Trekking specialist company World Expeditions has launched six new itineraries with a cause. The Rebuild Nepal Community Projects include an adventure trek at various sites along the Nepalese mountains, as well as the rebuilding of damaged schools during the recent Nepal earthquake.

The first project departs Oct 12 and is a 26-day affair with five days for community building at Lura School and 16 days of trekking around the Everest base camp. The last trip departs Jan 10, 2016 and is a 21-day trip covering 10 days of community building and six days of rafting, a safari experience and tours around Kathmandu's Pokhara Chitwan. And don't worry, you don't need prior building experience to participate. Treks start at $2,587 per person, inclusive of meals, a trek pack and flights from Kathmandu, Phaplu and Lukla.
