For those in search of a place almost entirely untouched by humans, and still relatively unexplored, the Indonesian archipelago of Raja Ampat is well worth the trip. Located in the Coral Triangle, this is the world’s most biodiverse marine habitat; a pristine haven offering some of the best diving experiences on earth. With more than 1,500 islets surrounding 4 main islands, Raja Ampat is home to many species that are wholly indigenous, as well as three quarters of the world’s coral varieties. While there are many ‘bucket list’ dives in this area, the waters around the southern island of Misool are a highlight. Here, the gin clear sea means that you theoretically don’t even need to leave the yacht to see what is below the surface – but it would be a shame not to. Exploring Misool’s many caves, tunnels and channels you’ll see colourful corals and a dizzying array of sparkling reef fish as well as whale sharks, reef sharks, mobula rays, Napoleon wrasse and pygmy seahorses.
