Thailand’s Surin province is home to more than 300 elephants, many of them treated inhumanely for street begging and circus performances. The harsh treatment these elephants endure can lower their life expectancy by at least 50%. On the “Thailand Elephants” trip, participants will be working at the region’s only "elephant refugee camp.” Volunteers’ tasks are dependent on the camp’s specific needs but could include the preservation of elephant habitat, the construction of shade shelters and enclosures, and the preparation of food for the elephants. This weeklong trip costs $905.
