About Mnemba Marine Conservation Area

 

Established in 1995, the Mnemba Marine Conservation Area protects a coral atoll ecosystem about 3 kilometers offshore from Zanzibar’s mainland. The reserve covers approximately 8 square kilometers and encircles Mnemba Island, which is surrounded by vibrant coral reefs hosting a diverse range of marine species. The area encompasses shallow lagoons, fringing reefs, and deeper outer reef slopes, creating critical habitat for sea turtles, dolphins, reef fish, and numerous invertebrates. As one of the premier eco-tourism destinations in East Africa, Mnemba attracts snorkelers and scuba divers eager to explore its clear waters and healthy reefs. The conservation area is managed through a community-based approach focusing on sustainable fishing practices and environmental education to safeguard the fragile ecosystem. Visitors can enjoy guided snorkeling and diving excursions with expert operators who highlight key underwater features such as colorful coral gardens, reef sharks, and seasonal manta ray sightings. While the island itself hosts a luxury private lodge with restricted access, day trips and tours from Zanzibar’s main island allow public appreciation of the marine environment. Mnemba’s pristine conditions and abundant marine life make it a must-visit for wildlife enthusiasts and conservation supporters. Its proximity to Zanzibar town and accessibility by boat provide convenient entry points, further enhancing its appeal.
