Congaree National Park: Old-Growth Forest Hiking Guide

Congaree National Park preserves the largest intact old-growth bottomland hardwood forest in the United States — a cathedral of bald cypress and water tupelo trees that dwarf anything most visitors have seen before. Champion trees tower 150 feet overhead, the night skies rank among the darkest east of the Mississippi, and for two weeks every spring, synchronous fireflies light the forest in coordinated pulses that draw visitors from across the country. Admission is free.

Top Trails

Boardwalk Loop — 2.4 miles, accessible

Start here. An elevated boardwalk winds through the floodplain forest past ancient cypress knees, hanging Spanish moss, and trees up to 1,000 years old. This is the most accessible trail in the park and the best introduction to bottomland forest anywhere in the eastern US. Wheelchair accessible for most of the route. Allow 1.5 hours.

Weston Lake Loop — 4.4 miles

Branches off the boardwalk to loop through deeper forest to Weston Lake, an oxbow lake formed when the Congaree River changed course. The old-growth tupelo and bald cypress around the lake are among the largest in the park. Watch for river otters and barred owls.

Oakridge Trail — 7 miles one way

The longest maintained trail in the park, running the length of the park on a natural levee above the floodplain. In dry conditions, this is the best trail for solitude and wildlife watching. In wet conditions, expect sections underwater. The trail connects to the canoe trail landing.

Cedar Creek Canoe Trail — 15 miles

A blackwater paddle through the heart of the floodplain forest, following Cedar Creek to the Congaree River. The route is marked with orange blazes on trees. Canoes must be carried on a few short portages. An overnight permit (free) is required for camping on the route; day paddles need no permit. Canoe rentals are available in Columbia.

Synchronous Fireflies

Congaree is one of only two places in the United States (the other is Elkmont in Great Smoky Mountains) where synchronous fireflies flash in coordinated patterns. The event occurs for approximately two weeks in mid-May to early June, when males flash in unison to attract females.

Timed-entry tickets are required for the firefly viewing events and sell out months in advance. Check nps.gov/cong starting in March for ticket release dates. Tickets are free but limited — this is one of the most competitive NPS tickets in the country. Bring red-lens flashlights only (white light disrupts the display).

Wildlife

• River otters: Active year-round in the creek channels — one of the most reliable otter sightings in the Southeast
• Barred owls: Call constantly at dawn and dusk; their "who cooks for you" call echoes through the cypress
• Wild turkeys: Walk the forest floor in groups; often seen along the boardwalk
• Cottonmouth snakes: Present near water, especially in summer. Watch where you step and never put hands under logs or into brush near the water's edge. They are not aggressive if you give them space.
• Deer, foxes, and 200+ bird species including prothonotary warbler (the park's signature songbird)

Night Sky

Congaree holds a Gold Tier International Dark Sky Park designation — among the darkest night skies east of the Mississippi. The park offers periodic night sky programs; check the NPS website for the schedule. The boardwalk is accessible at night with a flashlight (use red light to preserve night vision).

Flooding

The floodplain floods an average of 10 times per year. Flooding is part of the ecosystem and what keeps the forest in old-growth condition — but it means your visit can be underwater. Always check current conditions at nps.gov/cong before driving down. The park website shows which trails are currently passable. Flooding is most common December through April.

Best Time to Go

• November to February: Best for hiking — cool temperatures, low humidity, no bugs, migratory birds present, and flood risk lower.
• March to April: Wildflowers and spring migrants arrive. Flooding still possible but trees are leafing out.
• Mid-May to early June: Firefly season — plan far ahead for tickets.
• July to September: Technically open but brutal — 95°F heat, near-100% humidity, and mosquitoes thick enough to drive unprepared visitors back to their cars within minutes.

Getting There

The main entrance is at 100 National Park Road, Hopkins SC — 20 miles southeast of downtown Columbia. From Charlotte NC: 90 minutes south on I-77. The park is day-use only (no overnight lodging in the park). Columbia has a full range of hotels and is a pleasant base with good food and the University of South Carolina campus.
