Bike 12 1/2 miles into Cotopaxi National Park, and then post signs that tout leave-no-trace ethics and warn against illegal hunting. Or go ziplining through the canopy at Hacienda Santa Rita Ecological Reserve and help with trail maintenance. This five-day Ecuador trip, run by Montana-based Adventure Life, blends adventure experiences with volunteer conservation efforts. You start with a horseback ride among herds of wild horses to the foothills of Rumiñahui Volcano, led by guides who will tell you about the area and its medicinal plants. Then spend three nights at the Hacienda El Porvenir, around which you will plant trees as part of a reforestation initiative. Rates start at $930 per person. 800-344-6118, www.adventurelife.com
