Mombasa houses Kenya's largest seaport, the Kilindini Harbour. Being the primary coastal city, Mombasa caters to a mixture of businesses, traders, laborers and cultures.
The beaches near and beyond the city limit offer hotel accommodations and water activities. An active coastal tourism adds to the city's profit, but the main source of income originates from its port related duties. The city also gains revenue from a local cement factory and an oil refinery.
