Best hikes and photo spots at Mammoth Cave, Big South Fork and Cumberland Gap
Overlooks, waterfalls, arches and a three-state summit in Kentucky's three big national park sites, with the trail lengths and closures NPS has posted.
Kentucky's three big national park sites each have a handful of short walks that end at a real view. This guide sticks to what the National Park Service publishes: trail lengths, difficulty and times appear only where the park states them, and every closure below comes from a current NPS alert or park page. Checked Oct. 24, 2026. Check each park's conditions page before you go.
Mammoth Cave
Most people come for the cave, but the park's surface trails have some good river-valley views.
Sunset Point is closed right now. The park's favorite Green River Valley panorama is at the end of a short ridge-top walk near the visitor center, and its things-to-do page calls it the spot for spring foliage and fall color. But the park says the Old Guides Trail, Heritage Trail, Sunset Point Trail and parts of the Sinkhole Trail are closed for a trail rehabilitation project. Skip it until the park lifts the closure.
Good choices that are open, per the park's current alerts:
- Green River Bluffs Overlook. A 1.3-mile (2.1 km) trail from the picnic area leads to one of the best views of the Green River winding through the park.
- Cedar Sink Trail. A 1-mile loop, about 45 to 60 minutes, down into a huge sinkhole with rock faces and cave springs. Expect 295 stairs. The park calls it a favorite for spring and summer wildflowers and suggests going early for a quiet hike.
- Turnhole Bend Overlook. A half-mile loop on the south side, off Brownsville Road, passes deep sinkholes on the way to benches overlooking the Green River.
- Doyel Valley Overlook. The only scenic overlook in the park you can drive to, on Mammoth Cave Parkway 2.2 miles south of the visitor center.
After dark. The park says "half the park is after dark." For stargazing it suggests a red light, a wide-open spot like the fields and parking lots near the visitor center, and distance from headlights and building lights. Rangers also run night sky programs, so check the program schedule.
One more alert to know: the Green River Ferry is out of service for low water, so plan routes to the north side around it.
Big South Fork
The park lists 350 miles of trails, and that overlooks all along the river gorge catch the sun's first or last light of the day. Drones are prohibited, per a current park alert.
On the Kentucky side:
- Yahoo Falls Loop. A 1-mile loop to 113-foot Yahoo Falls. It's easy except for some very steep metal steps, and it passes behind the falls under a large rock shelter. The flow drops a lot in dry weather.
- Bear Creek Overlook. An easy quarter-mile walk to what the park calls one of the longest views along the river gorge.
- Split Bow Arch. You can see the arch from an overlook about 100 feet from a small parking area, or take the easy 1.28-mile round trip to its base from the Bear Creek Overlook trailhead.
- Blue Heron Loop. A moderate 6.5-mile loop past the Blue Heron mining camp, up to the gorge rim and two overlooks, and through a cliff opening called "Cracks in the rocks." Note that the historic Blue Heron Tipple Bridge has been temporarily closed since late September 2025 for safety.
Across the line in Tennessee:
- Twin Arches. Seven-tenths of a mile one way, easy to moderate with some very steep steps. Allow an hour round trip. A 4.5-mile loop continues on if you want more.
- East Rim Overlook. An easy 300-foot paved walk at the end of East Rim Road.
- Sunset Overlook. An easy 1.3-mile walk each way from the East Rim Trailhead, about an hour total. There are no railings or fences, so use extreme caution, especially with children and pets.
Cumberland Gap
The park's hiking page lists lengths, difficulty and times for each trail.
- Pinnacle Overlook. 600 feet one way, easy, about 5 minutes. It's the park's most visited overlook, and on a clear day you can see three states and about 100 miles. You park in Kentucky and walk into Virginia. A paved, accessible section runs 200 yards from the right end of the parking area.
- Tri-State Peak Trail. Moderate, 0.6 miles one way, but you have to hike other trails first, which makes it at least 1.2 miles one way. At the top you can stand in Tennessee, Kentucky and Virginia at once, with a view toward Middlesboro.
- Wilderness Road Trail. 2.4 miles one way, easy to moderate with some strenuous parts, about 1.5 hours one way through the historic gap.
- Ewing Trail. Strenuous, 2.5 miles one way, about 2 hours, with lots of switchbacks. The park calls it "stunning view after stunning view" up to the Ridge Trail, near White Rocks and Sand Cave. It's wet and slippery in rainy season.
- Lewis Hollow Trail. Strenuous, 1.7 miles one way, about an hour. Skylight Cave is closed September through May, but you can see it from the trail all year.
Cumberland Gap had no active NPS alerts when we checked.
