The currency in Kenya is the Kenyan shilling (Ksh or KES) which is in turn divided into 100 cents. There are notes of 10, 20, 50, 100, 200 and 500 shillings in circulation. The currency is still not stable. It is best to consult a financial resource a week before departure. On the internet for example you can check www.oanda.com.
It is not possible to buy Kenyan shillings in advance, just as it is not possible to buy dollars and euros inside Kenya. You will have a chance immediately after arrival at the airport in Kenya to exchange euros and U.S. dollars for shillings. There is also an ATM at the airport where you can withdraw money. In many places in Kenya, it is possible to use ATMs. Keep in mind that in Kenya the power occasionally fails and then you can not use the ATM.
In Kenya, credit cards are rarely accepted. You can only use them in some supermarkets (in combination with your passport for identification purposes) and at expensive hotels. Never exchange money on the black market because the chances are that you will get your hands on counterfeit money. Try to get small denominations of Kenyan shillings when you change up money, this makes life easier as places will often have no change for larger bills. You may also take part of your money in the form of traveller's cheques, these are insured against theft and loss. That said, travellers cheques are not always so convenient, you often have to wait a long time at the bank to cash them in.
We recommend taking 2/3 of your pocket money in euros and 1/3 in U.S. dollars. With dollars it is easier to pay the entrance of the parks(Hell's Gate - and Nakuru NP). Please note that dollar bills printed before 2004 are not accepted.
The suggested ''Pocket money" represents a minimum amount for your meals, drinks, optional excursions, entrance fees, local airport taxes and gratuities. The amount you actually spend will depend a great deal upon your own habits, therefore souvenirs are not budgeted for in this amount.
