Highlands Hammock — Walking a Catwalk Over a Blackwater Cypress Swamp in One of Florida's Oldest State Parks

You turn off the highway just west of Sebring, pay a few dollars at a small ranger station, and within a couple hundred yards the modern world is gone. The light drops. Live oaks lean across the road, draped in resurrection fern and Spanish moss, and the air goes cool and green. Then you park, step onto a narrow wooden catwalk, and walk straight out over black water.

This is Highlands Hammock State Park, and it protects something genuinely rare: one of the largest stands of virgin old-growth hammock left in Florida — forest that was never logged. Some of the live oaks here are estimated at around 1,000 years old. They were already ancient when the first Spanish ships reached this coast.

Here’s the part most people don’t know: this is one of the oldest parks in the entire state. It opened in 1931, and when Florida formally organized its park system in 1935, Highlands Hammock was one of the original four. The Civilian Conservation Corps built much of what you walk on, and there’s a CCC museum on site that tells that story.

The alligators on the swamp trail have seen a million people walk past on that boardwalk. They are not impressed by you. Keep it that way.

What it is

A “hammock,” in Florida, is a hardwood forest growing on slightly higher, drier ground — an island of big trees in a landscape of pine flatwoods and wetland. Highlands Hammock is one of the best surviving examples, and the reason it’s special is simple: it was never cut. Most of Florida’s original forest was logged decades ago. This wasn’t.

So you get a true old-growth canopy — towering live oaks, cabbage palms, hickories, and a tangle of understory that’s been doing its own thing for centuries. Wrapped around and through it is a blackwater cypress swamp, the water stained dark like tea from tannins leaching out of leaves and bark. Bald cypress rise straight out of it, ringed by their strange woody knees poking up through the surface.

The park covers thousands of acres and sits in Highlands County, central Florida, in the gentle ridge country south of Orlando. It’s far enough off the tourist corridor that most visitors are locals, birders, and people who already know what they came for.

What you do there

The whole place is built for an easy, unhurried half-day. There’s no big climb, no technical anything — the appeal is the forest itself.

1. Walk the Cypress Swamp Trail. This is the signature. A wooden catwalk/boardwalk carries you out over the blackwater swamp, past cypress knees, ferns, and dark reflective water. Alligators are a near-constant presence, often lying still right below the railing. Go slow, look down, look up.
2. Hike the short interpretive trails. There are about nine of them, most flat and well under a mile, each showing off a different slice of the habitat — ancient oaks, fern beds, wetland edges. You can do several in a morning.
3. Drive or bike the loop road. A paved loop runs through the park, so you can sample the hammock without much walking, then stop and dip onto a trail wherever it catches you.
4. Take the guided tram tour. A ranger-led tram runs on a schedule and gets you into areas and stories you’d otherwise miss — good if you want the natural and CCC history narrated.
5. Visit the CCC museum to see how the park was built in the 1930s, and camp at the on-site campground if you want to stretch it into an overnight.

Expect the standard Florida state-park fee, around $6 per vehicle. Bring water, closed-toe shoes, and — in warm months — serious bug spray.

Conditions, honestly

• Best season: Late fall through spring. The cooler, drier months are when this park shines. Winter mornings under the oaks are genuinely lovely.
• Heat and storms: Summer is hot and humid, and afternoon thunderstorms are routine from roughly June through September. Go early or expect to get rained on.
• Mosquitoes: The swamp is the draw and the catch. In the warm season the mosquitoes in the swamp are relentless — bring repellent and don’t say you weren’t warned. Cooler months knock them way back.
• Alligators: They’re wild and they’re right there. Stay on the boardwalk, keep kids and dogs close, and never feed or approach them. A fed gator is a dangerous gator and eventually a dead one.
• Difficulty: Easy. Trails are short and mostly flat. This is a place for almost any fitness level, including young kids and grandparents.
• Crowds: Modest. Cool weekends bring families and birders, but it rarely feels packed, and weekday mornings can be near-empty.

What it’s not

This is not a wilderness epic. The trails are short, the loop road is paved, and you’re never far from the car. If you’re after a long backcountry trek or solitude measured in miles, this isn’t that — it’s a concentrated, accessible dose of ancient forest, not a multi-day push.

It’s also not a thrill stop. No springs to swim, no overlooks to leap from, no rapids. The whole reward is slow: thousand-year-old trees, dark water, and gators that out-wait everyone. If your group needs adrenaline, point them elsewhere.

If you go

Nearest town is Sebring, in central Florida’s Highlands County, roughly an hour and a half south of Orlando and a similar haul from Tampa. Bring bug spray (especially May through September), water, sun cover, and closed shoes for the boardwalk and trails. Go in the cooler half of the year if you can, start early, and stay on the trails and boardwalks — the old hammock and the swamp are exactly this intact because people have left them alone. Pack out everything you bring in. If you’re making a central-Florida nature run of it, pair it with Myakka River or another nearby preserve.
