The Chimney Top and Half Moon Arch Trail offers a fascinating journey through the Red River Gorge, blending accessible overlooks with more adventurous, unmarked paths. You'll begin with the Chimney Top Rock Trail, a short, mostly paved walk to a stunning viewpoint 400 feet above the Red River, offering expansive views of Half Moon Rock and the surrounding gorge. The route then transitions to the Half Moon Arch Trail, an unofficial path that requires navigating steep terrain and scrambling over exposed cliffs to reach the arch itself, which provides unique framed views of the valley.
This 2.1-mile (3.4 km) hiking trail is rated easy overall, with a total elevation gain of 398 feet (121 metres), and typically takes about 1 hour and 2 minutes to complete. While the Chimney Top section is family-friendly, the Half Moon Arch portion is best for experienced hikers comfortable with unmarked routes and some exposure. Always exercise caution, especially at the Chimney Top overlook's steep drop-offs, and avoid venturing alone on the Half Moon Arch section due to its inherent risks.
Historically, Half Moon Arch was a significant site for early rock climbing, and it remains one of the most accessible "secret" arches in the Red River Gorge, visible from the Chimney Top Overlook. The area is known for its densely forested valleys, and in late May, mountain laurels bloom, adding a sweet scent to the air. This combination of well-maintained paths and rugged, unofficial trails makes for a diverse and memorable Red River Gorge experience.

The combined route, as outlined, is approximately 3.4 km (2.1 miles) long and generally takes about 1 hour and 2 minutes to complete. This duration accounts for the relatively short distances of both trails, though the Half Moon Arch section can be slower due to its rugged, unmarked nature.
The Chimney Top Rock Trail (#235) is short, easy, and largely flat, making it suitable for beginners and families. However, the Half Moon Arch Trail is unmarked, rugged, and involves scrambling over exposed cliffs and ledges. It requires good sure-footedness and is not recommended for young children or those uncomfortable with heights and challenging terrain. Extreme caution is advised on both trails near cliff edges.
Parking is available at the trailhead, which is accessed via National Forest Road 10 (Chimney Top Road). This is a 4.5-mile gravel road. Be aware that the road may be closed due to conditions, in which case you would need to walk the road to reach the trailhead.
Generally, there are no specific permits or entrance fees required to hike the Chimney Top and Half Moon Arch Trail within the Daniel Boone National Forest. However, always check the official Daniel Boone National Forest website for any updated regulations or fee changes, especially for specific activities or camping.
While dogs are generally permitted on trails within Daniel Boone National Forest, the Half Moon Arch Trail's rugged terrain, including scrambling over exposed cliffs and ledges, might be challenging or unsafe for some dogs. Always keep your dog on a leash and ensure they are capable of handling the varied conditions.
Spring and fall offer pleasant temperatures and beautiful scenery. Late May is particularly special as mountain laurels are in full bloom, perfuming the air. Winter conditions can make the trails, especially Half Moon Arch, more hazardous due to ice or snow on exposed ledges.
The Chimney Top Rock Trail culminates in breathtaking panoramic views of the Red River Gorge, including the river below, surrounding mountains, and sheer cliffs. From this overlook, you can also spot Half Moon Arch. The Half Moon Arch Trail leads to the iconic Half Moon Arch itself, a rounded sandstone pinnacle, and offers impressive views of the gorge, including glimpses of Chimney Top Rock.
Both trails have significant safety concerns. The Chimney Top Overlook has unrailed cut-throughs to exposed cliff edges, and fatalities have occurred from falls. The Half Moon Arch Trail is unmarked and involves scrambling over exposed cliffs and rock ledges; it is strongly advised not to hike it alone. Always exercise extreme caution near cliff edges, wear appropriate footwear, and be aware of your surroundings.
Yes, the route primarily follows sections of the Chimney Top Trail #235 and the Half Moon Arch Trail. It also briefly touches upon the Princess Arch Trail #233.
The Chimney Top Rock Trail (#235) is short, flat, and partially paved, traversing a pine-hardwood forest. In contrast, the Half Moon Arch Trail is an unmarked, rugged path that starts as a deer path, descends a washed-out hillside, and requires scrambling over exposed cliffs and rock ledges to reach the arch. Hikers need to be prepared for varied and challenging terrain on the Half Moon Arch section.
During late May, you can enjoy the fragrant mountain laurels in full bloom. Keep an eye out for large birds of prey, such as Red Shouldered Hawks and the endangered Peregrine Falcons, soaring above the canyon. As with any natural area, you may also encounter various other forest animals and plant life typical of the Red River Gorge Geological Area.
