Underwhelming, to be honest. The wildlife and natural geography are more beautiful and interesting than the monument.
Very beautiful cave formations and a nice visitor's center.
The cave is nice, but for me it was the abundant wildlife such as bison and prairie dogs that endeared the park to me.
Beautiful scenery and wonderful wildlife. Hiked through here for about a week while hiking the Appalachian Trail. They are serious about their backcountry permits and designated campsites, and you must take precautions with your food and scented items due to bears, but it was worth it! I only wish other hikers had not left so much trash along the trail.
Nice hiking, great visitors center, astonishing landscape.
