Lake Tritriva is a volcanic lake in southwest-central Madagascar, in the region of Vàkinankàratra, located near the village of Belazao. In a distance of 15 km from Antsirabe, it is easy to reach by the National Road 34.[4]
There's a strict Fady (taboo) for this lake and swimming is not allowed.
The lake fills an extinct crater[5] in a region notable also for the presence of many hot springs. It sits in the vent of an oval volcanic cone enclosed in vertical gneiss cliffs.[1] The rim of the cone is about 2,000 m (6,600 ft) above sea level, while the surface of the lake is approximately 50 m (160 ft) below the rim.[1] The lake's water level drops during the rainy season and rises when the monsoon rains have ceased.
The lake is up to 160 m (520 ft) deep.[3]
