Juncalinho Natural Pools
Sea-filled basins in the black lava on Sao Nicolau's northern coast, used for swimming when calm.
Updated 21 October 2026
At Juncalinho on São Nicolau's northern coast the lava runs out flat to the sea and the waves have worn basins into it, filled and refreshed by the surge, deep enough to swim in when the water is calm. The rock around them is jagged black volcanic stone and the surf breaks on the outer edge. Steps and a handrail have been put in at the main pool, and the village sits a short way inland.
What's there
- The lava pools - basins worn into the black rock and filled by the sea.
- The surge - waves refreshing the pools over the outer edge.
- The black rock platform - the jagged lava shelf the pools are cut into.
- The village - the settlement a short way inland from the shore.
When to go
November to June is the dry season and calmest. Swimming is only sensible in flat conditions. Winter swell closes the pools entirely.
What to expect
In any swell the pools are genuinely dangerous. The lava is sharp and cuts badly. There are no lifeguards or facilities.
Nearby
Carberinho is west, and Ribeira Brava is south.
