Culebrita is an uninhabited island off Culebra's east coast. It is a very beautiful island with even more beautiful beaches. It has two main beaches, Tortuga Beach and Playa del Sur (South Beach). Tortuga Beach is by far the more popular beach. Many consider it to be Puerto Rico's best beach. I love Flamenco Beach, but I won't argue with Tortuga's beauty. It also has a natural pool. Playa del Sur is great in its own right. It is smaller and has less beach, but I find it has better snorkeling. It is also more secluded and quieter. Tortuga Beach's biggest problem is it is so popular it can get too crowded. Unless, you have no other option, I would say suggest avoiding this beach on the weekends and holidays. It becomes a marina, so many boats. That also means somebody is more than likely to fill the air with music blasting from their stereos. Their inner dj fills them with the need to make sure everybody on the beach knows what they are jamming. If you are interested in sampling both beaches, there is a trail that crosses the middle of the island d and connects both. I believe it is takes 15-20 min.
Another hike I strongly recommend is the hike to see the ruins of the old lighthouse. It takes about 15-20 min and is an easy hike. Best to wear shoes or sandals that aren't flip flops. But if flip flops are all you have then it's fine. My wife hiked it in flip flops. You will notice a dried up lake in the middle of the island. The view from the top is spectacular. There is the lighthouse itself, but the real prize is the view. You can see the whole island and beyond. Breathtaking. There is Cayo Norte, a smaller island, to the north, and some other tiny island's. To the west is Culebra, maybe even Vieques on a clear day. South is the open sea, and to the east, on a clear day, you can see St. Thomas. Excellent photo and selfie ops. As you cross the middle of the island, on either hike, you might hear or see goats or deer.
Culebrita is a must visit of you are staying a couple of days in Culebra. The only way to get there is by boat. If you don't own one or have friend that does, you can always male a reservation with a water taxi service or charter an excursion. There are a couple that offer rides to Culebrita, and other places such as Cayo Luis Peña (great for snorkeling). H20 Water Taxi, Cato Norte Water Taxi, and blue Water Excursions are some examples. The each have a Facebook page with more info, as well a a Yelp page. You can always ask local businesses about other services and/or their recommendations.
