Congaree National Park
Originally established as a National Monument in 1976 and elevated to National Park status in 2003, South Carolina’s Congaree remains one of the National Park Service’s hidden gems. Spanning a modest 26,692 acres, it is one of the smaller parks in the system, yet it protects the largest intact expanse of old-growth bottomland hardwood forest remaining in the southeastern United States. Because this land escaped the reach of the logging industry, its massive trees have been allowed to thrive for centuries within a nutrient-rich floodplain. Today, this highly biodiverse ecosystem serves as a sanctuary, boasting some of the tallest deciduous canopies in the world.
About Our Hike
To avoid the infamous mud and sloppy trail conditions, we opted to stay on the elevated boardwalk for our entire trek. While the park is notorious for its oppressive summer heat, relentless mosquitoes, and trail-spanning spider webs, visiting in the dead of winter proved to be a stroke of genius. It was the perfect way to experience the park’s stark winter beauty without the bugs or the swamp’s signature foul odors. We were a bit bummed to miss the magical synchronous fireflies that light up the Firefly Trail in late spring, but the peaceful, insect-free atmosphere was a fair trade-off.

Pictures Tell the Story
After checking the mosquito meter and getting the official “all clear,” we were incredibly thankful for the winter chill. The near-freezing weather meant we completely bypassed the park’s legendary insect war zone.
Our original plan was to hike the full loop, but with the west side of the boardwalk closed for construction, we pivoted to the east side. We made up for it by exploring several of the spur trails, which gave us an even closer look at the winter landscape from the safety of the boardwalk.
The first section of the boardwalk sits high above the swampy floor, guarded by sturdy wooden railings. It’s hard to imagine, but I’ve seen photos where the floodwaters rise high enough to lick the bottom of the floor planks—or even submerge them entirely. Thankfully, the water stayed well below our feet, giving us a dry, bird’s-eye view of the floodplain.
As we ventured farther, the scenery shifted. One of the newer spur trails was built much lower to the ground, trading in the high, fenced-in railings for an open-air experience. It felt like we were truly part of the forest floor, though it definitely made me extra grateful for the dry winter weather!
While the views from the boardwalk shifted with every turn, the swampy landscape remained a constant. It’s a vivid reminder that the vast majority of the park’s acreage lies within the Congaree and Wateree River floodplains. This ‘common denominator’ of water and mud is exactly what makes the park so uniquely biodiverse—and exactly why we were so glad to have the boardwalk beneath our boots.
Everywhere we looked, the iconic ‘knees’ of the bald cypress trees poked through the swamp floor like wooden stalagmites. These unique root extensions are the signature of the Congaree floodplain, adding a prehistoric feel to the entire hike.
One of the highlights of our trek was a spur trail that led us directly out to the edge of Weston Lake. This oxbow lake—once a bend in the Congaree River—now sits as a peaceful, mirror-like body of water framed by ancient trees.
It’s clear the park is investing in the visitor experience. In addition to ongoing repairs to weathered boards, a brand-new boardwalk spur has just been completed, and another is currently under construction. These additions lengthen the distance visitors can venture farther into the forest without ever having to step foot on the muddy swamp floor.
While exploring, we stopped to chat with a pair of dedicated volunteers who were busy adding steps to a section of the boardwalk. This new staircase will make it much easier for visitors to transition down to the dirt trails below. They shared that they’ve been volunteering at Congaree for over three years—a true testament to the passion people have for preserving this unique landscape.
Eventually, our path met the west side of the boardwalk, which was closed for the ongoing construction. Reaching the barricade served as our official turnaround point. Even though the loop was cut short, the detour was a small price to pay for all the trail improvements currently underway.
As someone who always looks for the local flora, I was captivated by the park’s understory. The dwarf palmettos and vibrant evergreen ferns provided a lush, green contrast to the gray trunks of the winter forest. These hardy plants thrive in the damp, shaded environment of the floodplain, making the ground feel just as alive as the towering canopy above.
I was fascinated to learn about Eurhynchium moss during our walk. It thrives in the high-moisture environment of the Congaree basin, creating lush light green textures on fallen logs. It’s amazing how much life you can find even in the middle of winter.
Congaree is known for its champion trees, and this 150-foot Loblolly Pine is a former state champ. While the title of tallest is always being challenged by newer growth, this massive pine remains a cornerstone of the park’s old-growth heritage. It’s a vertical reminder of why this land was worth protecting.
Wildlife was sparse during our walk; we spotted very few birds and none of the elusive fox squirrels that call Congaree home. Aside from the massive bald cypress trees, there wasn’t much for my husband to capture with his camera, as the forest seemed to be in a deep winter slumber.
Because we’d kept such a relaxing pace, the winter chill finally started to catch up with me. I realized I hadn’t been pushing myself enough to stay warm, so I picked up the pace as we approached the visitor center, eager for the indoor warmth and a chance to defrost.

Final Thoughts on Our Hike
Despite the quiet wildlife and the detours for construction, our winter trek through Congaree was a refreshing success. Trading the “war zone” of summer mosquitoes for near-freezing temperatures allowed us to truly appreciate the intricate details of the floodplain—from the prehistoric-looking dwarf palmettos and feathery Eurhynchium moss to the towering 150-foot Loblolly champion. The boardwalk kept us high and dry above the legendary swamp mud, offering a front-row seat to an ecosystem that feels ancient and untouched. By the time the visitor center came back into view, I was definitely ready to swap the chilly air for some indoor warmth, but the peaceful stillness of the winter swamp was well worth the shivers.
Questions
- • When it comes to exploring the outdoors, are you like me and willing to trade the freezing cold for a bug-free experience, or do you prefer the warmth even if it means dealing with the ‘mosquito war zone’? ~ I very much prefer the warmth, but based on what I’d read about Congaree, I knew it would be an exception and that we should visit it in the winter.
- • For the photographers out there: do you enjoy the challenge of finding beauty in the quiet winter landscape, or do you prefer waiting for the lush colors and wildlife of spring and summer? ~ I prefer seeing wildlife.
- • Congaree is known for its incredible champion trees and unique floodplains. What’s the most unique or unexpected National Park you’ve ever visited? ~ I found the ancient dwellings in Mesa Verde to be very different from what I’d expected.
I’m linking up with Jenn from Runs with Pugs and Jenny of Runners Fly for Tuesday topics Link-Up. Be sure to check out not only the hosts’ posts, but those of the other great bloggers joining in on the fun!
Pat and I are hoping to visit in April, before the heat and humidity (and mosquitoes!) become unbearable! Out of curiosity, where did you stay?
We stopped and spent a few hours at Congaree on our way from Charlotte, NC to Beaufort, SC so we didn’t stay locally. I hope the fireflies are out when you’re there!
Your winter visit to Congaree National Park sounds like perfect timing!! Cold, dry, mosquito-free is basically the jackpot for a swamp hike. Those boardwalk sections and cypress knees give it such a prehistoric vibe, and I love how peaceful and quiet everything looks.
I love these relaxed walks where you have enough time to focus on the small things.
It really was a great time to visit the park; although, it would have be fun to see the synchronous fireflies in late spring. I’m pretty sure avoiding the mosquitos was the better way to go for me, though!
Aren’t those cypress knees cool?
I think I prefer the warmth…Cold brings snow and ice and slippery trails.
Your photos make me miss hiking… during the Pandemic I used to hike several times a week.
BTW: saw cypress knees at the other Delray bird sanctuary.
The day we visited was an exceptionally cold day for the area so when I planned the trip, I didn’t expect to get so cold. That said, it still beat getting eaten by mosquitos! Cypress knees are pretty cool and so very different from what we see in our forests, right?
Well let’s see. Mosquitos LOVE me, so I would much rather go in the cold than get 1000 mosquito bites. And, I like how you describe the forest as being in a “deep winter slumber.” It looks very peaceful! I would prefer to see wildlife, but this sounds really nice too.
Yep, mosquitos love me, too, but completely ignore my husband.
