Will you be stopping on the island of St. Thomas in the Virgin Islands on your next cruise? Cruise ships love St. Thomas, and for good reason! There is so much to see and do in the Virgin Islands, even if you only have a couple of hours to explore.


Want to know a surprising fact? One of our most popular tours for cruise ship visitors isn’t a beach day. Not focusing your entire day on the beach on an island with many world-class beaches IS unusual. But here’s what people love to do on St. Thomas instead:

This tour is an incredible way to explore more beyond the beach. After all, on a cruise, you will be seeing almost an endless stream of beaches. This ecotour adds some variety to your vacation with an infusion of time in nature. This tour is also a great way to get active for the day—you will get to kayak, hike, AND snorkel. It’s not strenuous, but it is quite the adventure.

Your tour begins in the Mangrove Lagoon, conveniently located a short ride from the cruise ship ports. Here, you’ll meet your guides and have a briefing on the area. Then, you’ll board your two-person kayaks and paddle through the winding waterways of the mangroves. The Lagoon is a protected ecosystem that is home to a wide variety of plants and animals. Your guides will point out the local flora and fauna, and provide you with detailed information on the natural world and the islands’ history.


Cas Cay is an uninhabited cay just outside of the Mangrove Lagoon. After beaching your kayaks, you’ll have the opportunity to both snorkel and hike around the island with your guides. The cay is home to an army of hermit crabs, panoramic views, tide pools, and a volcanic blowhole that makes for some incredible photo ops.

After about 3 hours, you’ll return to the Mangrove Lagoon with amazing pictures and memories that those who just went to lay on the beach will envy!

The north shore of St. John in the U.S. Virgin Islands is one of those rare places that manages to feel both untouched and well-known. Stretching along the island’s Caribbean-facing coastline, this region is widely regarded as one of the most beautiful in the world—and it’s easy to see why. You can’t visit St. John without spending time on it. In fact, it’s probably the most popular reason why people visit St. John. ( Who among us hasn’t been lured into STJ dreaming by one of those iconic photos of Trunk Bay? ) However, there is so much to see and experience along the north shore. You likely will not be able to do it all on your first trip here. Here’s what to know about the north shore of St. John:

If you’ve been to St. John in the US Virgin Islands, you’ve likely encountered the wild donkeys around the island. Whether they approached you on the beach, strolled up to your Jeep’s window, or clip-clopped alongside you while shopping in Mongoose Junction, you were likely charmed by the presence of such a surprising farm animal on our little island. Because we’ve been posting a bunch of fun donkey videos lately over on our Facebook and Instagram accounts (if you’re not already following us, be sure to go and join in on the fun!), we thought we’d share a few fun details about the island’s donkey population.

The US Virgin Islands are a great place for both beginner and experienced snorkelers. The waters tend to be calm, clear, and warm year round, and there are many places where you can see an abundance of reef and marine life in relatively shallow waters. We love helping visitors experience the magic of the underwater world, and we have guided snorkeling tours and snorkel gear rentals available on all three islands: St. Thomas , St. John , and St. Croix . In order to best appreciate our waters and have a wonderful time while you’re “under the sea,” here are a few USVI snorkeling safety tips to keep in mind:

Here’s a hot take I have for the US Virgin Islands: Everyone should take a guided snorkel tour at least a couple of times, no matter how many times they’ve been snorkeling here before. I know, I know… you’ve already snorkeled here. Why would going with a guide change anything when you already know how to snorkel? Why do you need someone to accompany you when you already have a fish identification card and rented snorkel gear so you can go by yourself?
