How can I get around?
Most hotels have a taxi rank nearby. It is best to agree the price in advance and there should be a price board displaying the tariffs. Although taxis are regulated, many wouldn't pass a UK MOT test! The only public transport are Bush Taxis which cover the main routes and some bush roads, but do not run to a schedule. They are cheap and very over-crowded but are a great way of absorbing the local flavour.
If you have an idea of places you'd like to visit, speak to your representative in resort and you'll find you can book a private guide with relative ease. You can plan an itinerary, agree a price and your driver will stay with you all day and take you wherever you need to go. It's a great - and relatively cheap - way, to see The Gambia.
The Gambia is generally speaking a very safe country, and taxis and Bush Taxis are all regulated by the government. Similarly, if you check with your representative and hotel first, you'll find all private guides helpful and respectful. As in any foreign destination, always keep your belongings with you and take care at all times.
