Top 5 Snorkeling Spots
Not all beaches are created equal when it comes to underwater scenery. These five locations consistently deliver the most rewarding snorkeling experiences on the island.
Colombier stands out as the undisputed favorite. Its remote location means fewer visitors and a thriving reef ecosystem. Snorkel along the rocky sides of the bay to spot parrotfish, sergeant majors, and even the occasional sea turtle. The hike from Flamands adds to the adventure — or you can arrive by boat for a more relaxed approach.
What You'll See Underwater
St Barts' marine reserve protections have allowed underwater life to flourish. Even without diving deep, you'll encounter an impressive variety of species just below the surface.
- Sea turtles — Green and hawksbill turtles are frequent visitors, especially at Colombier
- Tropical reef fish — Blue tang, angelfish, parrotfish, trumpetfish, and butterflyfish
- Corals and sponges — Brain coral, fan coral, and colorful tube sponges
- Rays — Southern stingrays sometimes rest on sandy patches near reefs
- Octopuses — Well-camouflaged among the rocks, a thrill to spot
Best Conditions for Snorkeling
Timing matters. The dry season from December to May offers the clearest water and calmest seas. Morning sessions are ideal — the water is often glassy before the trade winds pick up in the afternoon.
Reef-safe sunscreen only
St Barts takes marine protection seriously. Use mineral-based sunscreen (zinc oxide or titanium dioxide) to protect the coral reefs you're about to enjoy.
Essential Snorkeling Tips
- Bring your own gear — Quality masks and snorkels are worth packing; rentals can be hit-or-miss
- Wear a rashguard — Better sun protection than sunscreen alone, and it protects the reef
- Don't touch the coral — Even light contact damages years of growth
- Check sea conditions — A quick look at the forecast helps you choose the right spot
Whether you slip into the water at a secluded cove or join a boat excursion to the marine reserve, snorkeling in St Barts reveals a Caribbean underwater world that rivals any in the region.
