What is confirmed
Kisasa is a waterfall in the West Usambaras, at Ngulwi in Lushoto District. Tanzania Forest Services confirms it by name, listing Kisasa Waterfall among the attractions near Magamba Nature Forest Reserve — alongside the Irente and Mambo viewpoints, the German cemetery and the Lushoto vegetable farms.
That listing does two useful things at once. It establishes that the waterfall exists and that a national agency knows where it is. And it places it outside the reserve, which means TFS neither manages it nor charges for it, and none of the reserve’s trails, fees or opening arrangements apply.
What is not published
Everything else. There is no published height, no walking distance, no walking time, no described route and no managing body. Lushoto District Council publishes no tourism material of any kind. Figures and durations for Kisasa exist only in informal sources that do not agree with one another, so none is repeated here.
A small naming point worth carrying: TFS writes Kisasa Waterfall, singular. Itineraries frequently write Kisasa Waterfalls, plural, which may reflect more than one drop or may simply be habit. No authority resolves it.
What a visit involves
It is a walk from the road through farmed and forested hillside, arranged locally in the village rather than at a gate. The West Usambaras are wet by design — it is what has kept their forest alive — and paths to falls in this range are slippery in every season, not only in the rains. The waterfall hiking guide covers what that actually demands, which is footwear and patience rather than fitness.
Kisasa fits into the same few days as the forest walking inside Magamba and the village-to-village walking the range is best at. See the forest walk guide and the mountain trekking guide.
Common questions
Is Kisasa inside Magamba Nature Forest Reserve?
No. Tanzania Forest Services lists it among the attractions near the reserve, not among the reserve’s own features. Nothing about Magamba’s management applies to it.
How high is the waterfall?
Not published. No government source gives a height, and the informal figures in circulation disagree with each other.
How long is the walk?
Not published either. It is arranged in the village, and the time depends on where you start from, which nobody documents.
