Bacia da Sereia is one of those places that only those who know Ilha do Mel well visit.

If you're searching for "bacia da sereia", "natural pool ilha do mel", or "snorkeling ilha do mel", this guide has everything: how to get there, when to go, what to bring, and why this place is a secret kept by locals.
What is Bacia da Sereia?
Bacia da Sereia is a natural rock formation that creates a pool isolated from the open sea. At low tide, the water stays still, crystal clear, and warmed by the sun — perfect for a long swim and snorkeling. At high tide, the sea invades the pool, making it deeper and connected to the ocean.

How to get to Bacia da Sereia
Access is via an easy 15-minute trail starting from Praia de Encantadas. The route follows the coast toward Gruta das Encantadas — Bacia da Sereia is on the way, about 5 minutes before the grotto.
The final stretch passes over wet rocks, which can be slippery. Sneakers recommended.
Local tip: combine Bacia da Sereia with Gruta das Encantadas in a single outing. It's 15 min of trail to the pool, plus 5 min to the grotto. Return via the same trail.

Best time to visit
Bacia da Sereia only works at low tide. At high tide, access is covered and the pool loses its characteristic calm water.
- Ideal time: between 8am and 1pm (usually low tide during this period)
- Best season: March to October (less rain, more predictable tides)
- Avoid: summer afternoons without checking the tide — it may be high
Tip: bring a snorkeling mask. The crystal-clear water lets you see small fish, sea urchins, and colorful algae on the rocks.

Why the name "Bacia da Sereia"?
The name comes from the local legend that says mermaids inhabited the calm waters of the pool, attracted by the protection of the rocks and the warm water. The legend of the Encantadas — which gives its name to the neighboring village — is directly linked to this place.
