Originally the trail began right against the Kenyan border, though recently the trail shifted eastwards and now starts at the Tanzanian town of Loitokitok, after which the new trail has been named (most trekkers refer to this trail as the Rongai Route).
As this is an isolated route less frequented by trekkers, it is likely that you will encounter wildlife, as animals tend to gather where humans don’t. Trekkers will also be rewarded by the vast number of unique plant life that is prevalent in the rain forest, mooreland and the semi to alpine desert zones.
