Overview
The Indian Mounds Wilderness Trail provides the primary access into the approximately 12,000-acre Indian Mounds Wilderness in the northern section of Sabine National Forest, covering bottomland and upland hardwood terrain that includes some of the most undeveloped forest in East Texas. The wilderness takes its name from pre-contact archaeological sites within its boundaries, and the trail passes through the mixed hardwood environment that supported Indigenous occupation of this part of the Pineywoods for thousands of years. The 6-mile out-and-back is the main maintained route; the wilderness interior requires navigation skills beyond the trail.
No permit required. No fee. Dogs welcome on leash. Cell service is absent throughout.
The Route
Miles 0 to 2: Trailhead to wilderness boundary. From the Indian Mounds Campground trailhead on Forest Road 507, the trail heads east into transitional pine-hardwood upland. The wilderness boundary is approximately 1 mile in; the change in character is subtle but real, with old-growth-influenced trees appearing as the managed forest gives way to the protected wilderness. Creek drainages cross the route in the first section.
Miles 2 to 3: Bottomland core. The trail descends into the bottomland hardwood zone, where water oak, overcup oak, sweetgum, and American hornbeam replace the pine. This is the most ecologically distinctive section of the trail, with old bottomland trees and a rich understory. Archaeological sites are documented in this area; observe without touching or removing anything. Turnaround at the far end of the maintained trail at mile 3.
When to Hike
November through March: Best conditions. Low insect pressure and cooler temperatures. The leafless winter canopy improves visibility through the bottomland forest.
April: Spring wildflowers in the bottomland. Warblers arriving for breeding season.
May through September: High heat and humidity combined with significant insect pressure. Not recommended for most hikers.
October: Good fall hiking as temperatures moderate.
What to Bring
Many hikers carry 2 liters of water for this round trip. Creek water is available but must be filtered. Insect repellent is important year-round in East Texas bottomland. Detailed offline maps (cell service is absent). Blaze orange during hunting seasons (October through January).
Trailhead Access
Indian Mounds Campground is on Forest Road 507, north of San Augustine via TX-21 east and connecting forest roads. The campground has a vault restroom and basic facilities.
Nearby
The Sabine River Trail covers different bottomland terrain along the Sabine River corridor. The Four Notch Trail provides a longer interior route in a different section of the forest. Review the Leave No Trace seven principles and our checking conditions guide before entering the wilderness.
