Wind Cave Canyon Trail is a 3.6 mile out and back trail located near Custer, South Dakota and is good for all skill levels. The trail is primarily used for hiking and is accessible from April until October.
Nice little trail not too far from Mount Rushmore. Beautiful area!
I did Wind Cave Canyon Trail over to Highland Creek trail and around on Centennial for a decent loop. There were a lot of elk and bison, plenty of prairie (and a ton of fat prairie dogs), followed by some nice hiking in the woods.
