Top 8 most visited islands on Africa’s Indian Ocean coast

The Indian Ocean isn’t only about the Maldives. Along Africa’s eastern rim you’ll find islands that fuse Swahili, Arab and European history with landscapes straight off a screensaver. Here’s your 2025 insider guide to the region’s most‑visited islands and what sets each one apart. Pack your sense of humour and be ready to hop between dhow‑whispered harbours, spice farms and marine‑park coral gardens.

1. Zanzibar (Unguja), Tanzania

Vibe: Swahili‑Arab romance meets beach‑party energy. After a Serengeti safari, this is where travellers come to decompress and dance.

What makes it special: Unguja (commonly called Zanzibar) has done more for East African tourism than any other island. Stone Town’s labyrinthine alleys and ornate, brass‑stud doors testify to centuries of Arab, Persian and European trading. The World Heritage‑listed quarter exudes a melting‑pot culture that Travel Noire’s 2025 jury praised for blending Arab, Swahili, Indian and European influences.

On the coast you’ll find powder‑white beaches perfect for swimming or kitesurfing and a spectrum of accommodations, from breezy bungalows to flashy resorts. Tourism accounts for about 30 % of the region’s GDP and recent investments in hotels and infrastructure mean the island welcomes ever‑growing numbers of visitors so come soon before your secret becomes everyone’s.

The island is easy to reach via Zanzibar City’s international airport. Stone Town’s narrow lanes are made for wandering; pack modest clothing to respect the local Muslim culture. For the full spice experience, join a tour of a clove farm and finish with sundowners at a beach bar.
