Sulphur Island Loop

A short distance from the bustling metropolis of Orlando, the Sulphur Island Loop Trail explores one of Florida’s endangered ecosystems, the scrub.

Sorrento (28.890069, -81.461369)   9.0 miles   Seminole State Forest

Seminole State Forest protects over 25,800 acres of natural land in Central Florida. In combination with the Florida Trail, the blue-blazed Sulphur Island Loop Trail offers a 9-mile loop hike through several distinctly different landscapes.

A tiny, protected spring along the path provides an oasis of cool, clear water near the beginning and end of the loop.

Directions


 
This hike starts at the northern trailhead shown above. From Interstate 4 in Sanford, take exit 101C and head west on SR 46 for 8 miles before turning right onto 46A. Continue straight for 5 miles, then turn right onto SR 44. In 5.1 miles, turn right onto Brantley Branch Rd. The trailhead parking is a tenth of a mile down the road, on the right.

Hike

To start the hike, look for a large kiosk with maps and brochures near the restrooms at the southwest corner of the parking area.

The beginning of the trail crosses a small field with a white-blazed post in the center.

Follow a mowed pathway through the middle of this open space towards a shady forest tunnel on the opposite edge.

A surprising variety of short plants inhabit this small plot of land, including prickly pear cacti, thistles, and showy native sandhill milkweed.

Entering the forest under a thick canopy, follow white blazes down a well-worn route that was a former section of the Florida Trail.

In a half mile, the trail skirts the edge of Dead Horse Sink, a sizable depression often filled with water.

The trail weaves through a thicket of palmettos, turkey oaks, and Spanish moss-covered live oaks before emerging at the shore of a wide prairie lake.

Continue along the water’s edge through this relatively open area dotted with pines and cabbage palms.

When the trail returns to the woods, the habitat is noticeably different, taking on scrub characteristics.

Fetterbush lyonia and scrub pine border a sandy pathway that widens before passing a bench overlooking Boggy Creek Lake.

In 0.2 mile, the white blazes mark a left turn onto a forest road. Follow the crushed shell avenue east for a quarter mile to an intersection with the Florida Trail.

Turn right, following orange blazes as the road dips through a thick swamp enveloped in cabbage palms and sweetgum trees.

Narrow sand road winding through floodplain Forest road through the swamp


Follow this road for 0.3 mile before taking a sharp turn to the left into a dense subtropical jungle.

A distinct pathway cuts through seas of ferns and palmettos along a slope lined with stands of tall loblolly pines.

Narrow pathway Jungle pathway


Orange blazes guide the way through a maze of green foliage for the next 0.4 miles to Sulphur Camp.

Shortly before reaching the campsite, a side trail leads down a slope to Shark Tooth Spring. Stopping at this little oasis is more convenient on the trip back however, especially on a warm day.

Camping area Sulphur Camp


As the trail passes the campsite, it opens to another forest road. Look to the right for blue blazes on the opposite side of the road marking the Sulphur Island Loop trail.

Shade disappears completely as the habitat quickly transitions to oak scrub.

Blue blazes start loop Blue blazes


Short, shrubby oak trees blanket this preferred home to the state’s only endemic bird, the Florida scrub-jays .

Seminole State Forest is actively managed to preserve this ecosystem as Florida scrub-jays are a threatened species. Blue-blazed posts indicate the trail as it crosses a desert-like landscape.

Narrow path through oak scrub Oak scrub pathway


After crossing a forest road, the trail delves under a thin canopy over dry soils. Sand pines grow in number, interspersed with large gnarled rusty lyonia trees.

On warmer days, snakes such as black racers may bask in patches of sunlight.

With an abundance of flowering trees and shrubs, bees and butterflies dart back and forth across the trail.

For the next mile, the path is generally wide with limited shade, carpeted with pine needles and clusters of lichen.

Footpath with lichens Lichen-lined pathway


At the southwest corner of the loop, a yellow-blazed spur trail leads westward. Turn left to head east through scrubby flatwoods and small patches of young oak hammocks.

This pattern continues for a mile, passing a pine-ringed depression marsh before reaching one of the main forest roads.

Side trail blazed yellow Yellow Spur Trail


Finding the next blaze here is tricky, as the blue trail finishes here and rejoins the Florida Trail to complete the loop.

Head directly across the intersection of roads and look to the left for an orange blaze. The trail then traverses a constructed berm in an area of mixed pine flatwoods and floodplain forest.

Blazes marking Florida Trail Orange blazes


Heading northward along Sulphur Run, the trail becomes progressively wetter, resembling a hydric hammock.

A few small wooden walkways bridge muddier sections through a primeval forest shrouded in large palm fronds.

Walkway through dense palms Palm forest


Shortly after passing through Sulphur Camp again, turn right onto a side trail to take a quick detour to Shark Tooth Spring.

The trail descends through a thick stand of bamboo, emerging at a small crystalline spring run. A bridge over the creek provides access to fill a water bottle if using a filter.

Spring fed waterway Shark Tooth Spring


Back at the orange-blazed Florida Trail, turn right to parallel Sulphur Run on sloping terrain to the forest road, then make another right.

In 0.3 mile, turn left and follow the white blazes for two miles back to the parking area.
