The accommodations provided in the national parks by UWA are generally of a good standard and are quite inexpensive compared to alternatives. They vary in amenities and price, and the cheapest can be as little as USD5.00 or less per person per night.
Few moderately priced options are available, and the high end, while expensive, are substandard compared to the high end options of Kenya, Tanzania, South Africa and other mature tourist destinations in Africa. Unfortunately, few alternatives are available. There are some notable exceptions, but best to go either highest end or stay in the UWA budget accommodations and spend more on a better vehicle!
