The best thing about this St. Thomas outing is its small-boat format. With no more than 12 people, you get a faster, friendlier ride to St. John and nearby cays instead of spending half the morning finding space on a packed catamaran. Captains such as Hillary, Glen, Mike, Dallas, Sammy, and Wallens are known for sharing local details and choosing stops based on sea conditions.

I like two things right away: the chance to see turtles, rays, squid, and reef fish, and the useful pairing of snorkeling with a beach stop. The main catch is simple but important: at some beaches, the boat cannot pull up to shore, so you may need to swim about five minutes to reach the sand.

Key points to know before you book

St Thomas~St John Snorkel, Swim & Beach Trip on MV Island Flyer - Key points to know before you book

  • Maximum of 12 people: This semi-private trip gives you more room and less waiting than a large-boat excursion.
  • Two water stops in about four hours: Stops may include Maho Bay, Christmas Cove, Lovango Cay, Hawksnest Bay, Honeymoon Beach, or nearby cays.
  • Strong wildlife potential: Turtles, nurse sharks, stingrays, eagle rays, barracuda, squid, starfish, and tropical fish have all been spotted.
  • Beach access may require swimming: Honeymoon Beach and other stops are not always reachable by boat directly onto the sand.
  • Drinks are included: You get bottled water, soda, and beer after snorkeling. Rum punch is not part of the shared charter.
  • Bring reef-safe sunscreen and a towel: Sunscreen must meet the crew’s environmental requirements, and towels are not supplied.

A small boat from Red Hook to St. John

You meet the captain and crew at the Seas the Day departure lounge at The Shops at American Yacht Harbor in Red Hook. The lounge is on the lower floor, immediately across from the entrance to B Dock. This is a useful location if you are staying in or near Red Hook, though parking can be tight. If you drive, allow time to look for a space, and check the ferry parking area if availability permits.

From the harbor, the boat heads toward St. John and the surrounding cays. The ride itself is part of the appeal. You are out in the open air, moving quickly between islands, with more time for swimming and less time tied to a dock.

The boat may be the 36-foot MV Island Flyer, a 36-foot Twin Vee, a 31-foot Wellcraft, or another similar vessel. The exact boat depends on availability, so you should not book this expecting one guaranteed hull. The important constant is the small capacity, with a maximum of 12 people on the trip.

That size changes the feel of the day. You can move around more easily, hear the captain, and get into the water without a long line. It also means the group’s pace matters. On a shared charter, you are spending the day with other people, so the stops and timing are set for the group rather than tailored entirely to you.

Choosing a snorkel stop around St. John

St Thomas~St John Snorkel, Swim & Beach Trip on MV Island Flyer - Choosing a snorkel stop around St. John

The first main stop is usually a snorkeling location around St. John or one of the nearby cays. Possible sites include Maho Bay, Trunk Bay, Christmas Cove, St. James Island, Lovango Cay, Mingo Cay, and Stevens Cay. The captain chooses according to wind, waves, visibility, and local conditions.

That flexibility is valuable in the Virgin Islands. A bay that looks calm from shore may have poor visibility, while a nearby cay may offer clearer water and better shelter. The tradeoff is that you cannot count on one named location every time.

Maho Bay

Maho Bay is one of the better-known spots for sea turtles, and several outings have produced close turtle sightings there. You may also see reef fish, rays, squid, and coral. One particularly useful detail is that the boat may anchor some distance from the shallow seagrass area, requiring a longer swim. One account described a swim of about 100 yards to reach the seagrass.

That distance is manageable for a confident swimmer, but it is not a minor detail for everyone. If you tire easily, are not comfortable swimming in open water, or are traveling with young children, ask the crew about the expected swim before entering the water.

Lovango Cay

Lovango Cay can offer calmer water and coral close to the boat. The snorkeling depth described on one outing was about 12 feet, which is comfortable for many people and gives you a good view of fish and reef life without needing to swim far down.

The area also benefits from coral restoration work near Lovango Resort. That does not guarantee a particular animal sighting, but it adds meaning to the stop. You are seeing a living reef system that local marine workers are trying to protect and rebuild.

Christmas Cove and the smaller cays

Christmas Cove, Mingo Cay, Stevens Cay, and St. James Island may be used when conditions suit. These locations can feel less tied to a conventional beach day. You are stopping in open water near small islands or reefs, often with fewer boats in sight.

The attraction is space and variety. The limitation is that sea life is wild. One stop may produce turtles and rays, while another may seem quiet. The crew can improve your odds by choosing good water, but nobody can promise a turtle, shark, or ray on a particular morning.

What you might see beneath the surface

St Thomas~St John Snorkel, Swim & Beach Trip on MV Island Flyer - What you might see beneath the surface

The listed fish include snapper, parrotfish, sturgeonfish, squirrelfish, and other tropical species. The sightings described on recent trips have also included nurse sharks, barracuda, spotted eagle rays, stingrays, squid, starfish, jellyfish, and sea turtles.

Nurse sharks in this area are generally treated as calm animals, but you should still follow the captain’s instructions and give all wildlife room. The same applies to turtles. The best encounter is one where the animal can continue feeding or swimming without being chased.

Snorkel gear is supplied. The equipment has been described as being in excellent condition, but fit varies from person to person. Tell the crew quickly if your mask leaks or your fins do not fit. A well-sealed mask matters more than fancy equipment, especially when the boat is moving between several sites.

You should bring an underwater camera if you have one. Turtle sightings and clear coral scenes can be memorable, but the tour does not state that photography equipment is supplied. Use a secure strap and keep your attention on the water rather than spending the whole stop looking through a screen.

The beach stop, Hawksnest Bay or Honeymoon Beach

St Thomas~St John Snorkel, Swim & Beach Trip on MV Island Flyer - The beach stop, Hawksnest Bay or Honeymoon Beach

After snorkeling, the boat usually takes you to Hawksnest Bay or Honeymoon Beach at Caneel Bay, with the final choice depending on weather and sea conditions. These beaches offer pale sand and clear blue water, and the stop gives your day a different rhythm after the reef time.

Honeymoon Beach comes with a practical warning. The boat may not be allowed to land directly on the beach, so you could need to swim roughly five minutes from the boat to shore. The water beneath the boat may be about 25 to 35 feet deep, while the swim toward the sand becomes shallower.

You can choose to swim to the beach or remain near the boat, depending on the captain’s instructions and your comfort. Some people use the beach stop for sand and a snack-bar visit, while others continue snorkeling. This flexibility is helpful, but the stop is not the same as being dropped at a beach with an easy dry walk from the boat.

Hawksnest has the same general appeal: white sand, clear water, and a chance to stretch out after snorkeling. The beach selection is weather dependent, so consider the beach portion a flexible bonus rather than a guaranteed visit to one exact bay.

Drinks, shade, and the pace of the day

St Thomas~St John Snorkel, Swim & Beach Trip on MV Island Flyer - Drinks, shade, and the pace of the day

The price includes bottled water, soda, and beer. Drinks are especially welcome after an hour in salt water and sun. The crew typically brings them out after snorkeling, giving you a relaxed break before or during the beach portion.

Do not expect rum punch on the shared charter. Beer, soda, and water are the included choices. You should also bring your own towel and sunscreen. The company requests non-aerosol, reef-safe sunscreen, and the crew may check the ingredients. Products such as Blue Lizard were specifically identified as acceptable, though you should still confirm your own sunscreen before the trip.

Several boats offer covered areas, which help during the ride and provide relief from the sun. Still, this is a four-hour outdoor activity. Wear a swimsuit, protect your shoulders, and keep valuables to a minimum. The information does not specify a storage system, so avoid bringing anything you would worry about getting wet.

The pace is active but not extreme. You board, ride to the first stop, snorkel, move to a second location, and return to Red Hook. You need a moderate level of physical fitness, comfort around open water, and enough swimming ability for a possible beach swim.

Why the four-hour length works

St Thomas~St John Snorkel, Swim & Beach Trip on MV Island Flyer - Why the four-hour length works

Four hours is a smart middle ground for this kind of outing. You get enough time to reach St. John, enjoy two locations, and return without giving up the entire day. That makes it easier to combine with dinner, shopping, or another activity in Red Hook.

The limit is that this is not a full-day charter. You will not have endless time at each site, and the crew must keep an eye on the return schedule. If you want long, unhurried time on one reef, a private charter may suit you better. If you want a compact introduction to the waters around St. Thomas and St. John, four hours is enough to make the trip worthwhile.

The boat normally visits two locations, though one outing included three snorkeling spots. Do not count on three every time. The official plan is built around two stops, and that is the more realistic expectation.

Captain-led local knowledge

St Thomas~St John Snorkel, Swim & Beach Trip on MV Island Flyer - Captain-led local knowledge

The captain can shape the quality of the day. Captains named in the trip information and feedback include Hillary, Glen, Mike, Dallas, Sammy, Wallens, and Montana. Their role is more than steering. They choose the route, explain the surrounding islands, help with gear, and watch conditions while you are in the water.

Hillary has been praised for finding good snorkeling areas, including spots with turtles and squid. Glen has been associated with sightings of turtles, rays, starfish, and many fish. Mike has taken people to locations where nurse sharks appeared, while Wallens has been noted for finding Maho Bay and a quieter spot between two cays.

Those examples show the advantage of a small crew-led outing: the captain can speak with you directly and adjust the day within the limits of weather and park rules. You should still keep expectations realistic. A captain can search good habitat, but wild animals may not appear, and water clarity can change quickly.

Is $135 a fair price?

St Thomas~St John Snorkel, Swim & Beach Trip on MV Island Flyer - Is $135 a fair price?

At $135 per person, this is not the cheapest way to reach a beach or snorkel from St. Thomas. You are paying for a boat ride to St. John and nearby cays, supplied snorkel equipment, captain and crew service, bottled water, soda, beer, and a small group.

The value is strongest if you care about avoiding a crowded vessel. A maximum of 12 people gives you a more personal setup than a large excursion boat, and the boat can move between sites without the feel of a floating crowd. The included drinks also keep small costs from adding up during the morning.

The value is weaker if your main goal is simply to sit on a beach. You may need to swim to shore, and the beach time is only one part of the four-hour outing. Likewise, if you are not comfortable in open water, you may not use enough of the snorkeling portion to justify the price.

For a family or couple seeking a half-day on the water, I think the price is reasonable, especially when the group is close to the 12-person limit and the captain finds two good sites. If the boat fills, the trip remains small by excursion standards, but it is still a shared charter rather than a private cruise.

Who should book this trip

I would choose this trip if you want:

  • A small group rather than a large catamaran
  • A chance to snorkel in more than one area
  • A quick visit to St. John from St. Thomas
  • A good possibility of seeing turtles and other reef life
  • A beach stop combined with time in the water
  • A captain who can change locations when conditions shift

I would think twice if you need a dry, easy step from boat to beach. You should also reconsider if you are uncomfortable with open-water swimming, cannot manage a possible 100-yard swim at Maho Bay, or want a guaranteed visit to one specific location.

Children under two require a phone call before booking. The activity is near public transportation, and confirmation is provided when you book. The boat returns to the same American Yacht Harbor meeting point.

Free cancellation is available if you cancel at least 24 hours before the start time. Changes or cancellations inside that 24-hour window are not refunded. Bad weather can lead to a different date or a full refund, and the company also requires a minimum number of people, so a trip may be rescheduled or refunded if that minimum is not reached.

My call: a strong half-day on the water

I would book this excursion for the small group, flexible snorkel stops, and strong chance of sea-life sightings. The captains have repeatedly been singled out for friendly service, local information, and calm handling of windy conditions. The combination of St. John scenery, coral reefs, turtles, and a beach stop gives you more variety than a simple shore snorkel.

Go in knowing that the exact boat and stops can change. Bring reef-safe sunscreen, a towel, and confidence in the water. If swimming from the boat to a beach sounds fine, this is a well-priced way to spend four hours around St. Thomas and St. John without being packed onto a big boat.
