If you’re planning a trip to the US Virgin Islands and trying to figure out where to start, you’re not alone. St. Thomas and St. John come up in just about every conversation people have when they’re booking a Caribbean getaway, and for good reason. Both islands are stunning. Both have their own feel. And both are worth your time. The real question is how you want to experience them.
At Sonic Charters, we run private boat charters out of St. Thomas, and we take guests to St. John and across to the British Virgin Islands regularly. We’ve watched people fall in love with both islands, and we’ve also watched people wish they’d spent their time differently. So if you’re trying to decide where to start, here’s an honest look at what each island offers and how a private charter fits into the picture.
What St. Thomas Brings to the Table
St. Thomas is the most developed of the US Virgin Islands, and that’s both its appeal and its limitation, depending on what you’re after. Charlotte Amalie, the main port, has world-class shopping, a wide range of restaurants, and plenty of nightlife. The beaches are beautiful, the infrastructure is solid, and getting around is easy. For first-time visitors who want a soft landing in the Caribbean, St. Thomas delivers.
It’s also where Sonic Charters is based. That matters because St. Thomas is really the launching point for everything in this region. You can be anchored off a quiet BVI cay within a few hours. You can be snorkeling at the Indians or Coral Bay before lunch. The location puts you within easy reach of some of the best water in the Caribbean, and a private charter is how you actually get to it.
What Makes St. John Different
St. John is only about four miles from St. Thomas by water, but it feels like a different world. About two-thirds of the island is protected national park land, which means no large resorts, no sprawl, and a quieter pace that some travelers specifically go looking for. Trunk Bay is one of the most photographed beaches in the Caribbean. Cinnamon Bay has a campground right on the water. The hiking trails through the national park offer views that are genuinely hard to find anywhere else in the region.
Coral Bay, on the east side of the island, has a small community feel with local restaurants and a laid-back atmosphere that draws people back year after year. If St. Thomas is for people who want convenience, St. John is for people who want the Caribbean to feel a little more untouched.
The catch is that St. John has no airport and limited ferry access from certain points. A lot of travelers end up visiting St. John as a day trip from St. Thomas, which is where a private charter starts to make a lot of sense. You’re not waiting for a scheduled ferry, you’re not stuck on someone else’s timeline, and you get to pick where you stop along the way.
The Snorkeling Question
People ask us constantly where the better snorkeling is. The honest answer is that the best snorkeling in this area isn’t at either island’s beach, it’s in the water between and around them.
Waterlemon Cay, just off the north shore of St. John, is one of the top snorkeling spots in the entire Caribbean. The reef is healthy, the visibility is usually excellent, and you’ll see sea turtles there regularly. Haulover Bay on St. John’s east end is another spot that most tourists miss entirely because there’s no easy way to get there without a boat.
When guests book a private charter with us, snorkeling stops are always part of the conversation. We can plan the day around conditions and what you want to see rather than following a preset route. If you want to anchor at three different spots along the St. John coastline, we can do that. If you want to combine a stop at St. John with a run out to Norman Island in the BVI, that’s on the table too.
Why a Custom Itinerary Changes Everything
The thing about trying to choose between St. John and St. Thomas is that you don’t really have to. They’re so close together that with the right charter, you can experience both in a single day and still have time to drift into the BVI if conditions are right.
A typical private charter day from St. Thomas with Sonic Charters might look something like this: you board in the morning, we head east along the southern coast with St. John’s hills coming into view, we anchor at a snorkeling spot, then move along the coastline to a beach for lunch, and depending on what you want to do, we can push out toward the BVI or loop back through the channel. It’s a day on the water, not a shuttle from one tourist stop to the next.
The difference between a group ferry and a private charter isn’t just comfort, though the boats are certainly nicer. It’s that the day actually belongs to you. If someone in your group wants to stay in the water longer at a particular spot, we stay. If the wind shifts and there’s a better anchorage nearby, we go there instead. That flexibility is something you can’t get on any scheduled service.
So Which Island Should You Start With?
Here’s a practical way to think about it. If you’re staying in St. Thomas, use it as your base and get out on the water from there. St. John is an easy run from St. Thomas by boat and you’ll see more of it by approaching from the water than you ever would arriving by ferry to Cruz Bay and renting a car.
If your trip is specifically about nature, hiking, and a slower pace, consider staying in St. John and doing a charter day out to the BVI or back toward St. Thomas. The island has enough to keep you busy on its own, but the water around it is where the real magic happens.
Either way, plan a day on the water. The USVI and BVI together form one of the most extraordinary sailing grounds in the world. Seeing it from a beach chair is one thing. Seeing it from the bow of a boat with the islands spread out around you is another experience entirely.
Frequently Asked Questions
Can I visit St. John as a day trip from St. Thomas?
Yes, and it’s one of the most popular ways to do it. The ferry from Red Hook takes about 20 minutes, but a private charter lets you approach St. John from the water, stop at snorkeling spots along the way, and build the day around what you actually want to do rather than ferry schedules.
What is the best snorkeling near St. John?
Waterlemon Cay is widely considered the best snorkeling spot in the US Virgin Islands, with healthy coral, abundant fish, and regular sea turtle sightings. Haulover Bay and the waters off Trunk Bay are also excellent. Most of these spots are best accessed by boat.
Does Sonic Charters go to the BVI from St. Thomas?
Yes. Sonic Charters runs private charters from St. Thomas to the British Virgin Islands regularly. The BVI requires a passport and customs clearance, so you’ll want to plan ahead, but the trip is absolutely worth it. Norman Island, the Baths at Virgin Gorda, and Jost Van Dyke are all reachable on a day charter.
How far is St. John from St. Thomas by boat?
About four miles separates the two islands at their closest points. By charter boat, you’re looking at a short run of 20 to 30 minutes, depending on speed and sea conditions. It’s close enough to make St. John an easy addition to any charter day.
What should I bring on a private charter in the USVI?
Sunscreen, a hat, reef-safe sunscreen if you plan to snorkel, water shoes, a light layer for the wind, and a dry bag for your phone and valuables. If you’re heading to the BVI, bring your passport. Sonic Charters will take care of the rest.
Is a private charter worth it compared to a group tour?
For most travelers, yes. Private charters cost more upfront, but the experience is completely different. You set the itinerary, choose your stops, travel with your own group, and move at your own pace. For families, couples, or small groups, the value is hard to argue with once you’ve done it.
