Rutaki Drop Off - Rarotonga

Tanjung Sari, on the cusp of the channel, feels different from the usual Gili dives. We love starting on that gentle slope, around eight metres, where the light plays off the soft corals and those thick branching acropora colonies. It’s like swimming through a well-tended garden, but keep your eyes peeled for the schools of fusiliers – they can be so dense they momentarily dim the light around you. The real draw, for us, is when you drift towards the channel. The topography here gets interesting, shifting from slope to these almost canyon-like rock formations. We’ve spotted Blue-spotted Stingrays nestled on the sandy patches, and the resident Spotted Hawkfish always seems to be posing on a coral head. It’s also a good spot to catch an Olive Ridley or even a Leatherback Sea Turtle cruising past. The maximum depth of 19 metres makes it a comfortable dive for most, and with an average visibility of 16 metres, you get a good, clear view of the action. It suits divers who appreciate a bit more varied topography and enjoy a leisurely drift, keeping an eye out for larger pelagics in the blue.
