Russell Islands - Iron Bottom Sound

The Russell Islands, just a short hop from Guadalcanal in Iron Bottom Sound, are a staple on most Solomon Islands itineraries, and for good reason. We always enjoy the sheer variety here. You'll spend mornings navigating sun-dappled channels and caverns, the light playing tricks on your eyes, then drift over current-swept pinnacles in the afternoon, keeping an eye out for bigger fish passing through. There are vibrant coral reefs that live up to the “Rainbow Reef” name, thick with fusiliers and anthias that swirl like a living kaleidoscope. And of course, being the Solomons, you'll find scattered WWII relics, a somber reminder of history beneath the waves. It’s a spot that offers a lot, from easy reef exploration to more dynamic drift dives, suitable for divers comfortable with a mix of conditions.
