Volunteer travel organiser GVI is offering a Belize Diving & Marine Conservation Internship. It would take you to the small tropical island of Ambergris Caye, near the Belize Barrier Reef (the world’s second-largest).
You’d train as a PADI pro diver and coral-reef researcher, carrying out underwater surveys and assisting with various conservation initiatives.
“The clear, warm Caribbean waters flourish with parrotfish, eagle rays, sea turtles and a vibrant array of corals,” says GVI, and the work aims to tackle threats from tourism, coral-bleaching, invasive species and pollution.
The programme costs from £3395pp for four weeks to £10,545 for 24 weeks, including training, accommodation, meals and as many dives as can be fitted in.
