Dress codes are informal yet respectful. Men tend to wear trousers but shorts are fine, although walking around without a shirt is frowned upon. Women will feel more comfortable in knee-length or longer.
Daytime temperatures are generally warm, so bring lots of light clothing and think about sun protection, including a hat and sunglasses. The evenings tend to be cool, and a light sweater appreciated.
In Volcanoes National Park and Nyungwe National Park slightly heavier clothing is useful. A lightweight waterproof jacket may come in handy in the moist mountains.
Avoid wearing blue in Akagera National Park, which attracts tse tse flies, and take sensible precautions against mosquitos and other bites.
When tracking gorillas, wear sturdier clothing to protect against stinging nettles, and solid walking shoes. Consider bringing gardening or leather gloves as well as gaiters.
For those who wear contact lenses, cleaning fluid is not readily available and dust or sun could prove an irritation, so it’s best to bring a pair of glasses along for peace of mind.
