Marathon Overview

The Islands of Marathon — The Heart of the Florida Keys (Mile Markers 63 to 40)

Called the boating and family destination of the Keys, Marathon includes Boot, Knights, Hog, Vaca, Stirrup, Crawl and Little Crawl keys, East and West Sister's Island, Deer and Fat Deer keys, Long Pine and Grassy keys. It incorporated as the city of Marathon in 1999.
Settlements on the islands of Marathon can be traced back to the early 1800s when Bahamians established tropical fruit farms and New England fishermen inhabited the region.
Crossing the shimmering waters south of Vaca Key is the Seven Mile Bridge, one of the longest segmental bridges in the world. The Old Seven Mile Bridge that runs parallel to the modern span was the jewel of the Florida Keys Over-Sea Railroad, completed in 1912, whose track stretched from mainland Florida throughout the Keys.
The spirit of this trestle's past can be found on Pigeon Key, the original headquarters and staging area for construction of the bridge. The historic island's museum contains artifacts from the Florida Keys railroad era, along with models, a video about the railroad, and antique postcards and photos depicting early life on Pigeon Key.
Throughout the region, environmental attractions provide visitors opportunities to swim with dolphins, “meet” sea turtles, explore hardwood hammocks and rainforests, stroll sandy beaches and enjoy an abundance of watersports.
World-class sport fishing can be found offshore at the reef and on the flats, along the bridges and in nearby Everglades National Park. Challenging the mighty tarpon or "Silver King of the Keys" near the bridges of Marathon is a test of strength, endurance and boating skill.
Snorkel and scuba dive excursions fulfill most divers' appetites. The beautiful underwater world at Sombrero Reef and the ghostly Thunderbolt shipwreck — named for its seagoing duty as a lightning target — are two of Marathon's best-known dive attractions.
Kayakers can paddle through the solitude of local mangrove-lined waters or explore around small, bird-inhabited islands offshore. Standup paddling and kiteboarding attract many devotees to the Marathon area.
Visitors can charter a fishing boat or recreational boat, play golf and tennis, take in the theater and eat at a variety of restaurants ranging from small cafés to funky waterfront seafood spots.
Marathon boasts comfortable resorts, luxury accommodations, waterside vacation homes, marinas, family-style attractions and the conveniences of a modern community, including a newly constructed hospital and high-tech library, all while retaining the relaxed charm of its roots as a 19th-century fishing village.
