MM = Mile Marker. The Keys are identified in Mile Markers. Key West is Mile Marker 0 and Key Largo is Mile Marker 106.
Key Largo (MM 106 to 91)
Shaded in places by tropical vegetation, a 15.5-mile paved trail currently runs by numerous businesses and parks. Side trips to John Pennekamp Coral Reef State Park, Key Largo Community Park and Harry Harris Park provide opportunities for recreation and relaxation along the way to Islamorada.
Islamorada (MM 91 to 71)
Islamorada has 20 miles of existing trail along US 1. The trail ends at the highway bridges through the Village and travelling between the islands in this area requires crossing over the US1 bridges. The trail ends at MM 71on Craig Key.
Park and Windley Key Fossil Reef Geological State Park are trailhead locations. Other state parks in the area are Indian Key Historic State Park, Lignumvitae Key Botanical State Park and San Pedro Underwater Archaeological Preserve State Park. The Channel 2 (MM 72) and Channel 5 (MM 70) historic bridges are popular for fishing.
Long Key (MM 71 to 63)
About 6 miles of trail connect the City of Layton to Long Key State Park and the Long Key Historic Bridge. The trail continues across Long Key Bridge. Tom’s Harbor Channel (MM 60) and Tom’s Harbor Cut (MM 62) historic bridges are popular fishing bridges which, in addition to the Long Key Bridge, have been retrofitted with cantilevered fishing platforms.
Marathon (MM 63 to 40)
An 11 mile trail runs from Grassy Key through Curry Hammock State Park to the Seven Mile Bridge at the southwest entrance to the City of Marathon. Knights Key, at MM 47, is a trailhead for the FKOHT and part of the old Seven Mile Historic Bridge that leads to the island of Pigeon Key and its museum, which features a rich collection of photographs and artifacts from the Flagler railroad era.
Lower Keys (MM 40 to 11)
the south end of the Seven Mile Bridge at MM 40, the trail traverses three historic bridges to Bahia Honda State Park, Spanish Harbor Historic Bridge and onto Big Pine Key, where there are trail segments on both sides of US1. From MM 29 to MM 26, trail exists between the islands but, at this time, travel between islands in this area requires use of some of the US1 bridges. A section of the trail at MM 16 connects Lower Sugarloaf Key to Big Coppitt Key, MM 10, crossing the five Saddlebunch Historic Bridges. Please be advised that a few fishing bridges in this area have been closed for safety purposes. They are the Ohio-Missouri, Ohio-Bahia Honda, Missouri-Little Duck, Lower Sugarloaf, and Niles.
These bridges are part of Henry Flagler’s Florida East Coast Railway built around the turn of the century. At older than 100 years of age, the bridges are no longer used for transportation purposes. The next closet bridge area for the public to fish from is on US 1 at MM 40, at the west end of the Seven Mile Bridge.
Key West (MM 10 to 0)
Trail extends from MM 10, Big Coppitt Key, across Rockland Channel Bridge 6 miles to Stock Island into the City of Key West. From Stock Island, at MM 4, the trail continues into downtown Key West where travel around the city by bicycle is already well established. In Key West, there are many historic and cultural points of interest to explore including Fort Zachary Taylor Historic State Park, Key West Botanical Garden, Bayview Park, Higgs Beach, and the famous monument marking the Southernmost Point in the continental United States.
