Kisite Marine Park & Wasini Island Dolphin Trip from Mombasa

From Mombasa to Shimoni: the south coast drive

Shimoni lies close to the Tanzanian border, at the southern end of the Kenyan coast, and it is the departure point for every Kisite Marine Park trip. From Mombasa the road crosses to the mainland at Likoni, then follows the coastal highway south past Tiwi, Diani Beach and the sugar cane and coconut plantations of Kwale County. The drive takes about two to two and a half hours, which is why pickups in Mombasa start early, usually between half past five and six in the morning.

Many visitors ask how to get to Shimoni from Mombasa without a car; on this trip the transfer is part of the day, so you simply rest on the way down while the sun rises over the ocean. Guests staying in Diani are collected a little later on the same route. At Shimoni the crew is ready at the jetty and you set off while the sea is still calm.

Kisite-Mpunguti Marine National Park: reef snorkelling

Kisite-Mpunguti Marine National Park was established in 1978 and protects the reefs around four small coral islands south of Wasini. The fully protected park around Kisite island covers about 28 square kilometres of shallow reef, seagrass beds and sandy channels, while the neighbouring Mpunguti reserve allows traditional fishing by local communities. Its clear, sheltered water makes it the best-known snorkelling area on the Kenyan coast.

The boat anchors close to the reef, where the coral lies only a few metres below the surface. Masks, snorkels and fins are provided, and the crew helps anyone who is less confident in the water. Expect parrotfish, angelfish, surgeonfish, moray eels and, quite often, green turtles feeding on the seagrass. You usually spend about an hour in the water, depending on the tide, and it is the part of the Kisite Marine Park day trip that most guests talk about on the drive back.

Dolphin watching in the Wasini channel

The waters between Shimoni, Wasini and the Kisite reef are home to resident Indo-Pacific bottlenose dolphins, while Indo-Pacific humpback dolphins are seen less often. Pods are most active in the morning, which is when the boat crosses towards the park, and they sometimes ride the bow wave or surface around the boat to feed. From about July to October, migrating humpback whales are occasionally spotted further offshore as well.

The captain slows down and keeps a respectful distance so the animals choose how close they come; the boat never chases or circles them. Dolphins are seen on many trips, but they are wild animals and sightings can never be guaranteed. Keep your camera ready during the crossing and ask the guide to help you tell the species apart as they surface. This dolphin trip from Mombasa is about watching them in their own home, calmly and responsibly.

Wasini Island: Swahili lunch and the mangrove walk

Wasini is a small, car-free coral island across the channel from Shimoni, with two villages, Wasini and Mkwiro, whose families live mainly from fishing and seaweed farming. Swahili communities have lived here for centuries, and old coral-stone ruins stand among the baobabs and coconut palms behind the shore. After snorkelling the boat lands you here for lunch, with seafood as the classic choice and chicken or vegetarian dishes for those who prefer them.

After lunch the guide leads you through the mangroves and the coral garden at the edge of the village, a landscape of fossilised coral shaped by the tides, with mangrove trees growing straight out of the rock. At low tide you see crabs, mudskippers and wading birds; at high tide the mangroves stand in water. The walk takes about half an hour and shows how the mangroves shelter the young fish of the reef you snorkelled that morning.

The Shimoni caves

Back on the mainland, a short walk from the Shimoni jetty leads to a network of coral limestone caves that stretches inland beneath the coastal forest. For generations the caves sheltered local communities during raids, and in the nineteenth century they were used to hold captives before they were shipped to the slave markets of Zanzibar. A small display and the marks left in the rock tell this story with dignity.

The visit takes around twenty to thirty minutes with a local guide and is included in the trip. The caves are cool and home to a colony of fruit bats, so watch your step on the uneven floor. It is a moving end to a beautiful day on the water and adds real history to a trip that many guests book only for the sea, before the drive back to Diani and Mombasa in the afternoon.
