St Thomas~St John Snorkel, Swim & Beach Trip on MV Island Flyer

The best part of this four-hour trip is its small-group format. With no more than 12 people aboard, you spend less time waiting for a crowded boat to clear and more time choosing a good place to snorkel. The route from Red Hook to St. John also gives you a fast, scenic taste of the islands.

I like the well-kept snorkel gear and the steady supply of water, soda, and beer. I also like that the crew can adjust the stops for weather and sea conditions, which has led to memorable sightings of turtles, rays, nurse sharks, squid, and barracuda. The main catch is that the beach stop may require a swim from the boat, and snorkeling quality can vary from one site to the next.

• Maximum of 12 people: A quieter alternative to a large catamaran or party boat.
• Two main stops: Usually one snorkel site and one beach or second snorkel location.
• Several possible sites: Maho Bay, Honeymoon Beach, Lovango Cay, Christmas Cove, Trunk Bay, and nearby cays may be used.
• Wildlife can be excellent: Turtles, stingrays, nurse sharks, eagle rays, squid, starfish, and reef fish have all been spotted.
• Drinks are included: Water, soda, and beer are available after snorkeling.
• Good planning matters: Bring a towel and reef-safe, non-aerosol sunscreen, and allow time to park in Red Hook.

A Small Boat Ride From Red Hook to St. John

You meet the captain and crew at the Seas the Day departure lounge at American Yacht Harbor in Red Hook. The lounge is on the lower floor, across from the entrance to B Dock. From there, you board one of several comparable powerboats, including the 36-foot MV Island Flyer, a 36-foot Twin Vee, or a 31-foot Wellcraft.

The exact boat matters less than the size of the group. A maximum of 12 people gives the outing a personal feel without requiring a private charter price. You can hear the captain, ask questions, and get in and out of the water without the long loading process common on larger vessels.

The boats are open to the sea but have cover, which is useful in strong sun or passing rain. The ride itself can be quick and lively. One section between the islands has been described as a washing machine when waves meet, so you should be comfortable on a powerboat and ready for some spray or chop.

Parking around American Yacht Harbor can be tight. If you are driving, allow extra time, and check the ferry parking area for availability. The departure point is near public transportation, and the trip returns to the same marina after about four hours.

Choosing the First Snorkel Stop

The captain decides where to stop based on wind, waves, water conditions, and what will offer the best outing that day. Possible locations include Maho Bay, Christmas Cove, Trunk Bay, St. James Island, Lovango Cay, Mingo Cay, Stevens Cay, and other nearby waters.

That flexibility is useful because conditions change quickly around St. Thomas and St. John. A calm morning at one bay can turn choppy later, while a less familiar cay may offer clearer water and fewer boats. You should not book this expecting one fixed site or one guaranteed animal encounter.

Maho Bay is a popular choice because turtles often feed in the seagrass. It can also be a busy stop, and the boat may anchor farther out in deeper water. One account described a roughly 100-yard swim to reach the seagrass from the anchorage. That can be rewarding for a strong swimmer, but it is not ideal if you want to float straight from the boat into shallow water.

Lovango Cay has also produced some excellent snorkeling. The water there may be around 12 feet deep, and the coral restoration work near Lovango has helped create an interesting place to look for fish. Christmas Cove and the nearby cays can offer a more boat-accessible experience, with reef areas that you might not reach from a public beach.

The crew supplies masks, snorkels, and fins. The equipment has received strong marks for condition, but fit still varies from person to person. If you are particular about your mask, bring your own if you have room. You should also be comfortable in open water and have at least a moderate level of physical fitness.

What You Might See Below the Surface

The water around St. John and the nearby cays is home to snapper, parrotfish, squirrelfish, surgeonfish, and other reef species. The sightings can go well beyond small tropical fish. People on this trip have encountered sea turtles, stingrays, spotted eagle rays, nurse sharks, barracuda, squid, starfish, jellyfish, and even a shipwreck.

The most useful expectation is a realistic one: the captain can choose a promising site, but no one can order wildlife to appear. Some outings produce several turtles and rays. On others, the reef may look quiet. One captain described a turtle as acting shy, which is a fair way to think about wildlife here.

The best captains add context without turning the trip into a lecture. Hillary has been praised for spotting sea life, while Glen, Mike, Dallas, Wallens, Montana, Thomas, and Sammy have each been singled out for local information, friendly service, and careful boat handling. The exact captain depends on the day, but the crew’s local familiarity is a major part of the experience.

Bring an underwater camera if you have one. Turtles surfacing near the boat, purple and elk-horn coral, squid, rays, and clear teal water can make memorable photographs. Keep your expectations in check, though. The water can be less clear after rain or in windy weather, and a reef that looks promising may not produce much animal life during your visit.

Drinks, Shade, and Time in the Water

After snorkeling, the crew provides bottled water, soda, and beer. These are simple inclusions, but they matter on a sunny half-day boat trip. There is no rum punch included on the shared charter, so bring your expectations down to cold beer, soda, and water rather than a full bar service.

The four-hour length is well judged for many people. You have time for a substantial snorkel and a beach stop without giving up an entire day. Families and couples can fit it into a larger St. Thomas schedule, and cruise visitors may find the shorter format easier to manage than a full-day sailing trip.

The time can feel divided differently from one outing to another. Some departures make two snorkel stops. Others combine one snorkel site with a beach visit. If the boat spends more time traveling because of conditions or distance, your water time may be shorter than expected.

You need to bring your own towel and sunscreen. Use reef-safe, non-aerosol sunscreen, and check the ingredients rather than relying only on the label. The crew is serious about protecting coral and sea life, and one commonly accepted option mentioned by the crew is Blue Lizard.

The Beach Stop at Hawksnest or Honeymoon Beach

After snorkeling, the boat may head to Hawksnest Bay or Honeymoon Beach at Caneel Bay. The exact beach depends on weather, sea conditions, and the captain’s plan. These beaches are known for white sand and clear blue water, giving you a chance to slow down after an active swim.

There is an important practical detail here: the boat may not be allowed to pull directly onto shore. At Honeymoon Beach, some people have had to swim about five minutes from the boat to the sand. Others stayed near the boat for more snorkeling, while some swam in for a drink at the beach snack bar.

That makes the stop more flexible, but it also makes it less suitable for anyone who cannot comfortably swim in open water. You should be ready to remain in the water or use the boat as your base. This is not a guaranteed walk-off beach landing.

Honeymoon Beach may also offer another chance to see turtles and fish around the seagrass and reef near the ranger station. Hawksnest can provide a classic St. John beach setting, though conditions can alter the plan. If reaching the beach is your top reason for booking, ask the crew at check-in how the day’s conditions may affect the landing.

The Value of $135 Per Person

At $135 per person, this is not the cheapest way to get into the water around St. Thomas. The price makes more sense when you compare it with what is included: about four hours on the water, a small group, a powerboat ride to St. John or nearby cays, snorkel equipment, water, soda, and beer.

The main value is the group size. Large boats may cost less per person, but they can feel crowded at the swim stops and slower when everyone is getting suited up. Here, you have a better chance of hearing the captain’s advice and getting a less crowded experience.

It is also a useful middle ground between a public beach and a private charter. You do not have to arrange a boat, navigate between islands, or rent all the equipment yourself. At the same time, you are sharing the outing with up to 11 other people, so the route and pace are not entirely yours.

The price is strongest for people who want both snorkeling and a quick look at St. John. It is less compelling if you only want a beach day, dislike boat motion, or expect a guaranteed turtle encounter. For a private trip, a custom route, or a full-day schedule, you would need a different product.

Who Will Enjoy This Trip Most

I would choose this trip if you want a compact outing with real time in the water and a smaller group. It fits couples, families with confident swimmers, and anyone who would rather avoid a large boat packed with people.

It also suits repeat visitors who have already spent time on St. Thomas beaches and want to see the nearby islands from the water. The captains often share stories about St. John and the surrounding islands, and the route can include views and coves you would not reach by road.

You should think twice if anyone in your party has trouble swimming, gets seasick easily, or needs a guaranteed beach landing. The boat may anchor in water too deep to touch bottom, and the beach portion may involve a swim. Young children under age two require a call before booking.

The trip runs in changing weather and requires moderate physical fitness. Poor conditions can lead to a new date, a different route, or cancellation. That flexibility protects the outing, but you should keep some room in your schedule if the weather forecast looks uncertain.

Booking Details That Matter

The tour begins and ends at The Shops at American Yacht Harbor, 6100 Red Hook Quarters, Red Hook Road, St. Thomas. Your confirmation arrives when you book, and the activity is offered with a mobile ticket.

Free cancellation is available up to 24 hours before the start time for a full refund. Cancellations or changes within 24 hours are not refunded. If poor weather cancels the trip, you can choose another date or receive a full refund. The same applies if the minimum number of people is not reached, although you may also be offered another experience.

Tips are not included. For good service, plan on about 15 to 20 percent for the captain and crew. Bring a towel, reef-safe sunscreen, a swimsuit, and an underwater camera if you have one.

Should You Book the MV Island Flyer Trip?

Book it if you want a half-day on the water, a small group, and the chance to combine St. John snorkeling with a beautiful beach stop. The strongest reasons are the limited number of people, the capable local captains, and the possibility of seeing much more than ordinary reef fish.

Go in knowing that the route changes, wildlife is never guaranteed, and the beach may require a swim from the boat. If those conditions suit you, $135 is a fair price for an active four-hour outing with equipment and drinks included. If you need easy shore access or a fully predictable itinerary, choose a land-based beach day instead.
