What to Expect at the History of Diving Museum in the Florida Keys

If you’re road-tripping through the Florida Keys and need a break from sunbathing, conch fritters, and key lime pie (hey, it happens), let me introduce you to one of the most unexpectedly awesome little spots in Islamorada: the History of Diving Museum.

Yes, you read that right. A diving museum. And before you assume it’s just a dusty collection of snorkels and wetsuits—trust me, it’s way cooler than that.

Plan Your Visit

The museum is located right off the Overseas Highway in Islamorada—perfect for a quick stop as you cruise between Key Largo and Key West. It’s open daily, and the admission is super reasonable (bonus: it’s air-conditioned, which is gold when you need a break from the Florida heat).

Address: 82990 Overseas Hwy, Islamorada, FL 33036.

Helpful Tips For Visiting The History of Diving Museum

• Expect to spend one to two hours exploring the museum.
• The museum has a free parking lot.
• The History of Diving Museum participates in the Museum for All program.
• There are many events and free presentations throughout the year. Check the calendar for dates.

Where Steampunk Meets the Sea

The moment you walk in, you’re greeted by what can only be described as an army of brass-and-copper helmet diving suits that look like they walked off the set of a vintage sci-fi film. These bad boys date back to the 1800s and were used for deep-sea diving back when “waterproof” was more a hope than a guarantee.

It’s like the museum took all the coolest parts of Jules Verne’s 20,000 Leagues Under the Sea and brought them to life—without the sea monsters (unless you count the eel sculptures).

A Deep Dive into Global History

The museum doesn’t just stick to Florida waters. The collection spans gear and diving history from all over the world—don’t miss the parade of nations, showcasing diving helmets from all over the world.

The exhibits are hands-on and interactive, so even if you’re traveling with kids or someone with a short attention span (no shade), there’s plenty to keep them entertained.

Myths & Marine Madness

One of the most fun parts? The museum dives into maritime folklore and pop culture, exploring the evolution of underwater exploration in movies, the legends tied to the sea, and early submarines that looked like floating barrels. You’ll find everything from treasure chests to tales of shipwrecks to jaw-dropping “wait, they really did that?!” diving stories.

Fun For The Whole Family

Be sure to kick off your visit at the Diving Museum by grabbing one of their scavenger hunts. They have different ones based on age. Kids get a fun souvenir upon completion of the scavenger hunt.

The museum also has hidden scuba divers, which can be tricky to find. We only found 5, and we missed many more out there.

The entire museum has plenty of interactive areas for kids of all ages. Try lifting a silver bar from the treasure room, sit inside a replica of Edmond Halley’s 1691 diving bell, and test how long you can hold your breath.

Don’t Sleep on the Gift Shop

Don’t skip the gift shop—it’s a treasure trove all on its own! The History of Diving Museum’s shop is packed with quirky, ocean-themed finds you won’t see anywhere else. Think vintage-style diving helmet miniatures, nautical decor, deep-sea creature plushies, and books that’ll make you want to become a maritime archaeologist. It’s the perfect place to pick up a fun souvenir or a totally unique gift for that ocean-obsessed friend.

TL;DR: The History of Diving Museum is a hidden gem with major cool factor. It’s weird, wonderful, and absolutely worth an hour or two of your Keys adventure. Whether you’re a marine history buff or just want to snap some sweet pics, dive in—you won’t regret it.
