Green Island Snorkel with Sea Turtles in Antigua — The Secluded East-Coast Reef Trip

Most of Antigua's snorkel trips run along the busy west and south coasts. This one heads the other way — out to secluded Green Island off the calm, protected east coast, where the water stays clear and sheltered and the crowds simply aren't there. You travel by boat to a tiny island that most visitors never reach, snorkel a healthy reef in search of sea turtles, then have around 90 minutes to yourself on a quiet island beach. It's the pick for travelers who want turtles and reef without the bustle. See how it stacks up against the island's other trips on our antigua and barbuda snorkeling tours page.

The east coast's reefs and outer islands shelter the bay, so even on breezier days the water here tends to stay calmer and clearer than the open Atlantic side — ideal conditions for relaxed snorkeling and good visibility.

The trip is unhurried and personal. A local driver-guide collects you and shares Antigua's history on the scenic transfer to the boat, so the journey is part of the experience rather than just transport. Once you're in the water you snorkel over the reef looking for turtles, rays and tropical fish, then come ashore for beach time on sand you'll likely have almost to yourself.

Green Island's sheltered reef is calm, clear and full of life. On a typical snorkel you can expect:

• Green and hawksbill turtles grazing the seagrass and reef edge
• Vibrant tropical reef fish — parrotfish, sergeant majors and snapper
• Southern stingrays gliding over the sandy patches
• Colorful living coral and sponges along the reef
• Conch and starfish in the shallow seagrass beds
• Clear, calm water with good visibility on most days
• The occasional barracuda or shoal of silversides passing through

What's Included

• Round-trip boat transfer to secluded Green Island
• Guided reef snorkel in search of sea turtles
• Around 90 minutes of beach time on the quiet island
• Snorkel gear — mask, snorkel and fins
• A local driver-guide and island history on the transfer
• Drinking water

Not Included

• Gratuities for your guide and driver (optional but appreciated)
• Your own towel, swimwear and reef-safe sunscreen
• Food and extra drinks unless otherwise noted

A little preparation makes the day smoother. The water is calm and sheltered, but this is still an open-water snorkel from a boat, so basic swimming confidence helps.

• What to bring: swimwear under your clothes, a towel, reef-safe sunscreen, a hat and water
• You should be comfortable in the water — bring a flotation aid if you're a nervous swimmer
• Turtle etiquette: keep your distance, never touch or chase the turtles, and don't block their path to the surface
• Not allowed: no touching the coral or reef, no standing on the reef, and no feeding marine life
• Reef-safe sunscreen only — apply it well before you get in to protect the coral
