Don't believe the reassuring smiles of your local travel agent. Kenya is dangerous. There is much political instability, the population is mainly extemely poor, and there are few services available to make people's lives easier. Happily, the latter does not happen too often, but you will hear stories of theft and mugging from many visitors.
Most hotels have bars on the rooms' windows.
All this is a real shame, since most of the Kenyan people are interesting, and interested in tourists. If you do want to go, carry virtually no money with you, take no watches, jewellery or other valuables onto the streets. You will want to look like it's just not worth mugging you. A higher number indicates a higher risk to travellers. Find out more information about the index , or visit our security index league table of countries.
