A trip to Machu Picchu, the stone-stacked “Lost City of the Incas” that towers 8,000 feet above sea level in Peru, is a once-in-a-lifetime experience within itself.

A 13-day tour that traverses Lima to Cuzco (with plenty of archeological site visits peppered throughout), coupled with a heavy dose of voluntourism, makes it truly unforgettable.

This year, the non-profit Planeterra Foundation is offering just that. The hands-on venture, launched in July of this year, is the latest community development project allowing travelers the opportunity to pitch in during their visit to the Sacred Valley. Dole out $1,820 per person (departures are available each month, year-round) and you can lend a hand constructing adobe stoves the Ccaccaccollo community—modeled with innovative piping that will lessen the high percentage of upper respiratory health problems and eye infections common to remote Andean village.

Early this month, the first smoke-free stoves were built for the extended project, including the training of 10 community members who will in turn, oversee the “Project Machu Picchu” construction.
