Jozani forest and the mangrove boardwalk

Red colobus monkeys, mahogany and a six-hour hike into Zanzibar's only national park. Jozani–Chwaka Bay National Park is Zanzibar's only national park and home to the endemic Zanzibar red colobus, which you'll meet up close. The usual visit is an hour's gentle walk, but the park also runs a two- to three-hour middle tour, an early-morning bird walk and a six- to seven-hour long hike deep into the forest, with Sykes's monkeys, chameleons, bushbabies and elephant shrews. A short drive south, the Pete mangrove boardwalk crosses the swamp, with mudskippers and crabs at the right tide. How to book: Go with an official park guide from the gate, or book the long, middle or bird tours ahead through jozaniforest.com. It's about 40 minutes from Stone Town and 20–25 minutes from Paje by taxi; the dala-dala to Makunduchi or Paje stops at the gate.
