Saint John is a Virgin Island in the Caribbean Sea and an unincorporated territory of the United States. It’s a popular destination for scuba divers, and it’s easy to see why.

Since the mid-50s, two-thirds of the island has been protected as the Virgin Islands National Park. From the white, sandy beach to the ancient petroglyphs of the Indigenous Taino people, the island is breathtaking. 

Gorgeous Accommodation

The island relies on tourism for its income, so you’ll find hundreds of villas, hotels, and resorts to stay in. There are also dozens of shops, restaurants, and eateries in Cruz Bay and Coral Bay that look out over the water. 

World-Class Dive Operators

Whether you’re diving for the first time or you’re an experienced diver, the waters around St John are world-class. There are numerous dive operators who can teach you to dive and help get you certified or take you out on some incredible excursions. 

Endless Activities

When you need a break from diving, there is plenty to do on the island. A sunset cruise is perfect for couples looking for a romantic getaway, while the nature trails around the island are great for hikers. 

Of course, you could also spend your visit lounging on the soft, sandy beaches and sipping cocktails at the resort bars. 

Vibrant Marine Life

The coral reefs around St John are part of the national park and are protected. Countless species call the reef home, including 90 known species of parrotfish. You’ll be able to spot them in the seagrass beds with their distinctive beak-like mouth and colorful scales. 

You might also be lucky enough to spot a  silver barracuda, damselfish, stingray, and even a green sea turtle or a hawksbill turtle.

Getting to St John

Saint John is a Virgin Island in the Caribbean Sea

St John doesn’t have an airport, so you can’t fly directly. However, the island is served by Cyril E. King Airport in Saint Thomas. 

Once you’ve flown into Saint Thomas, you’ll need to hitch a ride on a ferry at Red Hook, Charlotte Amalie, or Tortola. They run at different times throughout the day, so make sure to check the schedules. 

If you’re planning on bringing a car, you’ll need to book a spot on a barge. These run from Red Hook to Cruz Bay, operating hourly during daylight hours. 

Some rental companies allow their vehicles on the car ferry, but many don’t. Make sure you check with your rental company before making any plans. 

You don’t actually need a car when visiting Saint John. Taxis are widely available across the island, and there’s also a water taxi service to help you island hop. 

Finally, the VITRAN public bus service runs hourly on weekdays between Cruz Bay and Salt Pond Bay, giving you a cheap way to get around. 

The Best Scuba Diving Spots in St John

One of the best places for scuba diving in St John

There are almost a dozen top-rated scuba diving sites in St John that have everything from shipwrecks to massive caves. But if you’re short on time and want the best diving spots in St John, here are our top picks. 

Carvel Rock

Carvel Rock is home to hundreds of exotic birds, making it an interesting spot to visit. Underwater, you’ll find the rock covered in sponges and gorgonians, perfect for non-divers and snorkelers to explore. 

For more experienced divers, the north side of Carvel Rock drops below 80 feet, and it’s here you’ll see tarpon and stingrays feeding. 

Eagle Shoals

Over on the east side of the island is the quiet spot of Eagle Shoals. It’s filled with coral caves and deep channels to explore, rich with copper sweepers, jacks, and baitfish. 

If you’re hoping to spot manta rays or a shark, this is the best place to visit. It’s exposed to the open ocean on each side, giving you more opportunities to spot larger marine life. 

Eagle Shoals is also home to The Cathedral – a massive open chamber with different entry points. If you look up while submerged, it looks like a huge skylight high above. Because of its beauty, it’s a popular spot for underwater weddings. 


This mysterious spot is home to an abandoned underwater laboratory once used by NASA and the US Navy. Anchored 50 feet off the seafloor, the empty facility is an eery site and well worth a visit. 

You’ll find coral-encrusted tunnels and large caves, all hosting triggerfish, mackerel, tarpon, and squid. 

Congo Cay

Finally, Congo Cay is a popular spot for beginner divers going out on their first dive. There are plenty of shallow areas to practice with your scuba gear and a huge span of coral teeming with fish and marine life. 

There are also numerous grottos to explore if you’re feeling adventurous, and you might just spot a sea turtle or shark if you’re lucky. 

Which St John Dive Site Should You Choose?

The most well-known dive sites in St John are Congo Cay, Grass Cay, Arches of Tunnel, and Lovango Cay. 

But there are also dozens of other lesser-known dive sites less than half an hour from the main harbor. If you’re a divemaster and want to get off the beaten track, it’s best to ask local dive shops for their advice on the best spots – they’ll be happy to share their favorite places with experienced divers looking for adventure.

  • An introductory dive course in St John costs around $60 to $120, depending on the operator and dive site. 
  • If you’re already certified, two morning dives cost around $100. 
  • A night dive will cost around $100, and these are well worth the money.

Tips For Scuba Diving In St John

  • Don’t dive alone. Even if you’re an experienced diver, you should always have a buddy or instructor with you in case of emergencies.

  • Always make sure you have the right equipment when going out on a trip – you’ll be able to hire equipment from local dive shops.  
  • Wear a waterproof sunblock to protect your skin, but make sure it’s coral-safe to protect the fragile ecosystem.  
  • Never touch the coral, overturn rocks, or touch marine life. You’re always there to observe, not interfere in any way.
