Tanzanians don’t have a very strict dress code when it comes to foreigners. Our advice would be to respect the people as you would in any other country. Most Tanzanians are Christian, although there are around 25-30% Muslim in the towns of Arusha and Moshi. During the day shorts and tee shirts will be fine. When out and about in the evening casual clothing such as long trousers and shirts and long dresses and blouses are more appropriate. Clothing and equipment not needed on the trek can be safely left at the hotel whilst you are climbing Kilimanjaro.
