"The entire process of our two Scuba Discover dives went smoothly. On the first day we got an introductory course with an instructor in the pool with full equipment to dive safely in the open sea with great conditions the next day. Near the island of Mnemba at a reef in 12 m depth under water we could admire the colorful corals and fishes then. Between the two dives we were provided with local and vegetarian snacks. On another day we spontaneously went snorkeling and it was almost as impressive as the diving. Great time. The dive center took super care of us. We recommend One Ocean dive center 100%." (Transl.

"My friend and I had super fun diving and snorkeling with One Ocean Diving Zanzibar at Mnemba Atoll. The professional team guided us with the highest safety standards and showed us the amazing underwater world & marine life of the reefs. We even saw dolphins and a small shark on the reef. Especially as a snorkeler I did not expect to be accompanied by a guide as well. The large One Ocean dive center was very concerned about reef-friendly behavior of the guests and pointed us to environmentally friendly sunscreen. We can only recommend this mixture of fun on board and necessary seriousness during the dives for your diving or snorkeling adventure! What I find especially good is that the dive center offers besides the normal diving operation also diving vacations with several resorts and beach hotels in paradise" (Transl. Google)

"I successfully completed my Open Water Diving course up to 18m depth at One Ocean. On the first day I got an introduction in a pool where I learned the basics of diving and how to use the equipment. On the second day we did two dives down to 12m near the island of Mnemba and on the third day even down to 18m. Amazing conditions. Down there we saw a lot of fish and corals, the reefs and also dolphins! My parents kept me company with snorkeling and felt "like in an aquarium". The whole diving team is very nice and funny! Thank you for helping me with the Open Water Training!" (Transl. Tripadvisor)

"The team at One Ocean Diving Zanzibar is top notch! Either start your trip by booking your trip in advance with their easy online booking system, or contact One Ocean directly and get personalized and flexible recommendations. The PADI certified instructors are patient to further educate you in all PADI levels or take you on a fun dive. My son was very nervous at the beginning of his dive course, but ended his course very confident and any fear was gone. Also, the dive masters and snorkel guides who are with you on the fun dive or on the surface allow you to see many colorful fish and coral. They were very helpful and friendly. Many thanks to One Ocean for this great diving experience!"

Anna from Italy

"4 great dives with One Ocean! Two in Stone Town and two in Mnemba island. I felt very comfortable with a very attentive team and a friendly and professional instructor. There were delicious vegan snacks in between the dives. I can highly recommend to go diving on both sides of the island to explore the biodiversity, the different corals on the reef, fish, marine life and lying wrecks. Especially in Stone Town there is no other dive center. This means that you have the dive sites with its super conditions around Stone Town to yourself. If I go on another diving vacation, I will definitely dive with One Ocean again!" (Transl. Tripadvisor)
