Safari Blue is the classic full-day dhow excursion in Zanzibar, and it earns its reputation. The day runs from Fumba on the south-west coast, out into the Menai Bay Conservation Area, on a traditional wooden dhow with a local crew.
The first stop is the reef, where snorkelling gear is handed out and you spend an hour over live coral and shoals of reef fish. From there the dhow sails on to a mangrove lagoon of extraordinary colour, then to a sandbank that surfaces as the tide drops.
Lunch is served on an uninhabited island: a seafood barbecue with grilled fish, calamari, rice, salads and a spread of tropical fruit, eaten under the palms. The afternoon is free to swim, walk the shoreline or sit in the shade. On the sail home the crew raise the sail properly, and if conditions allow the day finishes with the sun going down over the water.
The day is long, roughly eight hours door to door, and it is the single best value excursion on the island for anyone who wants sea, food and sailing in one trip.
