Great trail. The loop takes you almost to the top of the mountain and has great views on the east side. Total distance I traveled with a couple of extra treks was 6.7 miles. I think the loop by its self is 5.1 miles. Walking up to the falls is ok but only takes a couple of min to get to. The trails are in great shape just wish they where marked a tad better. Would do again if I was in the area.
The lower trails are great for families with young children. The walk to the base of the waterfall is about 10 min, 15 if you take your time. The trip to the top of the falls is an easy walk for seasoned hikers, moderate for those just starting. Beautiful view of casper once at the top. The stream is running it's fastest in early to mid spring and makes for a great picture oppertunity.
