Teach basic English and computer classes to children living in the remote mountain village of San Pedro de Casta, north of Lima. Those with carpentry skills can help with community housing repairs and build simple Lorena stoves. When the workday ends, hike or horseback ride to the majestic stone sculptures on the Markawasi Plateau.
Trip Tip: Take an Andean cooking lesson while you’re there. Pachamanca, a traditional dish of meat wrapped in banana leaves and cooked in a hot stone oven, is a must-try.
Luxury Level: Volunteers stay at the central village lodge with basic amenities. Those who tend to get the shivers should bring an extra blanket or two.
