Mammoth Cave National Park is a U.S. National Park in central Kentucky, encompassing portions of Mammoth Cave, the longest cave system known in the world. The park was established as a national park on July 1, 1941. It became a World Heritage Site on October 27, 1981, and an international Biosphere Reserve on September 26, 1990. The park's 52,835 acres (21,382 ha) are located primarily in Edmonson County, Kentucky, with small areas extending eastward into Hart County and Barren County. It is centered around the Green River, with a tributary, the Nolin River, feeding into the Green just inside the park. With a confirmed 365 miles of passageways it is by far the world's longest known cave system, being well over twice as long as the second longest cave system, which is South Dakota's Jewel Cave with 145 miles of passageways. Cave animals include five bat species, the Kentucky cave shrimp, cave fish, and cave salamanders. Above ground there are rivers, hiking trails, sinkholes, and springs.

Rated moderate for distance but not a difficult hike. The trail is well maintained and horses are not allowed on most of the trail unlike other areas of the park. You will need to park at the Maple Springs trailhead where there are toilets and picnic benches. The first mile is a connector trail to the Big Hollow trailhead which is mixed use for mountain biking and horseback riding. The Big Hollow portion consists of 2 loops joined in the middle by a connector trail which is great if you decide to make it a shorter hike. We encountered only 6 people on a Spring weekend with great weather.

This trail has been ruined by horses. We experienced ankle deep mud in many places and some treacherous slopes. Numerous trees block the path on the West portion.
It is important to note that only half the trail is recorded on the map. The entire Sal Hollow trail is 8.4 miles end to end which you can add another 2.5 miles with the more easily hiked Buffalo trail to make it a loop.

I hiked this trail 4/22/17 on my way back to IN. Well marked, nice inclines. The view from the scenic outlook was amazing. It was raining when I was there so everything was a vibrant green. Definitely worth the detour off of 65N.

This trail use to be 5 stars then horses were allowed on the trail and ruined it.

Very pretty little walk through the woods. Nice, well kept trail. Very neat scenery with the sink hole, flowing water, rock overhangs, and side trails. All of Mammoth Cave is pet friendly including this trail. Trail is great for dogs. There are two stair cases one of which is perfect for dogs however the other is only suitable for large dogs due to the gaps in steps. We carried out little dog up those couple of steps. Worth your time if you are near by!

Lots of wildlife.

Beautiful spring time trail.
Lots of stairs.
Trails are wide enough to walk side by side. I could easily spend a lot of time in the sink. Very peaceful location.
