The trail intersects the main road in several spots. The sand dunes are spectacular, and you may come across wildlife like deer if you hike early in the morning or at dusk.

From Jacksonville, follow Interstate 95 north for 20 miles to exit 373. Head east on SR 200 / A1A (Buccaneer Trail) for 10 miles, passing through Yulee and crossing the Intracoastal Waterway into Fernandina Beach on Amelia Island. Continue 2 miles as A1A curves north and merges onto South 8th St. Continue north on South 8th St for 3 miles to Atlantic Ave and turn right. Head east on Atlantic Ave for 1.5 miles. The entrance to Fort Clinch State Park will be on your left. After you stop at the ranger station and pay your park entrance fee, continue 3 miles along the main park road to the parking area at the Fort Clinch Visitor Center. Look for a sign for the Main Loop trailhead there.
From the parking lot, a multi-use sign marks the trail traveling counter-clockwise. Start here on the west leg of the loop, which fronts Egans Creek Marsh.
The trail climbs up a steep hill into the forest. The sweet scent of pine fills the air as you walk through a grove of loblolly pine.
Within the first quarter mile, the trail crosses a road that leads to the River Campground and enters a maritime hammock, undulating across the hills.
After 0.8 miles, it climbs through a patch of saw palmetto to reach the parking area for the Willow Pond Trails, which serves as an alternative access point.
Beneath red bay and live oak, the trail climbs up and over ancient dunes.
Drop through a low drainage filled with Hercules club, then climb up and over a hill before crossing a sandy service road at 1.3 miles.
A glimpse of the salt marsh soon glimmers through the trees. By 1.8 miles, a short spur trail leads to the edge of Egans Creek Marsh, offering a view of the Amelia Island Lighhouse.
As you wind along the edge of the salt marsh, you walk behind tall sea myrtle, which show off their fluffy blooms in fall, then back into a forest of slender yaupon holly.
It winds into a maritime hammock, past gnarled and knobby southern magnolias, some immense, their bark covered with patches of green moss.
Cross the main park road at 2.8 miles. The eastern leg of the loop trail runs along a narrow, hilly strip of forest between the main road and steep dunes.
The trail twists and turns past American beautyberry, saw palmettos, and red mulberry. The sand is soft around some of the sharper curves.
Signs visitors of the fragile nature of this habitat and instruct people not to walk on the dunes.
At 3.3 miles, the trail meets up with the road for a short roadwalk, bypassing an area of sensitive dunes that spill onto the road.
While it re-enters the forest for a tenth of a mile on a steep and twisting path, you resume another short roadwalk soon after.
Hercules’-club rises from a bowl filled with saw palmetto. Crouching low under a bower of wax myrtle, walk between beds of woods ferns.
The trail winds back towards the road, emerging at Egan Creek.
Continue over the bridge, and the trail drops down into a forest of yaupon and sugarberry. Briefly follow the sluggish stream.
The calming aroma of cedar fills the air as the trail crosses the road leading to East Beach Access Area and the Atlantic Campground at 4.5 miles.
Tall slash pines rain needles on the footpath. Within a half mile, the trail passes the brick ruins of the Willow Pond Oil House and the foundations of old light beacons.
These are not accessible from the trail, so stop along the park road after your hike for a look at the interpretive site.
Walking between cabbage palms and cedars, follow the trail to where it exits onto the park road just a few feet from the Visitor Center parking lot, completing the 5.7-mile loop.
