Getting There And Accommodations

Hewanorra is the airport of choice for international flights.

For some island-hopping, George F.L. Charles Airport (SLU) will be your airport of choice. Flights to various islands include Curacao, St. Maarten, St. Kitts, Barbados, Antigua and St. Vincent. Hey! Why stay on just one island, when you can hit a couple! But there is plenty about St. Lucia to keep you there.

For accommodations on St. Lucia, there are many to choose from. These choices include several adults-only all-inclusive Sandal resorts and the stunning Jade Mountain resort, as well as family friendly resorts such as Coconut Bay, Coco Palm and Sugar Beach.

Remember, when traveling for diving, consider the following factors: proximity to dive sites; dive packages offered; amenities; and (of course) your budget. For example, Sandals Halcyon Beach is a popular choice, offering scuba diving with up to two tanks per day included in your stay, but is adults only and may not be in everyone’s budget.

Turtle Reef

One of St. Lucia’s most captivating dive sites is Turtle Reef, a dramatic underwater landscape that’s teeming with marine life, albeit not many turtles (Go figure). This unique dive spot located on the islands Southwest side features a plateau adorned with barrel sponges and pillar and organ pipe coral, before dropping off into a sheer wall.

As you embark on your dive look for the smaller reef fish taking refuge near the cliff face, as well as schools of barracuda lurking nearby. This dive site provides a truly mesmerizing experience, as you glide past sea whips, soft corals, and huge brain corals that cover the reef.

The dive starts at a depth of about 40ft and can go beyond recitational limits, making it suitable for those with experience in buoyancy control.

Shipwrecks Lesleen M and Daini Koyomaru

St. Lucia’s underwater realm is not only home to vibrant coral reefs and marine life, but also fascinating shipwrecks that have become artificial reefs. Two popular wreck dive sites are the Lesleen M and the Daini Koyomaru, with each offering a unique and captivating experience for wreck diving enthusiasts.

St. Lucia has a few nice wrecks to explore, like the Lesleen M pictured above.

At Anse La Raye Wall, located just about in the middle of the West side of the island, lies the wreck of the Lesleen M. This 165-foot freighter was purposefully sunk in October 1986 and rests at a depth of about 65ft. It is now home to a variety of marine life, including lobster, moray eels and frogfish.

The Daini Koyomaru wreck, lies just a little south of the Lesleen M. This old Japanese minesweeper was sunk on purpose in 1996 to also create an acritical reef. She is 246ft long and 82ft high. As she sits in about 108ft of water, her top is just about 26ft from the surface. This wreck offers the chance to encounter turtles, barracudas, angelfish, and moray eels.

Anse Chastanet Reef

Anse Chastanet Reef is a shallow dive site known for its abundance of macro marine life, making it a dream destination for underwater photographers and critter enthusiasts alike.

Named after one of the film locations of Superman II, Superman’s Flight is a thrilling dive site with moderate currents and clear waters. It is perfect for experienced drift divers seeking an exhilarating underwater adventure!

Heading up North there are some good sites as well including Saline Point, Smuggler’s Cove and the eerily named Bone Yard…Boooo!!

Saline Point

Let’s start with the most Northerly dive site on St. Lucia, Saline Point. Located off of LeSport Hotel with depths between 20ft to 60ft, this is an ideal spot for all level of divers and snorkelers.

There is literally an explosion of color on Saline Point with the various marine life swimming among the hard and soft coral and sponges. Divers can find here various rays and eels as well as pufferfish, scorpionfish and grunts. Beach entry is possible at this site as well.

Smuggler’s Cove

Just a little South of Saline Point is another nice easy dive site that can be done either by shore diving, or from a boat. Smuggler’s Cove is one of St. Lucia’s most beautiful and secluded beaches. Maximum depth is about 40ft and there are trenches and shelves to explore all over this site.

At Smuggler’s Cove you can typically see trumpetfish, lobster, squid and the very cool looking flying gurnard.

Bone Yard

Make no bones about it, you will want to add Bone Yard to your itinerary if hitting St. Lucia’s Northern dive sites. Located by Castries Harbor, are the remains of an old WW II ship rumored to have been torpedoed. There also appears to be the wing of an airplane that was perhaps shot down during the conflict.

outside of the wreck remains there are also nice soft coral formations and large barrel sponges, with a variety of marine life swimming about.

Other Activities

If you’re looking for alternative ways to enjoy the beauty of St. Lucia, there are plenty of other activities to join in on in addition to the great diving. Even if you’re not a scuba diver (why would you not be a scuba diver?!), you can still experience the captivating wonders of St. Lucia and its waters.

The Piton Mountains

The amazing Piton Mountains are a UNESCO World Heritage Site and is the image that first comes to mind in many when thinking of St. Lucia.

The pitons are absolutely breathtaking.

Made up of Gros Piton (2,619ft) and Petit Piton (2,461ft), travelers can take in these natural wonders by boat, land and air. Keep in mind that the narrower Petit Piton is not usually hiked, but the wider Gros Piton is well marked for hikers. The Trail on Gros is a little over three miles long and is designated as “challenging” taking a total of between 6 to 12 hours to complete. Whichever way you decide to explore, don’t miss the Pitons!

ATV And Horseback Tours

Looking for a cool way to explore the island, then an ATV tour may be what you’re looking for. Hop on your all-terrain vehicle and follow your guide through forested paths to see the rural side of St. Lucia. Along the way you’ll see beaches, plantations and historical sites. A great way to spend a few hours of adventure!

Perhaps you’d like to go a little slower, then you can take a tour by horseback to a beach and right into the warm tropical waters.

Snorkeling is a great activity if you want to see some of the island’s vibrant marine life without diving too deep below the surface. Anse Chastanet Beach and Anse Cochon Beach are top spots for snorkeling, offering a diverse array of marine life to discover, including frogfish, batfish, turtles, seahorses, scorpionfish, shrimp, eels, squid, and octopus.


If you’re looking to take your snorkeling to the next level, then you might want to try SNUBA. On SNUBA you’ll have a regulator connected to an air hose that leads to your compressor floating above. This allows you to not have to surface to get your air and you can remain down below, approximately 20ft maximum, up-close and personal with the marine life.

If you don’t want to worry about keeping a regulator in you mouth, then you can try a Sea Trek Adventure where you wear a diving helmet as you walk along the bottom of ocean.

For those who prefer to stay above the water, kayaking and paddle boarding provide a unique way to explore St. Lucia’s breathtaking coastline. These activities offer a different perspective of the island’s natural wonders, allowing you to glide along the water’s surface and take in the beauty of St. Lucia from a new angle.

Guided tours are available for both kayaking and paddle boarding, giving you the chance to learn more about the island’s history and ecology while enjoying a fun and active water adventure.
