Trekking in the Peruvian Andes

Welcome to our website! Lost City Treks is a small Peru-based company created by travelers like you. We do only a limited number of trips each year and we guide them ourselves. Our treks and educational adventures are designed to provide authentic encounters with the people, geography, history, nature, and food of the Andes.

Our educational/study abroad trips are all customized to focus on your specific needs. We look forward to traveling with you in this remarkable country.

Educational Adventures

We specialize in study abroad programs and other educationally oriented treks, tours, and homestays. We manage the logistics, which includes acquiring local expertise when needed, and build these trips around your interests. We can focus on history, archeology, sustainability, local culture, or biology and we can do them almost anywhere in Peru.


Los Cedros/Alpamayo/Santa Cruz Trek

This 8-day route is the longest and most remote of the established treks in the Cordillera Blanca. The scenery is varied and every bit as spectacular as the more popular routes and features a side trip to see the iconic north face of Alpamayo.
