Is it worth it to go to Culebra?
If you are looking to experience a laid-back island getaway, it doesn't get more laid back than Culebra. Culebra is great for a day visit or a weekend getaway. However, keep in mind that this little island is all about the beach and relaxation. There is not a lot going on after hours.
Which one is better Vieques or Culebra?
There are two small islands off the east coast of Puerto Rico, each with major claims to fame: Vieques, the largest island other than Puerto Rico itself, is home to the brightest bioluminescent bay in the world. Another great side trip, Culebra consistently wins prizes for having one of the world's 10 best beaches.
