Long trail for sure. Beautiful scenery and abundant wildlife. One young bison wanted to play chicken on the trail. He won. Didn’t see another soul until 7 miles in Lots of sand early on and little mud. Loose rocks can make it a challenge. A sturdy walking stick helps tho. If you go in the summer start early. I headed out at 0700. 3 liters H2O was just about right even with temps in the mid 90s. Will definitely be back Next time will take Haynes Overlook for the return.
