Unguja is the principal island of the Zanzibar archipelago (commonly called Zanzibar Island) and contains the territory’s main city and tourist zones. It blends coastal beaches, spice plantations and a historic urban core famous for its Swahili architecture.

The island’s most visited area is Stone Town, the old trading port and historic centre with winding streets, carved doors and mosques; Stone Town is a UNESCO World Heritage site. Outside the town, beaches, marine parks and resort areas along the west and north coasts are major tourism draws.

Unguja has long-standing cultural and trading links to the Swahili coast, the Arabian Peninsula and Indian Ocean commerce; the island developed as a regional trading and cultural centre over centuries.

Unguja lies off Tanzania’s mainland in the Indian Ocean; the main ferry and airport connections link the island to Dar es Salaam and other regional hubs.

How to Get to Unguja #

Tips for Visiting Unguja #

  • From the ferry terminal in Playa del Carmen take the 35-45 minute high-speed ferry to San Miguel, Cozumel.
  • Rent a scooter to explore the island's less-visited north and east coasts-many reefs and cenotes are past the main tourist strip.
  • Book advanced snorkeling or wreck-diving trips; Cozumel's reefs are protected and sometimes capped for limited numbers.
