Seeing bioluminescent plankton in Zanzibar is a breathtaking experience, where the ocean glows with shimmering blue light at night. This natural phenomenon occurs due to microscopic plankton emitting light when disturbed by movement in the water.

Where & When to See Bioluminescent Plankton in Zanzibar

Best Locations:

• Paje Beach – One of the most popular spots on the east coast, especially near low tide.
• Jambiani Beach – A quieter location with fewer crowds.
• Michamvi Peninsula – Offers secluded night tours.
• Menai Bay (Fumba area) – Known for its conservation area and marine life.

Best Time to Visit:

• New Moon Nights (or nights with minimal moonlight) – Darkness enhances visibility.
• Warm & Calm Waters – Usually seen year-round, but clearer in dry months (June–October, December–March).

How to Experience It

Boat Tours & Night Swimming – Guided tours take you into deeper waters for a more intense glow.
Kayaking & Stand-Up Paddleboarding – Paddle through glowing water for a surreal experience.
Beach Walks – Sometimes visible in shallow waters, especially when waves crash against the shore.

• Wear swimwear if you plan to swim in the glowing water.
