Donnelley Wildlife Management Area Salt Marsh Circuit
Historic rice plantation marsh roads
The Donnelley WMA preserves 8,000 acres of former rice plantation turned waterfowl habitat, where earthen dikes built by enslaved labor in the 1700s still control tidal flow through salt marshes and freshwater impoundments. The main circuit follows maintenance roads across Bear Island Creek to reach observation blinds and old rice mill foundations, passing through spartina grass that stretches unbroken to the horizon. High tide can flood low-lying sections, while low tide exposes oyster beds and creates challenging mud conditions on the access roads.
Easy to moderate depending on tidal conditions and recent rainfall – stock vehicles handle dry conditions, but high-clearance helps during wet periods. Best visited during fall and winter waterfowl seasons when wildlife activity peaks and summer heat subsides. Bring insect repellent year-round and check tide tables before heading out. The Colleton River boundary offers excellent primitive camping spots with sunrise views across the marsh, though you’ll need to pack everything in. Cell service is spotty but emergency coverage exists near the main road.

Frequently asked questions
Can a stock RAV4 or CRV handle this trail?
Yes. This is a flat, dirt dike road with no technical obstacles and only 50 feet of elevation gain across 14 miles. Any stock SUV or even a capable car with decent ground clearance can run it without issue.
When is the best time to visit and are there seasonal closures?
October through March is the sweet spot — cooler temps, lower humidity, and peak waterfowl activity on the impoundments. Summer is brutally hot and buggy in the Lowcountry marsh. Check the SC DNR site before going during hunting season, as access can be restricted on designated hunt days.
Do I need a permit or is there a fee to enter?
No permit and no fee — Donnelley WMA is managed by South Carolina DNR and is free to access. During hunting seasons, non-hunters should wear blaze orange and verify open dates at dnr.sc.gov before arriving.
What's the hardest part of this trail and what should I actually expect?
There's nothing technically hard here. The biggest challenge is soft or muddy dike roads after heavy rain, which can get slick and occasionally rutted. If it's rained hard in the 48 hours prior, a stock vehicle with road tires may want to hang back.
Is dispersed camping available and how far is the nearest gas station?
Dispersed camping is allowed within the WMA — pick a flat spot off the dike road and follow Leave No Trace. The nearest gas is in Walterboro, roughly 20 miles north on US-17A, so fuel up before heading down toward Green Pond.
