13.Mnemba Dolphin and Snorkeling Tour

★★★★★★★★★★4.1 · 31 reviews · 6 hours · from $15Best value

From Nungwi, you take a dhow or speedboat toward Mnemba Atoll for dolphin watching and guided snorkeling over coral reefs. Expect about six hours, refreshments, equipment, and optional hotel pickup. The island itself is private, so the tour stays on the water. Dolphin encounters are not guaranteed, and boat traffic can be heavy.

“This Mnemba Dolphin and Snorkeling Tour was absolutely amazing from start to finish! The team was super friendly, professional, and made sure everyone felt safe and comfortable. We started the morning with a scenic boat ride over crystal-clear turquoise waters — and seeing the dolphins swimming freely beside the boat was pure magic! 🐬✨ After the dolphin encounter, we went snorkeling around Mnemba Atoll, and the underwater world was breathtaking — colorful coral reefs, schools of tropical fish, and even a few sea turtles! The guides were patient, helpful, and showed us the best spots. It was truly one of the best experiences in Zanzibar — relaxing, exciting, and full…”

14.Tumbatu Island Private Snorkeling Adventure Tour

★★★★★★★★★★4.0 · 26 reviews · 3.5 - 5.5 hours · from $78

Travel from northern Zanzibar to Tumbatu and nearby reefs for a private snorkeling trip with guides such as Hasan or Ali. Expect clear water, fruit, soft drinks, and a quiet setting with few boats. Reef quality can vary, and low tide may mean a muddy walk to the boat, so bring reef shoes.

“We had a wonderful snorkeling adventure with Hasan and the captain of the boat. We were the only boat in the area where we snorkeled off of Tumbatu island. For the budget price, we thought it was a good value without luxury but we had all we needed. I recommend it for a more local style adventure.”

Per lo snorkeling abbiamo avuto paura di tuffarci causa avvistamento di un banco di meduse. Mi dispiace, ma sicuramente è un escursione che vale la pena fare e soprattutto la guida è stata gentile e ha capito la situazione.”
