What is the best time of day to visit?

The dry seasons from June to October and January to February are the best times to go.
The island is accessible year-round. However, the dry months offer the best conditions for the 20-to-30-minute boat ride from Stone Town. Clear weather also improves visibility if you plan to snorkel at the surrounding reef.

You will need 20 to 30 minutes each way for the boat ride. On the island, plan for 30 to 45 minutes at the tortoise sanctuary and 30 minutes exploring the Historic Quarantine Station Ruins. Many visitors book a half-day package to cover these sites.
Do you need a guided tour to visit early?

You can negotiate directly with boat captains on the Stone Town beachfront for $15 to $30 USD per boat. Alternatively, you can book a guided tour. A tour often includes your island entry fee (about $12 USD) and snorkeling gear. Hire a Boat
Are the tortoises more active in the morning?
The tortoises are generally more comfortable before the peak midday heat.
When you arrive, you can buy approved leafy greens from the keepers to feed them. Do not feed them outside food. Remember that you cannot sit on, ride, or place heavy weight on the tortoises. Tortoise Rules
What should I pack for a morning departure?
Bring sun protection and waterproof shoes.
Even in the morning, the Zanzibar sun is strong. Pack reef-safe sunscreen, a wide-brimmed hat, and sunglasses. Wear waterproof shoes or sandals, as you will need to wade through shallow water to board your boat in Stone Town.
