Named after the spit of sand exposed by low tide, Sand Island consists of 10 spacious, airy, self-catering cottages overlooking the sand. Each has its own style – Pweza cottage, for example, features furniture made from salvaged Swahili doors – and all have colourful quilts and shady terraces. It's signposted from the main Tiwi Beach road and lies 3.5km along a dirt track.
You can hire your own cook for KSh800 per day and there are reef shoes and snorkelling masks for rent.
