Egmont Key is an uninhabited barrier island at the mouth of Tampa Bay accessible only by boat. It features partially submerged Civil War era battery ruins that are extraordinary to snorkel around and jump from, a lighthouse dating to 1848, free-roaming gopher tortoises, and sea turtle nesting beaches. Conditions can be rough at the mouth of the bay — Captain Keith assesses the water before heading out. Wayward Key Tours departs from Maximo Park in St. Petersburg for Egmont Key charters.

Egmont Key Florida Snorkeling History and How to Get There

Egmont Key is one of the most unique and historically rich destinations accessible by private boat charter from St. Petersburg. The island sits at the mouth of Tampa Bay where the bay meets the Gulf of Mexico — and beneath the surface around its shores lie the remains of Civil War era military batteries that make for extraordinary snorkeling unlike anything else on Florida’s Gulf Coast. Wayward Key Tours offers private charters to Egmont Key departing from Maximo Park in St. Petersburg.

What is Egmont Key?

Egmont Key is a small uninhabited barrier island and National Wildlife Refuge located at the southern tip of Tampa Bay, approximately 3 miles west of Fort De Soto Park. The island has a rich military history — it served as a base during the Spanish-American War, housed a Union garrison during the Civil War, and later became a Coast Guard station. The island’s lighthouse, built in 1848, is one of the oldest on Florida’s Gulf Coast and still operates today.

What makes Egmont Key truly special for boaters is what’s both above and below the water — crumbling brick battery ruins from the wartime era sit at the island’s edge, partially submerged, creating a surreal landscape where history meets the Gulf.

Snorkeling at Egmont Key

Snorkeling around Egmont Key is a one-of-a-kind experience on Florida’s Gulf Coast. The partially submerged military battery ruins create an underwater structure unlike anything you’ll find at a typical snorkeling spot — brick walls, archways, and foundations now colonized by marine life, all in relatively shallow, clear water. Rays, fish, and sea turtles are regularly spotted around and above the ruins.

Guests who are comfortable in the water also jump from the ruins — a feature that makes Egmont Key a genuinely exhilarating stop rather than just a passive snorkeling experience. The combination of history, wildlife, and the sheer strangeness of swimming through a submerged Civil War fort makes this one of the most memorable stops in the entire Wayward Key Tours charter area.

Wayward Key Tours provides snorkeling gear for every guest — mask, snorkel, and fins are included.

How rough can Egmont Key get?

Egmont Key sits at the mouth of Tampa Bay where bay and Gulf currents converge — and conditions there can be significantly different from the calmer inshore waters guests experience earlier in a charter. On the wrong day wind, tide, and current can combine to make the water choppy and uncomfortable for snorkeling.

Captain Keith assesses conditions before heading to Egmont Key on every charter. If the water isn’t right for a safe and enjoyable experience he’ll either adjust the timing around the tide or navigate to an alternative snorkeling location. This kind of real-time local knowledge is exactly why an experienced captain matters — conditions at Egmont Key can change quickly and knowing when to go and when to wait is something that only comes from extensive time on these specific waters.

The wildlife of Egmont Key

Beyond what you’ll see underwater Egmont Key is a designated National Wildlife Refuge and the island itself is rich with wildlife.

Gopher tortoises

Egmont Key has a thriving population of free-roaming gopher tortoises on the island’s interior. Encountering one of these ancient-looking animals on a walk along the island is a highlight for many guests, especially children.

Sea turtles

Egmont Key is an active sea turtle nesting beach. Loggerhead and green sea turtles nest on the island’s beaches seasonally and are frequently spotted in the water around the island.

Shorebirds

Ospreys, brown pelicans, herons, and a variety of shorebirds nest and feed around the island year-round. The undisturbed nature of the refuge means wildlife is abundant and relatively unafraid of visitors.

The Egmont Key lighthouse

The Egmont Key lighthouse was built in 1848 and is one of the oldest standing lighthouses on Florida’s Gulf Coast. The current structure replaced an earlier lighthouse destroyed by a hurricane. The lighthouse still operates as an active aid to navigation. It’s visible from the water on approach and makes for a striking backdrop on the island.

How to get to Egmont Key

Egmont Key is accessible only by boat — there is no road access and no public ferry service. The island is approximately 45-60 minutes by private charter from Maximo Park in St. Petersburg depending on conditions. Wayward Key Tours departs exclusively from Maximo Park in St. Petersburg for Egmont Key charters — the St. Petersburg departure point puts you significantly closer to the mouth of the bay than departing from Clearwater.

The 4-hour Full-Day Charter is strongly recommended for Egmont Key. The travel time to the island combined with meaningful time for snorkeling, exploring the ruins, and wildlife watching requires the extra hours. A 2.5-hour charter doesn’t leave enough time to make the trip worthwhile.

What to bring for an Egmont Key charter

• Reef-safe sunscreen — strong sun at the mouth of the bay with no shade on the island
• Water shoes — the island terrain and ruins are uneven
• A light layer for the boat ride — it can be breezy at the mouth of the bay
• Plenty of water and snacks
• An underwater camera or GoPro — the ruins below the surface are genuinely worth filming
• Curiosity — there’s a lot of history to take in above and below the waterline
