Red Trillium Trail

3.3 Mile Loop

Difficulty – Strenuous
This trail ascends 400 ft in elevation along a natural surface trail, with many rapid ascents and descents, uneven surfaces. It travels near very steep bluffs. The trail is meticulously cut into the hillside to create a narrow level path that employs many switchbacks to ease the ascent for hikers. Hikers need to be in good physical condition. Please walk single file to protect the trailside botanicals.

Are Dogs Allowed on the Red Trillium Trail?
Although most Arc trails do not permit dogs due to the density of flower bulbs lining the trails, YES, Red Trillium Trail does permit dogs if kept on a 6-foot leash. To protect flower bulbs and native plants from soil compaction and accidental contact damage, please guide your dog to walk either in front of you or behind you.

The Red Trillium Trail is a challenging but rewarding back country trail with stunning views of the Ohio River below and the hills of Kentucky on its far shore. Rock Run is an incredibly picturesque landscape. After reaching the ridgetop from the base of the hill on HWY-52, the trail drops down into the rich woodlands of Trillium Hollow, where the sounds of the highway and the bustling enterprises of the Ohio River suddenly vanish. Here one is immersed in the deep woods – surrounded by birds songs, ferns, frogs, and native wildflowers.  The historical remnants of the sandstone mining can be seen at many points along the trail, including massive 19th century boundary markers carved out of stone, as well as the large vernal pools that are now breeding habitat for a variety of amphibians. The trail then loops back to the ridge line, and back to the trailhead. The road entrance is.fully signed to a graveled parking lot and the path is clearly marked with directional arrows. To see the Red Trilliums, visit in mid-April. These flower bulbs take 7 years to bloom. Please do not pick or disturb any of Rock Run’s flowers. Picking spring wildflowers will either kill them outright, or set them back for many years.

Driving from a long distance?
Their are several lodging options in the Portsmouth region as well as in nearby Shawnee State Park, which offers lodge rooms, cabins, and campground; but it would be remiss not to point out that Rock Run’s trail entrance is directly across and easy walking distance from a private campground and simple cabin rental known as Sandy Springs.
