South American Explorers

Now more than three decades old, the venerable South American Explorers Club is an indispensable resource for long-term travelers, journalists and scientists spending long periods in Peru, Ecuador, Bolivia and Argentina. It has an extensive library as well as a vast array of guides and maps for sale, including trail maps for the Inca Trail, Colca Canyon, Mt Ausangate, the Cordillera Blanca and Cordillera Huayhuash. You can also attend talks, get useful information on travel conditions in remote areas and research volunteer opportunities.

This member-supported, nonprofit organization helped launch the first clean-up of the Inca Trail and has supported local medicine drives. Annual dues are US$60 per person (US$90 per couple) or a US$30 membership is good for three months. There are additional clubhouses in Cuzco, Quito and Buenos Aires (find contact information online). You can sign up in person at one of the offices or via the website.

Members receive full use of the clubhouse and its facilities, including luggage storage, poste restante, a book exchange and discounts on items sold on-site. Members can also take advantage of the club's rooms for rent and get discounts at businesses throughout Peru. Members can look at their Lima Survival Kit, a helpful guide for new long-term residents.

Nonmembers are welcome to browse some of the information and purchase guides or maps.
