Nature tours and excursions in Zanzibar

The green and underground side of the island. Jozani Forest and its red colobus monkeys, the swimming caves at Maalum, Kuza, Salam and Fukuchani, the mangrove boardwalks, and the spice farms that gave Zanzibar its old name.
Jozani is the only place the Zanzibar red colobus lives, and the troop there is used to people, so you see them properly rather than as movement in a canopy. The caves are freshwater sinkholes: Maalum runs timed entry slots, while Fukuchani and Salam are quieter and take walk-ins.
These are the tours that work in any weather and at any state of the tide, which makes them the sensible choice for a day when the sea is rough.
