A small airstrip is located between the beach area and the Mombasa-Lunga Lunga road. The water remains shallow near shore, with some underwater sandbars near the surface which allow wading with a clear view of the sandy bottom. Inland from the beach, there is extensive vegetation (see photo at right), including numerous palm trees which cover the coastal areas, unlike the dry acacia trees of the mountainous Kenyan Highlands. The Mwachema River flows into the sea at Diani Beach.
The general area is known for its coral reefs, black-and-white colobus monkeys, and for the closely located Shimba Hills National Reserve, a wildlife reserve which looks out over the Indian Ocean. Diani Beach has restaurants, hotels, supermarkets, and several shopping centres.
Diani Beach is also a popular kitesurfing location.
