Where the falls meet the lake
The Kalambo River reaches the edge of the Tanganyika rift escarpment at the south-eastern corner of Lake Tanganyika and drops into a quartzite gorge on the Tanzania–Zambia border. UNESCO’s documentation records that below the fall the river meanders north-east through interlocking spurs for eight kilometres before forming a small delta on the lake.
That eight kilometres is the reason the falls belong on the lake’s page as well as their own. On the Tanzanian side the site is protected as the Kalambo Nature Forest Reserve, which has its own guide here and covers the height dispute, the archaeology and the UNESCO position in full. This page covers the approach and what the Tanzanian authorities have actually done at the site.
The height, briefly
Tanzania Forest Services publishes 235 metres. Tanzania’s state newspaper has printed both 221 and 235 metres. Zambia’s submission of the site to UNESCO’s tentative list, in March 2026, describes the falls at length and gives no height for them at all — while giving two different elevations for the site itself, 1,150 metres in one paragraph and about 1,390 metres in another.
No rank is published here. TFS calls it the second highest free-falling waterfall in Africa and Kalambo District Council calls it the second largest waterfall in Africa; those are two different claims from two Tanzanian bodies, and neither is supported by a source that ranks waterfalls. The reserve guide sets the whole question out.
The staircase, and two figures for it
Getting down towards the falls on the Tanzanian side has been the subject of actual construction, and the record of it is more specific than the travel copy.
The Rukwa regional authorities’ own account of their 2017/18 tourism work at Kalambo lists the improvements made: thirty kilometres of reserve boundary cut and 83 boundary stakes placed; drawings prepared for a tourism centre with a gate, a manager’s office, an information centre, a hall and a cultural centre; areas planned for guest accommodation and services; signs placed at Kapozwa village; and the building of a 227-metre staircase to the falls on the edge of the Kalambo gorge, then still under way.
A different figure — 1,270 steps — is attributed to a regional official’s account and circulates widely. The two are not necessarily in conflict, since one is a length and the other a count, but neither is a completed specification, and TFS’s own description of the reserve mentions no staircase at all. Ask about the condition of any stairway before planning to descend it.
Reaching it from the lake side
TFS gives the road approaches as about 440 kilometres from Mbeya via Sumbawanga, or about 277 kilometres from Mpanda. It names Kasanga Port on the lake among the nearby attractions, along with the Bismarck ruins and the Great Rift Valley viewpoint at Mbizi Forest, and the reserve itself holds a beach on the lake shore. A hot spring at Kizombwe village is listed by TFS among the reserve’s attractions, though Rukwa’s regional account places Kizombwe in Sumbawanga District Council instead.

Common questions
How high is Kalambo Falls?
Disputed. TFS publishes 235 metres, Tanzania’s state newspaper has printed both 221 and 235, and UNESCO’s Zambian submission gives no height. No surveying authority publishes one.
Is the archaeology on the Tanzanian side?
No. The excavated terraces are on the Zambian bank, and Kalambo is on Zambia’s UNESCO tentative list rather than Tanzania’s. The reserve guide covers what was found there.
Is there a staircase down to the falls?
Rukwa’s regional account records a 227-metre staircase under construction in 2017/18. A figure of 1,270 steps circulates from an official’s account. Neither is a confirmed current specification.
