There are plenty of water-based activities on offer at Watamu, including diving, deep-sea fishing and windsurfing.
Ocean Sports organises two-hour snorkelling outings in glass-bottomed boats to the coral gardens of the Watamu Marine National Park for around US$40 per person, with equipment provided, and another snorkelling stop in Mida Creek at high tide. Watamu Treehouse arranges more innovative snorkelling outings, with stand up paddle boarding to one or two of the best snorkelling sites.
Kayaking & Stand Up Paddle Boarding
If you're after straight-up gear rental, Tribe has SUPs for hire, while Ocean Sports rents sea kayaks. However, if you're looking for a guided kayaking or SUP trip into the Mida Creek mangroves or in the Watamu Marine National Park, Watamu Treehouse organises highly recommended trips for guests and nonguests alike.
Nonguests are welcome to attend yoga sessions at the Watamu Treehouse.
Watamu is one of the top diving destinations along the Kenyan coast, with 16 main sites to choose from and a good mix of reef and wreck diving. Diving is best between October and March, when the visibility is optimal and seas are calmest. Aqua Ventures runs highly professional diving trips to the likes of Moray Reef, famous for its giant eel, and Drummers' Reef, with its sea turtles, rays and shoals of Napoleon wrasse. Diving fees do not include the daily marine park fee of US$20.
