St. Marks Trail — Tallahassee to the Gulf by Bike

The Tallahassee–St. Marks Historic Railroad Trail follows the exact bed of Florida’s oldest railroad, a narrow-gauge line completed in 1837 to haul cotton and tobacco from the state capital down to the coast. The tracks are long gone, the right-of-way is now 16.4 miles of smooth asphalt, and the destination at the end is a 19th-century lighthouse standing at the edge of the Gulf of Mexico. Not many rail-trails put you at a tidal river mouth with herons fishing the shallows. This one does.

The trail starts at the southern edge of Tallahassee and runs almost due south, dropping less than 150 feet in elevation across the entire length. That flatness is its defining trait — you could ride it on a beach cruiser with a flat tire and still finish. Families, retirees, serious road cyclists, and people who haven’t been on a bike in a decade all share this pavement without incident. On a clear February morning with the canopy closed over the trail and nobody else around, it’s close to perfect.

What it is

The St. Marks Trail is part of the Florida Greenways and Trails system and sits within Apalachicola National Forest territory as it moves south. The northern trailhead is at Capital Circle Southwest in Tallahassee; the southern terminus is in the village of St. Marks, population roughly 300, where the St. Marks River meets Apalachee Bay.

The numbers: 16.4 miles one way, 32.8 miles round trip. Fully paved, 12 feet wide, open to bicycles, pedestrians, and inline skaters. The trail surface is maintained asphalt — reasonably smooth, occasional crack repairs, no loose gravel. There are restrooms at the northern trailhead, at Wakulla Station roughly halfway, and at the southern terminus. Water is available at the trailhead and at Wakulla Station. Parking is free at both the Capital Circle trailhead and at a smaller lot in St. Marks.

The St. Marks National Wildlife Refuge spans the final miles of the ride and most of what you see on either side of the trail near the coast. The refuge protects 70,000 acres of coastal wetlands, pine flatwoods, and saltmarsh — it is the second-oldest national wildlife refuge in the United States, established in 1931. The St. Marks Lighthouse at the end of the trail was built in 1831, making it older than the state of Florida itself.

What you do there

Rent or bring a bike. If you don’t have one, Tallahassee has rental shops near the university district. A standard hybrid or road bike handles the surface easily. A fat bike or mountain bike is overkill but won’t hurt anything. Road bikes with 25c or wider tires are fine.

The standard ride is out-and-back from the Capital Circle trailhead to St. Marks and back — roughly 2.5 to 3.5 hours at a relaxed pace. Most riders turn around at the Lighthouse parking area or grab food in the village before heading back.

Wakulla Station, at mile 8, is a shaded picnic area and the halfway marker. It’s a sensible turnaround for anyone who wants a shorter day — a 16-mile round trip from here puts you at a manageable effort level for beginners or young kids.

In St. Marks village, Posey’s Tropical Seafood Bar is the traditional endpoint meal — cold beer, fried mullet, a picnic table on the water. It is exactly what you want after 16 miles in Florida humidity. The Riverside Café is a second option. Neither is fancy. Both are correct.

The lighthouse is inside the National Wildlife Refuge. There is a $5 vehicle fee to enter the refuge by car, but cyclists arrive by trail and are not charged. You can walk out to the lighthouse grounds, look at the salt flats, and watch roseate spoonbills forage in the shallows if you arrive in the right season.

If you’re doing a one-way shuttle, park a second car in St. Marks or arrange a pickup. The village is small — don’t expect ride-shares.

Conditions, honestly

• Best months: November through March. The trail is shaded but humidity and heat in summer (June–September) make midday riding genuinely unpleasant. Start before 8 a.m. if you’re going in summer.
• Crowds: Weekends from January through April bring steady traffic. The trail is wide enough that it rarely feels congested, but you will share it. Weekday mornings are quiet.
• Wildlife hazards: The trail cuts through wetland habitat. Alligators are present — they occasionally sun on the trail surface, especially near the southern end. Give them space (10+ feet) and go around. Don’t approach, don’t provoke, don’t feed. This is not a joke.
• Insects: Mosquitoes in summer are severe. DEET is not optional from May through September. Sandflies near the coast in fall are irritating but less brutal.
• Weather: Afternoon thunderstorms from June through September are daily. If you hear thunder, get under a structure. Lightning on an open trail is not a minor concern in Florida.
• Hurricane season closures: The southern section through the refuge can close after major storms. Check Florida State Parks and the refuge website before driving out.

“The trail ends at a lighthouse that’s older than the state of Florida. That’s either the best possible endpoint or a sign that Florida has always rewarded people willing to go the distance by bike.”

What it’s not

This is not a challenging ride. If you’re a cyclist looking for climbing, technical terrain, or anything resembling effort, the St. Marks Trail will bore you by mile four. It is dead flat on converted rail-bed — the gradient barely registers. There are no dirt sections, no obstacles, no elevation to speak of.

It’s also not a wilderness trail. The northern half runs through suburban Tallahassee, and the noise of Capital Circle is present at the start. The southern half quiets down considerably, but this is never a remote or isolated experience.

Don’t plan on wildlife sightings being guaranteed. The refuge is real and the birds are there, but they don’t perform on a schedule.

If you go

Base: Tallahassee — 15 minutes from the northern trailhead. St. Marks has no hotels; it’s a day trip.

Bring: Water for the full distance (Wakulla Station refills but distances between water are long in heat), sunscreen, insect repellent, a light snack, and a phone with the Gaia GPS or AllTrails app loaded with the trail route as backup.

Pair it with: A stop at St. Marks National Wildlife Refuge visitor center, which is near the lighthouse and has good interpretive exhibits on the coastal ecosystem. Or drive 30 minutes west after your ride to Wakulla Springs State Park, one of the world’s largest freshwater springs, for a swim in 68°F water that will reset your core temperature completely.

Fee: Free to ride. $5 vehicle fee if you drive into the wildlife refuge, but trail cyclists enter free.

FAQ

Do I need a permit or registration to ride the St. Marks Trail? No permit needed. The trail is free and open to the public. Cyclists entering the St. Marks National Wildlife Refuge by trail are not charged the vehicle fee.

Can I ride the trail with a young child or trailer bike? Yes — the trail is flat, paved, and wide, making it one of the most family-friendly rail-trails in Florida. Many families ride to Wakulla Station and back as a 16-mile half-day. The full round trip (33 miles) is long for young children; plan a turnaround point based on their stamina.

Is there anywhere to rent bikes near the trailhead? Rental shops operate in Tallahassee near FSU and the Capital Circle area. Call ahead to confirm availability, especially on weekends from January through April when demand is highest.
