Pinellas Trail, National Recreation Trail in Pinellas County, United States

The Fred Marquis Pinellas Trail is a paved rail trail running 47 miles (76 km) from Tarpon Springs south to St. Petersburg, through Palm Harbor, Dunedin, Clearwater, Largo, Seminole and Gulfport. Its grey asphalt surface, bordered by mown grass and low wooden fences, follows the corridor of the former Orange Belt Railway and Tampa and Gulf Coast Railroad.

The route originated from former railroad tracks used by the Atlantic Coast Line and Seaboard Air Line, which transported freight and passengers across the region for decades. When these lines merged into the Seaboard Coast Line in 1967, the abandoned tracks eventually became a public recreation pathway.

The pathway connects eight municipalities in Pinellas County, allowing residents to experience different local communities while exercising or traveling between towns.

Emergency assistance markers placed every 200 to 300 feet help first responders quickly locate anyone needing help along the route. The pathway is well-marked throughout, making it easy for visitors to navigate and maintain their bearings while traveling.

The trail follows two former rail corridors: the Orange Belt Railway from Tarpon Springs to Clearwater and the Tampa and Gulf Coast Railroad from Clearwater to St. Petersburg. The first 5 miles opened in December 1990 between John S. Taylor Park in Largo and Seminole City Park. The full loop is planned to reach 75 miles (121 km).
