Banking and cash

Kenya has a modern banking system. The major banks include Barclays Bank, Standard Chartered, Kenya Commercial Bank, and CitiBank. Most major banks have automated teller machines (ATMs). However, not all banks have networks in the countryside, and it is advisable to get cash from the major cities or from the airports, where all major banks are represented. Most commercial banks are generally open from 09h00 to 15h00 Monday to Friday, and from 09h00 to 11h00 on Saturday.

Most major credit cards such as Master Card, Visa, American Express, Diner’s Club and their affiliates are widely accepted. Signs will be clearly displayed in places where credit cards are accepted.

The official currency is the Kenya Shilling (Kshs) which is divided into 100 cents.
Bank notes currently available are Kshs1,000, Kshs500, Kshs200, Kshs100, Kshs50,and Kshs20.
Coins are Kshs40, Kshs20, Kshs10, Kshs5, and Kshs1. Most establishments accept Visa or Master Card. Traveller’s cheques are recommended for covering any incidental costs during the safari, although they are not readily accepted by the Curio vendors and other small traders.
