A reef offshore and
a forest behind the beach.
Diani runs for about seventeen kilometres along the coast of Kwale County, an hour south of Mombasa. The sand is the fine white coral kind that stays cool underfoot, and a fringing reef sits a short way offshore, which keeps the lagoon flat and turns the whole stretch into safe swimming water. Behind the hotels there is still coastal forest holding one of the last viable populations of Angolan colobus in Kenya, which is why you see rope bridges strung over the main road.

Why visit Diani
Fine white coral sand that does not hold heat, which matters when you are walking on it at midday.
The reef breaks the swell, so the water inside stays flat and safe for swimming and paddling.
The forest strip behind the beach holds a rare primate population, and there is a local project working to protect it.
Steady cross-shore wind through the Kusi season makes this one of Kenya’s better kitesurfing spots.
A short flight from the Mara or a drive from Tsavo, which is why bush-and-beach itineraries end here.
Development is low-rise and spread out, so the beach never feels stacked.
What there is to do
Snorkeling & Diving
The reef sits close in, so both are shore or short-boat trips rather than long crossings.
Dhow Sailing
Traditional lateen-rigged boats, best taken late in the afternoon when the wind drops.
Colobus Conservation Visit
A local project working on colobus protection and the rope bridges that keep them off the road.
Kite Surfing
The reliable cross-shore wind makes this one of the better spots on the Kenyan coast.
Dolphin Watching
Early boat trips to the reef edge, timed for the calmest water of the day.
Marine life and wildlife
Colobus Monkey
The Angolan colobus is the coast’s signature primate, and Diani has one of the last viable populations.
Dolphin
Bottlenose and humpback dolphin work the reef edge, most often seen on an early boat trip.
Sea Turtle
Green and hawksbill turtle feed on the seagrass and nest on these beaches between March and July.
Starfish
The shallow lagoons at low tide are full of them, which makes them the easiest marine life to show children.
Reef Fish
Parrotfish, angelfish, snapper and butterflyfish across the coral. Visibility decides how much you see.
When to go
The coast runs on two monsoons rather than a dry and wet season. Both have their advantages.
Kusi season
The south-east monsoon. Cooler, breezier and dry, with the best conditions of the year for being outdoors.
Kaskazi season
The north-east monsoon brings hot, still, humid days and the calmest, clearest water for diving.
Short rains
Brief afternoon storms that clear quickly, warm sea and noticeably lower rates.
Long rains
The wettest stretch, with reduced visibility underwater and some hotels closing for maintenance.
