The answer obviously depends on what you are planning to do during your Gambian holiday and when you will be travelling. The climate is sub-tropical so remember to pack clothes made of light fabrics and linen. And sun screen – plenty of sun screen!
Although the Gambia
is a Muslim country, it is fairly liberal when it comes to dress code. You will therefore also see local men and women walking around in shorts and t-shirts. For trekking and other wildlife excursions, you should bring appropriate, comfortable footwear and long trousers with a bit of thickness in order to protect you against thorny vegetation.
Long sleeves protect you against mosquito bites on your arms, but you should also bring insect repellent and soothing lotions.
