12 Mile Creek Run in Sullivan’s Island offers an invigorating coastal hiking experience that balances natural charm with practical adventure. Stretching roughly 5.3 miles round trip with a modest elevation gain of about 150 feet, this trail moves through salt marsh edges, forested buffers, and tidal creek crossings. The terrain is a mix of well-maintained dirt paths, some sandy patches, and occasional wooden boardwalks where the creek dares you to follow its winding course. The trail demands respect rather than domination, as the slightly uneven footing and occasional muddy spots require steady footwear and alert footing.

Starting near the eastern shores of Sullivan’s Island, the creek itself leads the route with a persistent current that pushes exploration forward. The air carries the sharp tang of salt and pine, while seasonal breezes lend cool relief on warmer days. Birdsong punctuates the quiet moments between waves lapping nearby, and the creek occasionally seems to whisper stories of its long-standing place in this coastal ecosystem.

For those planning the run, hydration is critical—several points lack immediate fresh water sources, so carry enough and refill where possible before arrival. Footwear with solid grip and protection against mud and sand will ease the journey considerably; waterproof trail shoes or boots are a good choice. The best hiking window falls between October and May when humidity fades and mosquitoes retreat, though mild winters mean the trail rarely freezes or snows.

Keep in mind this is not a race but an engagement with a landscape fiercely itself, with wildlife rhythms and natural challenges. Timing your hike around tides can enhance the experience—lower tides expose hidden mudflats and make some sections easier, while high tides amplify the creek’s presence and beauty.

The trail leads to several spots offering sweeping views of the marsh’s shifting patterns and, on clearer days, of the Charleston skyline in the distance. Notably, a quieter side path descends to a lesser-known beach overlook that rewards steady travelers with a pause for reflection or photography. Throughout the trek, the marsh reacts to your presence, with crabs skittering away and herons standing sentinel in the shallows.

Whether you’re here for a brisk workout or a slow immersion, 12 Mile Creek Run presents a coastal adventure that’s as much about practical preparation as appreciation. It invites you to listen, move carefully, and leave no trace, recognizing the delicate balance that sustains this vibrant coastal corridor.
