Culabrita is a small uninhabited island off the northeast of Culebra. The 1 mile long by 1 mile wide island is accessible by boat and is part of the national wildlife refuge.
On the north side of Culebrita lies Tortuga Beach. A popular spot to dock your boat and swim with the sea turtles before heading up the hill to the light house ruins.
If you are up for a hike the caribbean's oldest light house lies in ruins at the top of the hill and the view from the hilltop to the ocean below is glorious. The hike is short, but steep so wear hiking shoes and leave your flip flops on the boat.
On the east side of the island there are tidal baths where you can swim and snorkel with the small marine life. The path here is rocky so bring some water shoes.
