Island snorkelling at Bongoyo is a half-day boat trip from the Slipway jetty on the Msasani Peninsula in Dar es Salaam, Tanzania, to Bongoyo Island, one of the islands of the Dar es Salaam Marine Reserves System. The island lies roughly 7 km offshore, and small motorised boats from the Slipway jetty cross in about 20 to 30 minutes in calm conditions. Visitors pay for the boat and the marine reserve entry fee at the jetty, and most operators rent masks, snorkels and fins on the island or on the boat. Typical all-in costs run from about 100,000 to 150,000 TZS, depending on the number of passengers and the gear hired.
The activity needs no prior experience. Snorkelling over the shallow fringing reef and sandy patches off the island is suitable for confident swimmers, and many visitors also stay in shallow water close to the beach. There is no formal age limit, but children should wear a life jacket and be supervised by an adult at all times. Anyone with ear, heart or breathing conditions should seek medical advice before snorkelling.
Equipment is partly included: masks, snorkels and fins are generally available for hire at the island, while swimwear, reef-safe sunscreen, water shoes and a hat should be brought. Marine reserve rules prohibit collecting shells, coral or other marine life, and standing on or touching the coral damages the reef.
There is no single certified operator; the boats are run by independent captains working from the Slipway jetty, and standards vary. Visitors should check that the boat carries life jackets and has a working engine before departing. Safety briefings are informal and usually limited to boarding instructions and swimming areas. There is no organised rescue service on the island itself, so help in an emergency means returning by boat to the mainland, and the island has only basic facilities.
The best conditions are generally from June to October, when the southeast monsoon (kusi) brings drier, cooler weather and clearer skies, although the sea is often calmest between roughly June and March. Visibility drops after heavy rain, when runoff clouds the water, and the crossing can become rough in strong winds. Visitors should avoid the rainy months of April and May, when trips are less comfortable and sometimes cancelled. Many visitors combine the snorkelling with a beach lunch and a short walk on the island's trails.
