The beach can be accessed from the parking area at Flamenco Beach. To reach it, you need to go under the chained gate and follow the narrow path that goes up and over, crossing this part of the island. The path has been cleared of any explosive devices, but the surrounding area may not have been, so it's important to stay on the path. It's advisable to bring only necessary items and wear comfortable shoes (flip flops are not recommended). After a hot and challenging 20-minute hike along a narrow path with shrubs that may scratch you, you will be rewarded with a small, rocky beach area that offers excellent snorkeling opportunities. The path ends at Carlos Rosario. If you take any of the small paths to the left, you will come across Tamarindo Grande (not to be confused with Tamarindo). Alternatively, if you prefer not to walk, you can also opt for a snorkel boat tour.
For snorkelers, if you head all the way to the right, you will find a wall or shelf where some large fish hide under ledges, and the visibility is decent. However, the main attraction is located before that. Walk towards the right, where the rocky area meets the sand, and then swim straight towards the white buoy. On your left, you will encounter unimpressive coral with poor visibility. Once you swim far enough out, turn left, and you will find deeper water with soft coral and plenty of fish leisurely swimming around (I suspect the tour boats feed them). We also had the opportunity to spot jellyfish and two rays, one of which was a stunning, large spotted eagleray.
