The Komoot route for the Skylight Cave Lewis Hollow Trail is approximately 10.15 km (6.3 miles) long. It generally takes around 3 hours to complete, depending on your pace and how much time you spend exploring the cave.
The trail involves a steep climb up Cumberland Mountain, often following a boulder-strewn drainage. You'll encounter rock walls as you ascend. The environment is very green and cool, especially after rain, with a creek running alongside the trail that eventually disappears underground past the Skylight Cave. The hike transitions from drier, more open forests at the base to lusher woods closer to the summit.
The Skylight Cave is the primary draw of this trail. It's named for a secondary opening above its entrance, which allows natural sunlight to filter into a large room inside the cave. This creates a distinctive visual experience and makes it a popular destination, offering a natural alternative to the larger, reservation-required Gap Cave.
This trail is generally rated as moderate to strenuous. The one-mile section leading directly to the Skylight Cave involves a significant uphill climb. While rewarding, it might be challenging for absolute beginners. Those looking for a less strenuous option might consider other trails in Cumberland Gap National Historical Park.
Late spring and summer are particularly beautiful times to hike the trail, as the Lewis Hollow Trail is known for its vibrant pink lady slippers. The environment is also described as very green and cool, especially after rainfall, which can enhance the experience. Be prepared for potentially slippery conditions after rain.
Yes, dogs are permitted on this trail within Cumberland Gap National Historical Park. However, they must be kept on a leash no longer than 6 feet (1.8 meters) at all times. Please remember to pack out any waste.
There is no entrance fee to Cumberland Gap National Historical Park. However, specific activities or areas might require permits. For the most current information on permits or regulations, it's always best to check the official National Park Service website for Cumberland Gap National Historical Park before your visit.
Parking is available at the trailhead within Cumberland Gap National Historical Park. It's advisable to arrive early, especially on weekends or during peak seasons, as this is one of the most hiked trails in the park.
Yes, the Komoot route for the Skylight Cave Lewis Hollow Trail intersects with several other paths. It includes sections of the Great Eastern Trail - Pine Mountain Link, the Boone Trail, and the Ridge Trail. A small portion also overlaps with the Cumberland Gap Loop and the Wilderness Road Trail.
If you plan to continue beyond the Skylight Cave, be aware that the trail becomes much steeper and can be very slippery. The longer Lewis Hollow-Gap Loop, which encompasses this trail, is considered strenuous due to long and difficult ascents and descents of Cumberland Mountain with occasional rough footing.
The Lewis Hollow Trail is particularly known for its beautiful pink lady slippers, which can be seen in late spring and summer. The lush, green environment also supports diverse flora, and you might encounter various forest wildlife typical of the Appalachian region.
