Seven Mile Bridge
There are two bridges in this location. The modern bridge is open to vehicular traffic; the older one only to pedestrians and cyclists. The older bridge, originally known as the Knights Key-Pigeon Key-Moser Channel-Pacet Channel Bridge, was constructed from 1909 to 1912 under the direction of Henry Flagler and Clarence S. Coe as part of the Florida East Coast Railway's Key West Extension, also known as the Overseas Railroad.
Dolphin Research Center (Grassy Key)
The Dolphin Research Center is a dolphinarium on Grassy Key, Florida. The 90,000-square-foot series of saltwater lagoons carved out of the shoreline is home to a family of dolphins and California sea lions. It features experiences where visitors can learn about marine mammals and the environment and also swim with, hand-signal, or enjoy other interactive programs with the dolphins.
Sombrero Beach
Sombrero Beach is a beautiful park and sandy beach. In 2001 the City redeveloped Sombrero Beach to include total handicap accessibility. A lovely sandy beach on the Atlantic Ocean frames a shady park with picnic pavilions, volleyball courts, restrooms and showers.

Sombrero Beach is a turtle nesting beach. From April through October it is not unusual to have Loggerhead Turtles (primarily) coming on to the beach at night to lay their eggs. During active turtle nesting season the City limits human activities in the vicinity of active turtle nest establishments. Turtle nest areas typically represents less than 10% of the available beach area. The remainder of the beach is open for our visitors and residents to enjoy. The City regularly surveys the beach for new turtle nesting. If you are interested in assisting the City in preserving the turtle population as a turtle surveyor, please do not hesitate to contact the City. F.D.E.P. holds classes in February or March every year to be a state certified surveyor. The City then schedules all of the surveyors for their day to walk the beach. Walking the beach first thing in the morning looking for turtle nests is an awesome experience.

Sombrero Reef
Sombrero Reef is one of the largest and surely the most magnificent coral reefs in the Middle Keys, home to some of the best spur and groove reef formations in all the Keys. The amount of coral is breath-taking. As soon as you descend, gorgonians, brain, finger and lettuce corals can be seen. Schools of colorful tropicals, southern stingrays and nurse sharks make their home on this reef. Large barracuda hang out by the lighthouse structure. The coral limestone has an "Arch" which is large enough to swim through.
Fishing Charters & Tours
With a name worthy of the area’s unbeatable angling, Marathon fishing has a way of always making you want to stay out longer, and fishing can be as productive in 10 feet of water as it can be in 1,000. The historic Bahia Honda and Seven Mile bridges are often named by Tarpon addicts as having some of the best fishing in the keys, and fishing in Marathon certainly isn’t limited to dropping lines under bridges. The elaborate network of patch reefs and reef systems means that if you’re fishing in the Florida keys you’re almost guaranteed to land something special. Year-round populations of Spanish Mackerel, Barracuda, Snapper, and Grouper, are joined by as many visitors below the water as above, and if you head out past the deep sea wrecks and into the blue waters, Marathon charter fishing can see you battling anything from Wahoo and Mahi to monster Tuna, massive Marlin, and even Swordfish. So let the crowds all squash onto that boat to Key West, you have everything you need right here, and from fly fishing fights to usurp the Silver King to deep water adventures plunging lines a quarter-mile into the abyss, it’s guaranteed to be marathon!
Scuba & Snorkeling
Marathon welcomes all divers, from a first time breathing underwater to professionals that have mastered the art. With our prime location in the middle of the beautiful Florida Keys, Marathon hosts a large section of the 3rd largest barrier reef in the world. Our Marathon boats have over 30 different dive sites to choose from. So, why dive anywhere else? Have family members that don't want to dive, but like to fish? Whether you have a week to spend on vacation, or only a few hours, we can entertain you with lifelong, funfilled memories. Marathon is quiet, uncrowded, and great for families.
