Mountain biking in East Africa is really a stunning experience for the fit and adventurous tourist.
Many lodges and camps, and even some national parks offer a mountain bike rental by the hour. Mountain biking in Tanzania can be done almost everywhere in valleys, mountains, villages, towns, in the tropical forest, savannah, in semi-desert areas and in wilderness past herds of zebras, elephants, giraffes and antelopes. You should only avoid the traffic and roads.
In Tanzania mountain biking is mostly done in the northern part, especially around Lake Manyara National Park and the Kilimanjaro National Park. There are several mountain biking options.
You can bike only for a few hours to explore the surrounding of your lodge or camp, or you can even undertake a mountain biking tour (from Kilimanjaro to Ngorongoro or even as far down as Lake Manyara, or if you are up to a real challenge a mountain biking trip from Dar es Salaam to Nairobi).
