Kilimanjaro, Tanzania generally has a reputation as a welcoming place for travelers. The local people are friendly and respectful, but as anywhere else, it's important to take precautions. Stick with reputable tour operators when arranging your climb. Drug and alcohol-related problems can occur, particularly in climbing camps, so be wary of anyone appearing under the influence. Crime rates are relatively low, though petty theft can happen, so keep your valuables close. Also, it's important to note that healthcare facilities are not always up to western standards. Overall though, it is seen as fairly safe for solo female travelers.
