On the island you can find two hiking paths. One which crosses from the Southern beach to the Northern side of the island and one that forks off to the top of the lighthouse.
These hikes are quiet easy; and particularly the one to the lighthouse offers splendid views over Culebrita and the neighboring islands of Culbebra, Esperanza and Puerto Rico, the US and British Virgin Islands in the distance.
The entire island is surrounded by stunning reefs with crystal clean seas. The best snorkeling reefs one can find on the Southern Island between Culebrita and the island of Culebra. Remember when you go snorkeling here that this is a fragile ecosystem and once it is broken it will take years to repair itself.
There are six beaches on Culebrita, the chief being Playa Tortuga (Turtle Beach). The beach is named for the many sea turtles that use the beach for breeding grounds and the surrounding waters for grazing. The other two large beachs are Trash Beach and West Beach. Trash Beach is on the windward side of the island and debris is often blown onto the beach. There are also large tidal pools on the east side of the island where people lounge as if they were large baths.
The island of Culebrita is a turtle nesting ground; therefore no camping, open fires or pets allowed on the island. Also there are specific regulations where to drop the anchor of your boat or yacht.
If you sail from the US Virgin Islands or British Virgin Islands across to Culebrita and anchor off the island you have to inform US officials. A board on the Northern side of the island provides numbers both locally and in San Juan in case you arrive on Sunday's or after hours.
