Tallahassee-St. Marks Historic Railroad Trail State Park, Rail trail and state park in Leon County, United States.

The Tallahassee–St. Marks Historic Railroad State Trail is a 16-mile (26 km) paved rail trail built on the bed of the Tallahassee Railroad, running from Tallahassee south to St. Marks, where it ends near the confluence of the St. Marks and Wakulla rivers. South of US 98 it forms part of the Florida National Scenic Trail, and a paved extension continues about 4 miles north into Tallahassee. A separate unpaved track runs alongside for horseback riders.

The Tallahassee Railroad was built in the 1830s to carry cotton from inland plantations to ships at St. Marks, which then took the crop to textile mills across the Atlantic. Its railbed later became this 16-mile state trail, which ends near the confluence of the St. Marks and Wakulla Rivers.

The trail links several towns while keeping alive the memory of Florida's earliest and longest-running railroad for public use. You can see how local communities use this historic connection to explore their surroundings and stay connected.

Parking, water stations, and restrooms are available at Capital Circle, Woodville Sports Complex, and Wakulla Station. The paved surface works for walking, running, or cycling, and an unpaved parallel track is available for people on horseback.

The stretch south of US 98 is part of the Florida National Scenic Trail. The annual Tallahassee Marathon runs the city portion plus the northern six miles of the state section. The Munson Hills off-road bicycle loops, reached by the Paper Cup Trail spur, were expanded to 21 miles.
