Trekking in the Cusco Region

Trek: THE INKA TRAIL (4 days, 3 nights)
Highest Altitude: 4198 meter
Difficult: moderate
Description: South America's most famous trek. The trail end is at "KM 82", follows an old Inca trail with several important Inca ruins and ends at the site of Machu Picchu. From there we take the bus to Agua Calientes (who feels like walking more: 1 hour downhill walking) and from there the train back to Cusco.
(Km 82 - Llulluchupampa - Pacamayo - Phuyupatamarca - Machu Picchu)
Reservations: Due to a very high number of visitors the amount of people entering the trail is now limited to 500 per day (still very high: impossible to avoid the hand-in-hand walking feeling). In the high season therefor, reservations have to be made at least 6 weeks in advance to assure your place. In the low season reservations may be made up until 2 weeks before starting the trek.
It is not allowed to hike the Inca Trail without official guidance.

Trek: Inca Trail Alternative: Mollepata to Machu Picchu (5 days, 4 nights)
Highest Altitude: 4700 meter
Difficult: moderate
This trail runs higher and closer to the snow-covered mountains and is not so highly frequented as the Inca Trail itself. There are hardly any tourists here and you'll have a lot more contact to the locals and rural villages. There are no ruins on the trail but obviously we visit Machu Picchu after finishing the trek. Many people prefer this trek to get away from the crowds on the Inca Trail, especially those who don't necessarily need to see all Inca ruins.
(Mollepata - Cruz Pata - Soraypampa - Huayracpunko - Colcapampa - La Playa - Llactapata - Machu Picchu)

Trek: Choquequirao ("newly discovered Machu Picchu") & Machu Picchu (8 days, 7 nights)
Highest Altitude: 4700 meter
Difficult: difficult
The Choquequirao ruins are a fairly bit smaller than Machu Picchu but also in a spectacular location and so far(!) hardly visited. From Choquequirao we continue the trek to Machu Picchu itself.
(Cachora - Cerro Rumihuasi - Rio Apurimac - Santa Theresa Valley - Machu Picchu).

Ausengate Trek: (6 days, 5 nights)
Highest Altitude: 5165 meter
Difficult: moderate
Often forgotten but very beautiful trek around the Ausengate vulcano in the Cordillera Vilcanota. Because of the distance to Cusco and very few visitors, villages are very much how they were centuries ago. There is no electricity and most locals speak Quechua only.
