Gruta das Agulhas

Just go down and listen to the waves

Wow—it’s a big cave! Hop the chain and take the path to the right past the picnic tables and then straight down the concrete stairs. Make a u-turn and walk west across the rocks a short ways, following some sections of poured concrete and stones, and hop over a lip of sharp rock to enter the cave. The lava tube goes back surprisingly far. You’ll need a flashlight to go safely any further than 20 meters. It’s only accessible around low tide. Wear sensible shoes and watch your head.

Follow the other reviews (or Open Street Map) to find the actual cave. Flashlight is necessary.

Very romantic spot with beautiful see view in every weather. There is a place for barbecue and concrete sitting and tables.

Very impressive!
