Everyone knows about the Caribbean. But when it comes to Culebra, is that Nani? Culebra is a small island in Puerto Rico, a free state in the Caribbean. The biggest motivation for me to come to Culebra is to see the world's third-ranked beach, Flamenco Beach. I have been to too many beaches, but the moment I stepped onto Flamenco Beach, I knew I was in the right place. The softness and cleanness of the sand, the clearness and clarity of the sea make me linger. The reason why the Culebra Island is so beautiful is that there are not so many tourists, and the development level is not as good as that of the island of Puerto Rico, but it also retains the originality and quietness of nature. On Culebra Island, we have snorkeled in several areas, and there is a place where you can see turtles, which is exciting. When you are tired, you can enjoy an unlimited supply of buffet on board. Our guided tour of the boat slammed into the sea and picked up a sea urchin. Touching the thorn of the sea urchin, I found it softer than I thought, so I boldly put it in the palm of my hand. Of course, we quickly sent it back to the Caribbean Sea to which it belongs. If it weren't for Puerto Rico, I wouldn't know that the small Culebra was a paradise hidden in the Caribbean.
