A Guide to Exploring One of the Caribbean’s Most Vibrant Marine Ecosystems
Just 20 miles off the eastern coast of Puerto Rico, the island of Culebra offers one of the most unforgettable snorkeling experiences in the Caribbean. With crystal-clear waters, protected coral reefs, and a thriving array of marine life, Culebra is a destination that continues to captivate ocean lovers from around the world.
Whether you’re a seasoned diver or a curious first-time snorkeler, the waters around Culebra invite you to explore a hidden world beneath the surface—where sea turtles glide gracefully through reef gardens, colorful fish dart between coral branches, and every breath you take is filled with wonder.
Why Culebra is a Top Snorkeling Destination

What makes snorkeling in Culebra truly special:
- Excellent visibility, often exceeding 60 feet
- Shallow coral reefs, ideal for snorkelers of all levels
- Protected bays and coves, providing calm, safe conditions
- Diverse marine life, including green sea turtles, angelfish, parrotfish, rays, and more
- Minimal boat traffic and development, ensuring a peaceful experience
