Where to Snorkel in Key West: A Local’s Guide to the Best Spots

Key West, Florida is famous for more than just its laid-back vibes and stunning sunsets—beneath the surface lies an underwater world filled with vibrant coral, tropical fish, and clear, warm waters that invite you to dive in. Whether you're a first-time snorkeler or a seasoned explorer, there’s no better way to discover this island paradise than by slipping on a mask and heading beneath the waves.

At Conch ‘N Around, we specialize in helping visitors experience the best snorkeling Key West has to offer—by boat, by sandbar, or both. Here’s our local guide to the top spots and what to expect on your snorkeling adventure.

The Florida Keys National Marine Sanctuary

One of the most iconic places to snorkel in Key West, this federally protected area is home to the Florida Reef Tract—the third-largest coral reef system in the world. Just a short ride offshore, you’ll find healthy coral formations, swaying sea fans, and countless species of colorful fish. It's a favorite for both beginners and experienced snorkelers.

Expect to see:

• Parrotfish, angelfish, and wrasses

• Sea turtles gliding past coral heads

• Occasional stingrays and nurse sharks

Sand Key Lighthouse Reef

A true local favorite, Sand Key Lighthouse Reef offers some of the clearest waters around Key West. Located about seven miles offshore, the shallow depth and excellent visibility make it ideal for beginners and families.

What makes it special:

• Historic lighthouse backdrop

• Shallow reef with rich marine biodiversity

• Gentle currents and calm waters

Western Sambo Reef

Western Sambo is part of a larger ecological reserve, known for having some of the healthiest coral in the region. It’s a bit less trafficked, which means more marine life and a quieter, more serene experience.

Highlights include:

• Large brain coral formations

• Moray eels, lobsters, and schools of blue tang

• Excellent photo opportunities underwater

Snorkeling at the Sandbars

For something unique, combine your snorkeling trip with a visit to one of Key West’s famous shallow sandbars. These soft, white-sand patches rise above the sea during low tide and are perfect for relaxing between snorkeling sessions.

What you’ll discover:

• Starfish, sand dollars, and tiny reef fish

• Calm, ankle-to-waist deep water

• Great for kids and non-swimmers

At Conch 'N Around, our private and group charters let you explore these sandbars with ease, turning your day into a perfect mix of adventure and leisure.
