The final pearl in the tropical beach necklace that stretches south of Mombasa is the idyllic island of Wasini, located about 76km south of the Likoni ferry crossing. With its faded white alleyways, Swahili fishing vibe and fat, mottled trees, this tiny island (it's only 5km long) feels like a distant relative of Lamu and Zanzibar. It's ripe with the ingredients required for a perfect backpacker beachside hideaway: it has that sit-under-a-mango-tree-and-do-nothing-all-day vibe, a coastline licked with pockets of white sand and Kisite Marine National Park, the most gorgeous snorkelling reef on the coast. In fact, the only things it doesn’t have are regular electricity, banana-pancake traveller cafes, backpacker hostels and cars, and it’s all the better for it.
