Funzi Island is known for its pristine beaches and as Kenya's best nesting site for a variety of sea turtles, such as green turtle, Chelonia mydas, hawksbill, Eretmochelys imbricata and leatherback, Dermochelys coriacea.

However, the turtles are becoming increasingly threatened in Funzi due to the expansion of non-environmental tourism and a heavy pressure from destructive fishing methods and various pollution sources.

Popular excursions for visitors in Funzi are the crocodile safari in the nearby Ramisi River or to going on a cultural tour in the village and enjoy a traditionally cooked lunch.

The best swimming experience in the area will undoubtedly be on the naturally formed sandbank just offshore from Funzi village.

A locally formed group called Funzi Turtle Club has started an ecotourism project with the support of Kenya Sea Turtle Conservation Trust to increase the protection and awareness about the local environment.
