Into the Blue: St. Thomas Two-Stop Snorkel by Boat
Two reef stops, clear water, and a fast boat—St. Thomas snorkeling, distilled.
The boat noses out of Charlotte Amalie Harbor like a patient creature testing the morning, and the Caribbean answers in a low shimmer. Trade winds brush the deck. Pelicans skim the surface with a practiced nonchalance. Then the captain opens the throttle and the harbor shrinks, pastel buildings and green hills slipping into a watercolor backdrop while the sea takes the lead. Out here, the water is not one color but a conversation—turquoise handing you to cobalt, then back again. You gear up quickly: mask defogged, fins snugged, the strap of your snorkel settling behind your head like a promise. The ladder kisses the water and the first shock is not temperature; it’s clarity. The Caribbean doesn’t just invite you in. It dares you to pay attention.
Trail Wisdom
Go Mineral, Go Long-Sleeve
Use reef-safe mineral sunscreen and wear a UPF rash guard to protect skin and coral; chemical sunscreens are banned in the USVI.
Short, Slow Kicks
Keep your fins below the surface and use compact kicks to avoid stirring sand or bumping coral in shallow areas.
Pre-Game Hydration
Drink water before boarding and between sites; the Caribbean sun and salt can sneak up on you.
Defog Done Right
Rinse mask once with fresh water, apply a pea-sized defog, then do a single seawater rinse right before entry for clear views.

Conservation Note
USVI’s sunscreen law safeguards coral; avoid touching reefs and give turtles at least 10 feet of space to reduce stress and protect feeding behavior.
Charlotte Amalie’s waterfront warehouses trace to Danish colonial trade routes, when sugar and rum moved through the harbor under the watch of hilltop forts.

Common Questions
Do I need to be an experienced swimmer?
You should be comfortable in the water, but expert skills aren’t required. Flotation aids are typically available and guides stay close for support.
Can I bring my own mask and fins?
Yes. Most tours provide quality gear, but bringing your own ensures familiar fit and a fog-free experience.
What marine life might I see?
Common sightings include green and hawksbill turtles, parrotfish, blue tang, sergeant majors, rays, and occasionally barracuda or squid.
What if I get seasick?
Take a non-drowsy seasickness remedy 30–60 minutes before departure and sit near the stern in the fresh air; avoid heavy meals pre-trip.
Are kids allowed on the tour?
Policies vary by operator and sea conditions; check minimum ages and flotation options before booking.
What happens if weather turns bad?
Captains may change sites for protection or reschedule for safety; the USVI’s microclimates often allow a good alternative cove.
What to Pack
Reef-safe sunscreen to protect both skin and coral; long-sleeve UPF rash guard for sun coverage without reapplying; compact dry bag for phone, wallet, and towel; motion-sickness tablets if you’re sensitive to swells.
Did You Know
The U.S. Virgin Islands banned the sale and use of sunscreens containing oxybenzone, octinoxate, and octocrylene in 2020 to protect local coral reefs.
Quick Travel Tips
Arrive 20–30 minutes early for gear fitting; wear your swimsuit under light clothes; bring cash for crew gratuity; plan a flexible schedule in case weather prompts a site change.
Local Flavor
Refuel island-style: Try conch fritters and johnnycakes at Gladys’ Café, sundowners with a harbor panorama at Mafolie, or a casual toes-in-the-sand meal at Hull Bay for local vibes and surf talk.
Logistics Snapshot
Closest airport: Cyril E. King (STT). Typical departure: Charlotte Amalie or Red Hook marinas. Drive time: 10–30 minutes from most hotels. Cell service: Good onshore, spotty offshore. Permits: None for participants; reef-safe sunscreen required by law.
Sustainability Note
Reefs are living structures—float horizontal, keep fins up, and never stand on coral. Use mineral sunscreen, pack out all trash, and respect wildlife distances to keep this underwater city thriving.
