Flamenco beach is one of the best beaches I have ever been too, but you have to plan it out since it’s on an island and ferry schedule. The bioluminescence is really cool, so try and plan away from a full moon. There is a restaurant next to a McDonald’s there near the airport which is super delicious. Amazing Hikes in the national forest, cool waterfalls. The other side of the island has some cool caves but it’s a bit of a drive.
