14 Volunteer Vacations Where You Can Help Animals & Explore Amazing Places

13. Wildlife Rehabilitation – Borneo, Malaysia

Borneo’s rainforests are among the most biodiverse in the world—and they’re under threat. Volunteers here support orangutan conservation by preparing food, building enrichment tools, and helping with reforestation. You may monitor animal behavior or assist with release programs. Surrounded by dense jungle, the center operates with minimal impact and maximum care. You’ll fall asleep to insect symphonies and wake to gibbon calls. It’s sweaty, tough, and humbling—but each task directly supports survival for one of Earth’s most intelligent species.
