Zanzibar Day Trips to Mnemba Island: Complete Snorkeling & Diving Guide
Planning a Mnemba Island day trip from Zanzibar? As someone who’s explored this pristine atoll multiple times, I can tell you it’s an absolute gem in the Indian Ocean. This comprehensive guide will walk you through everything you need to know about visiting this spectacular marine sanctuary, from the best snorkeling spots to insider tips that’ll make your journey unforgettable.
Quick Overview of Mnemba Island
Location and Geography
Nestled roughly 3 kilometres off the northeastern coast of Zanzibar, Mnemba Island is a private paradise surrounded by a stunning coral atoll. The island itself is small – you can walk around it in about 20 minutes – but the surrounding reef system spans an impressive area of nearly 4 square kilometres.
Best Time to Visit
The ideal time to visit Mnemba Island is during the dry seasons from June to October or December to March. I’ve found that July to September offers the most reliable weather conditions, with calm seas and excellent visibility for snorkeling and diving. Water temperatures hover around a comfortable 25-27°C (77-81°F) year-round.
Marine Life and Coral Reefs
The waters around Mnemba boast some of East Africa’s most diverse marine ecosystems. You’ll encounter vast coral gardens, tropical fish species, and if you’re lucky, dolphins, turtles, and even whale sharks during certain seasons. The reef’s pristine condition makes it a photographer’s paradise and a marine enthusiast’s dream.
Getting to Mnemba Island
Transportation Options from Zanzibar
The journey to Mnemba begins from either Nungwi or Matemwe beaches. Most visitors opt for organised tours that include boat transfers, but private charters are also available. I recommend booking through established operators who maintain reliable vessels and experienced crews.
Travel Duration and Cost Breakdown
The boat ride typically takes 20-45 minutes, depending on your departure point. Expect to pay between £60-100 per person for a standard day trip package, which usually includes transfers, equipment, and refreshments. Private charters can cost upwards of £200 but offer more flexibility and exclusivity.

Best Snorkeling Spots
The western side of the atoll offers the most accessible snorkeling sites, where crystal-clear waters reveal vibrant coral gardens. My favourite spot, locally known as ‘Coral Garden’, features shallow waters perfect for beginners while still offering plenty to excite experienced snorkelers.
Marine Species You’ll See
During my visits, I’ve encountered an incredible array of marine life, including:
- Green sea turtles and hawksbill turtles
- Bottlenose dolphins
- Various species of reef fish
- Occasional reef sharks
