Vamizi Island, one of andBeyond’s three eco resorts off the north coast of Mozambique, east Africa, is the destination for two guide-led trips in 2019 (March 14-19 and October 9-14). The island lies at the heart of one of the world’s healthiest coral reefs, with 180 species of coral and 400 species of reef fish. Accompanied by Dr Tessa Hempson, a leading marine biologist, guests will gain unparalleled insights into the ecology of the island, joining in conservation work such as measuring reef systems. There will be kayaking opportunities and, for the experienced, a trip to Neptune’s Arm, a submarine plateau legendary among divers. A five-night stay in one of six private villas costs $10,775, including a $1,500 donation to andBeyond and Africa Foundation’s Oceans Without Borders conservation programme in east Africa.
