Buck Island: The Reef That Demands a Return Trip
A short boat ride from Christiansted takes you to one of the Caribbean’s best-preserved snorkel reefs.
The boat slips away from Christiansted like a secret being let go — a low, steady pulse of engine and the lick of wake against the hull. In minutes the harbor and its pastel clapboard houses retreat and the sea opens into a light that seems sculpted for snorkeling: translucent turquoise, then cobalt, then the dark-green hum of reef. You can feel Buck Island before you see it; the water tells you the story with a chorus of fish and a brightness that suggests coral gardens beneath.
Trail Wisdom
Book a morning departure
Visibility is typically best mid-morning before winds pick up and boat traffic increases.
Use a snorkel vest
A flotation vest conserves energy on longer swims and allows you to focus on marine life without fighting currents.
Choose a mooring-friendly operator
Pick a tour that uses moorings rather than anchors to protect the reef and comply with park rules.
Bring reef-safe sunscreen
Oxybenzone-free SPF helps protect corals and is often required by responsible operators.
Local Knowledge
Hidden Gems
- •Windward sandbar near the western lagoon — quiet at low tide and perfect for shoreline photography.
- •A small patch of seagrass north of the main snorkel trail where juvenile fish congregate, great for macro observation.
Wildlife
Hawksbill sea turtle, Colorful parrotfish
Conservation Note
Operators use moorings and the park enforces no-anchor zones; visitors are encouraged to use reef-safe sunscreen and avoid touching coral.
The island was designated a national monument in 1961 to protect its coral reef and coastal habitat, anchoring decades of conservation effort.

Summer brings warm water temperatures and vibrant reef life, but expect more humidity and occasional storms.
fall

Challenges: Higher wind and swell potential, Hurricane season runs through November
Autumn can produce dramatic water conditions and excellent marine movement, but check forecasts and book flexible trips.

A properly fitted set improves visibility and reduces fatigue so you can enjoy longer, more comfortable swims.
Snorkel vest or life jacketEssential
