The boat slips away from Diani’s coral-lined shore and the ocean unrolls into a flat, blue plain. Glass panels beneath the deck open a clear window into the Indian Ocean; schools of chromatic reef fish drift through sunlit channels while the silhouette of Robinson Island rises and falls with the tide. On low tides the island appears as a pale crescent of sand and rock, inviting short walks and shallow snorkeling; at higher tides it shrinks to a reef crowned by seabirds.

Check tide times
Robinson Island’s sandbanks and the best shallow snorkeling are tide-dependent — low tide reveals more walkable sand and clearer pools.
