Zanzibar Island

Swimming is generally very safe, especially inside the coral reef that protects most beaches. The biggest thing to know is the tides - they're dramatic. At low tide, the water can recede several hundred meters, revealing the coral reef. High tide is best for swimming. Jellyfish aren't a major problem, but occasionally you'll find them. Watch out for sea urchins in rocky areas. Most beaches have local guides who'll advise you on conditions.

Yes, even though you're traveling within East Africa, you'll need a Tanzania visa. The good news is Kenyans and most visitors can get a visa on arrival at Zanzibar Airport or apply for an e-visa online before traveling. Make sure your passport is valid for at least 6 months. Some nationalities get free entry, so check current requirements before you fly.

It depends on what you're after. Stone Town is perfect for culture and history buffs who want to be in the heart of things. Nungwi and Kendwa in the north have minimal tides and great nightlife. The east coast (Paje, Jambiani) is ideal for kitesurfing and more laid-back vibes. South coast (Kizimkazi) is quieter and great for dolphin tours. If money's no object, private islands like Mnemba offer ultimate luxury and seclusion.

Taxis, hotel transfers, guided tours, rented scooters, or private drivers.
