Singani Lava Flow
A recent Karthala flow that ran to the sea, crossed by the coast road.
Updated 2 October 2026
South of Moroni the coast road crosses a black lava flow from Karthala that ran down the western flank and into the sea at Singani, a field of jagged basalt with the surface textures of the flow preserved: ropy folds, blocks and channels. The road was cut through it. It is the most accessible place on the island to walk on recent lava and see what the volcano does to the coast.
Highlights
- The flow surface - ropy folds, blocks and channels preserved in the basalt.
- The sea end - where the lava reached and entered the water.
- The road cut - the route driven through the flow.
- The Karthala evidence - a recent flow from the island's active volcano.
When to go
May to October is the drier and cooler season. The rock is there year round. Midday heat on black lava is severe.
Practical notes
The rock is sharp and uneven and shoes are essential. There is no path, signage or facility. Black basalt gets extremely hot in the middle of the day.
Nearby
Moroni is north, and Iconi is between them.
