Humpback whales may also pass through Zanzibar waters during their migration period, offering a rare and unforgettable experience.

What to Expect on a Diving Day

A typical scuba diving day in Zanzibar is well organized and designed to be smooth and enjoyable from start to finish.

Your day usually begins with a pick-up from your hotel, followed by a short transfer to the dive center where you will meet your instructor and prepare for the trip. At the dive center, you will receive a detailed briefing about the dive plan and go through an equipment check to make sure everything fits and works properly.

After that, you will take a boat ride to the dive site, which can take some time depending on the location. Once you arrive, you will begin your first dive, which typically lasts between 30 to 45 minutes. After the first dive, there is a surface break where you can relax, drink water, and prepare for the next dive.

The second dive follows after the break, giving you another chance to explore the underwater world. After completing the dives, you will return to the dive center and then be transferred back to your hotel, where you can relax and enjoy the rest of your day.

What to Bring

When preparing for scuba diving in Zanzibar, you only need a few personal items because most diving equipment is provided by the dive center.

You should bring swimwear since you will wear it under your diving suit or directly during warm-water dives. A towel is also important for drying off after your dive. Sunscreen is recommended to protect your skin before and after diving, especially when you are on the boat. Sunglasses are useful for protecting your eyes from strong sunlight during boat transfers.

If you enjoy taking photos, you can bring a waterproof camera to capture your underwater experience, although this is optional. Most dive centers already provide all essential scuba equipment, including wetsuits, masks, fins, and tanks, so you do not need to worry about bringing heavy gear.
