Lake Chala Day Trip

Lake Chala is a crater lake sitting on the Tanzania–Kenya border, about 50 kilometres east of Moshi, and the reason to go is that it looks like nowhere else in this region. The crater walls drop roughly 100 metres to the water. The lake is deep — over 90 metres in places — and it changes colour through the year from deep blue to a striking blue-green depending on the season and the algae.

Morning: The drive takes around 90 minutes, the last part on dirt through sisal estates and small settlements. You arrive at the rim, and the lake is entirely hidden until you are almost on top of it: the crater is invisible from the approach, and then the ground simply falls away.

Getting down to the water is a proper descent — a steep path with steps cut in places, about 15 minutes down and rather longer coming back up. It is the only real effort of the day.

Midday: At the shore there is a small beach area. Kayaking is the best way to experience Chala; on the water you get the full scale of the crater walls, and you can paddle towards the invisible line where Tanzania becomes Kenya. Swimming is possible in the designated area.

One honest safety note: Chala has a history of crocodile presence and there was a fatality here some years ago. Local guidance now designates where it is safe to enter the water, and we follow it strictly. If you would rather not swim, kayaking gives you the lake without the question.

The birdlife around the rim is excellent — over 200 species recorded — and the forest that clings to the crater walls holds vervet monkeys and, occasionally, baboons.

Lunch is a picnic on the rim with the lake below and, on a clear day, Kilimanjaro filling the horizon behind you.

Afternoon: The climb back up, then the drive to Moshi, arriving late afternoon.

What to bring: good shoes for the descent, swimwear if you plan to get in, sun protection — the rim is exposed — and a camera with something wide, because the crater does not fit into a phone frame.

Best time: Year-round. The colour is often at its most intense towards the end of the dry season.
