Florida Keys – America’s Diving Capital
Florida is often hailed as the crown jewel of diving in the US. The Florida Keys, in particular, offer clear waters, coral reefs, and numerous wrecks including the USS Spiegel Grove in Key Largo. If you’re visiting the west coast of Florida, there are also romantic things to do in Bradenton, FL, making it perfect for couples who want a mix of underwater and above-ground romance.
John Pennekamp Coral Reef State Park is the first undersea park in the US, and it offers snorkelling and scuba diving options that cater to beginners and experts alike. The tropical marine life, vibrant corals, and crystal-clear water make it a must-visit.
Monterey Bay, California – Kelp Forest Diving
For a colder and more dramatic diving experience, head to Monterey Bay in California. The dense kelp forests create a surreal underwater environment teeming with sea otters, harbour seals, and giant sea bass. It’s a fantastic destination year-round, especially for those interested in marine biology.
While you’re in California, consider exploring things to do around Mt. Shasta for a mix of mountains and ocean escapes. Dive trips in Monterey often include access to the Point Lobos State Marine Reserve, which has some of the best visibility on the West Coast.
Channel Islands – Untouched Underwater Wilderness
Located off the Southern California coast, the Channel Islands offer some of the most pristine dive sites in the continental US. The marine life is abundant and diverse, with sea lions, lobsters, and schools of fish found in every cove and crevice. The volcanic origins of the islands make the underwater topography stunning.
Since the area is remote, it’s ideal for those seeking a quiet, immersive diving experience. There are guided diving charters that include camping on the islands, giving you a complete nature-centric escape.
Bonne Terre Mine, Missouri – A Dive into History
Looking for something truly unique? Dive into an old lead mine! The Bonne Terre Mine in Missouri offers one of the world’s largest freshwater diving resorts. You’ll swim through illuminated tunnels, around mining equipment, and down historic paths that haven’t changed in decades.
This site is especially suited to those interested in both diving and history. While it’s not for absolute beginners due to limited visibility and enclosed environments, experienced divers will find it to be an unforgettable excursion.
Lake Superior – Great Lakes Wreck Diving
If you’re intrigued by shipwrecks, head to Lake Superior, where the cold, fresh water has preserved wrecks for over a century. Sites like the wrecks in the Pictured Rocks National Lakeshore are accessible and well-documented, offering hauntingly beautiful underwater exploration.
These dives are typically done in the summer months due to icy conditions during the winter. They are best for dry suit certified divers, given the chilly temperatures. If you’re travelling across states, consider exploring fun things to do in the Quad Cities for adults while in the Midwest.
Hawaii – Volcanic Reefs and Pelagic Encounters
Hawaii is a diver’s paradise, featuring a mix of lava tubes, sea caves, and incredible pelagic life. From manta ray night dives in Kona to the lava-carved reefs off Lanai, Hawaii has something for every underwater adventurer. For those craving something offbeat, try a dive at the Molokini Crater, a partially submerged volcanic caldera teeming with fish and coral.
Each island has its diving highlights, so plan your trip to explore multiple islands. Make sure to check out accommodation options like those near Glass House Pomona for a blend of urban and natural getaways.
Cape Cod, Massachusetts – East Coast Exploration
Don’t overlook the East Coast when thinking about the best diving in the US. Cape Cod offers surprisingly rich marine biodiversity, shipwrecks, and reef systems. With proper guidance, you can explore WWII wrecks and natural reefs filled with Atlantic marine life.
