Lake Chala is a striking crater lake about 55 kilometres east of Moshi, straddling the Tanzania-Kenya border at an elevation of around 850 metres. The lake sits inside a steep-walled volcanic crater, with no river inflow or outflow visible at the surface — it is fed by underground springs and drained the same way. The water is a deep, glassy blue-green, and the crater walls drop steeply to the shore.
It is possible to hike down to the lake shore from the rim, and kayaking on the lake is available through local operators. Camping on the rim is also an option. The drive from Moshi passes through farmland before the landscape becomes drier and more dramatic near the Kenyan border. Most visitors combine Lake Chala with a stop at the nearby Taveta railway station or make it a standalone half-day trip from Moshi.
