanese. In all of our treks, not only on the Inca Trail, there will be a guide for every 8 guests with one of them being the head guide. This ensures a higher safety and attention to guests versus other operators.
- Because we have one of the best equipment in field, renewed every year, employing excellent brand and performance tents, surgical steel vaiselle for best hygiene, best water filters, therm-a-rest inflatable sleeping pads, orthopaedical foamy three-level sleeping pads, among others.
- Because we have one of the best meal services in field in the area: our chefs have been trained by several institutes in Lima, Cusco and also by chefs coming from the NY Culinary Institute. They have learned the HACCP method and their operation ensures maximum hygiene. Above all, be prepared to not only have a superb trekking experience but also a culinary one, including generous and delicious breakfasts, snacks, lunches, tea services and dinners that we can adapt to your very specific requests. Our menus include a variety of Peruvian and international food and also cater for vegetarian, vegan and special dietary requests (Atkins, Gluten-free, etc), all at no extra cost. ENIGMA is recognized for its gourmet meals, the quantity and quality of food, as well as for its outstanding menu design. This is another factor for a higher price as we take natural ingredients on the treks and prepare them in the field, we do not take prepared low quality food, the meals being an added experience in all of our programs.
- Because ENIGMA’s responsible operation makes sure to cause a low impact on the environment of the natural protected areas where it runs. We train all our staff in our environment policy and, for example, ENIGMA is so far the only Inca Trail Official Operator to run a yearly Inca Trail Clean-Up.
- Because we pay legal taxes (19% IGV or consumption tax) on all services contributing to the country’s growth and development. Further to this, we pay a 30% tax on all earnings. There are many tour operators who do not pay taxes and do not declare neither their sales nor most of their earnings, or declare them with a lower value, giving them this the possibility of lowering their prices through what to our eyes is an unloyal competition. Our policy will never be not to declare taxes.
- Because all of our Group Services have a maximum group size of 12, whereas most tour operators work with a maximum of 16 on the Inca Trail, since this is the authorized by law, or even higher on other routes. We have established 12 as a maximum since this increases the quality of our service, as there are definitely spots along the treks where being 16 makes it impossible to provide a personalized service and explanation.
- Also, our excellent treatment to our staff is not reduced in the low season: porter wages are maintained, same as guide fees, which is something highly appreciated by our staff, since some operators prefer to decrease prices and wages as they know the porters, guides and chefs do not have as many demand for work as in the high season. We have our own staff which is exclusive and do not like abusing in this way since, basically, the work they do and the quality of performance we demand has to be the same in the sunny or rainy season, whether you book ahead or in the last minute.
- Finally, because all in all and due to all of the above, we have very highly satisfied guests, as our numerous testimonials prove. In our Testimonials section of our website you may find reports dating from 2003 (when we started our operation) to today. The original reports are available at our office in Cusco.
We are aware other operators may offer the Inca Trail or other programs at a lower price. This does not mean they are offering the same program at a lower price: the level of service will not be the same. We understand price is definitely an issue but we kindly request our potential guests and clients to choose a responsible tour operator as otherwise, you risk to be indirectly promoting the exploitation of rural communities and the growth of informal and illegal operators that do not build on the country’s development and growth.

Please note that travel arrangements are not confirmed until stated so in writing by ENIGMA.
Payment / Deposit
An appropriate deposit per person for the chosen program is requested at the moment of the booking. This deposit is non-refundable in case of cancellation by the client. The balance of the program has to be paid prior to departure in a date that will vary according to the program that you are booking and the indications that you will receive from your travel consultant.
Cancellation by Us
ENIGMA reserves the right to cancel a program in case any of the following circumstances occur:
Client’s failure to pay the due balance of 60 or 20 days (according the booked program) prior to the departure date. In this case, the client will not have any right for the deposit refund.
Force majeure: Impossibility to operate the program due to unusual or unforeseen circumstances outside ENIGMA’s control. Ie. Delays in departures on travel arrangements caused by technical problems, weather conditions, over-booking or closure of a hotel, strikes, riots, decisions by State Governments or Tourist Organizations altering the itinerary, the duration of the time spent in a city or even omitting a city or part of the itinerary due to the local situation. In such cases, ENIGMA will propose viable solutions to operate the program or comparable travel arrangements. If any of the circumstances listed above occur during the course of the tour, we reserve the right to alter the scheduled itinerary accordingly and no compensation will be paid. We will make every reasonable effort to provide you with the booked program arrangements but changes may occur. If they are significant we shall, if possible, inform you before the departure date.
Again, we will offer comparable alternative arrangements. All additional expenses derived will be at the expense of the client. Please note that ENIGMA will not be liable to reimburse additional expenses undertaken by the client in preparation for the tour, this including international tickets, used mileage awards and fees, cost of visas, immunizations, shots, among others.
Alterations by You
If the client requests any amendments to the initial travel arrangements once a booking is confirmed, no amendment fee will be payable unless the program changes its nature significantly. Upon request of additional services such as train tickets, domestic airfare, etc., ENIGMA will charge an additional $30.00 for each solicited service. If due to the amendment, ENIGMA should have to assume significant communication charges or other expenses, these would be payable by the client. If amendments are requested after the commencement of the tour, ENIGMA will do its best to implement them, but we cannot guarantee that it will be possible. In the event of such an amendment being made, the client will be liable for any cancellation/retention charges that may be levied for the previously booked service and for any costs incurred by ENIGMA in attempting to secure any revised arrangement.
Cancellation by You
In case of cancellation by the client, this should be notified to ENIGMA in writing. Please note that the program deposit is non-refundable. Such notification will only be deemed to have been given on receipt of your letter or e-mail, since we can only act on receipt. Please state the reason for cancellation as you may be covered by your insurance policy.

Acceptance of Risk
Some of ENIGMA’s itineraries have been designed to provide participants with an exposure to the true nature of the environment visited. They therefore involve an element of personal risk and exposure to potential, which could result in physical or emotional injury, paralysis, death, or damage to the client, his/her property or to third parties. The client understands that such risks simply cannot be eliminated without jeopardizing the essential qualities of the activity and therefore assumes them as part of the tour. The client accepts that he/she is aware of his physical and health condition and that, under the knowledge of this he/she decides to undertake the abovementioned risks. The client excludes ENIGMA from any responsibility linked to any accident or injury that may occur associated to the clients’ health, physical condition or other.
Authority on Tour
At all times the decision of the company's guide or representative will be final on all matters likely to endanger the safety and well being of the tour group.
The client must at all times strictly comply with the laws, customs, and foreign exchange and drug regulations of Peru. Should the client fail to comply with the above, or should the client interfere with the well being of the group then the guide or company representative may order the client to leave the tour without recourse to any refund.
It is the responsibility of the individual traveler to secure the proper documentation prior to joining the program. The client must be in possession of a valid passport with at least six-month validity from the date of entry and all visas required for the whole of the journey. Any information or advice given by the company on visas, vaccinations, climate, clothing, baggage, special equipment, etc. is given in good faith but without responsibility on the part of the company.
The company shall not be liable for any damage or loss if the failure to carry out the contract is:
1. Attributable to the client
2. Attributable to a third party unconnected with the provision of the services contracted for and the event is unforeseeable or unavoidable
3. Due to unforeseen and unusual circumstances beyond the company's control, the consequences of which could not have been avoided even if all due care had to be exercised. The company will do its best to minimize the effects of matters outside its control, but cannot accept any liability for these matters which include political disputes, border closures, refusals of visas, industrial action, delayed flights, unforeseeable climate, strikes, war, civil disturbances, natural disasters, government actions, mechanical failures or any acts of God, among others. The client accepts to assume all extra costs derived by any of these factors.
ENIGMA directly operates part of the services included in a program but also makes arrangements with airlines, hotels and other independent parties to provide you with the travel services you purchase. We do take all reasonable steps to ensure that organizations providing services maintain our quality standards. However, these parties are independent suppliers over whom we have no direct full control.
ENIGMA can therefore not accept liability for negligence of the staff of these organizations. The participant waives any claim against ENIGMA for any damage to or loss of property, injury or death due to any act or negligence of any airlines, surface transportation company, hotels or any person rendering any of the services or accommodations included.
ENIGMA cannot be held responsible for any claim, losses, damages or delay of baggage or other properties, inconvenience, loss of enjoyment, upset and disappointment, distress or frustrations, whether physical or mental, resulting from the act or omission of any party providing the services. In the event of any service being withdrawn by any of our suppliers, ENIGMA shall have no responsibility beyond refunding all monies paid by the participant for that service.
When you travel with an airline, the conditions of carriage of that airline will apply. These conditions are the subject of international agreements and may limit or exclude liability. ENIGMA is not liable for any expenses or consequences resulting from flight delays, cancellations or missed connections, and such expenses shall be borne by the client.
Claims and Complaints
If a client has a complaint against the company the client must first inform the tour conductor, guide or company representative while on the tour in order that the guide/representative can attempt to rectify the matter. Any further complaint must be put in writing to the company within 7 days of the end of the tour.
Venue for all claims or disputes shall be exclusively in Cusco, Peru, whose courts, using Peruvian Law, shall have exclusive jurisdiction. Damage claims against ENIGMA shall be limited to the value of the particular item in dispute.
Any liability is limited to the full price paid for the tour. In all cases the company specifically excludes all liability for indirect, incidental or consequential loss or expense including loss of profits.
ENIGMA assumes responsibility for representations it makes, but not for those made by others and including, but not limited to, any employee of ENIGMA or any independent travel agent.
Payment for reservations on any ENIGMA program or tour shall constitute consent to all the provisions in the Booking Terms & Conditions set out herein and is binding on all tour and travel participants.
