We did this early spring. Hiking along the river was a really pleasant hike. We did see a rattlesnake that curled up on the trail. Had to wait a while for it to calm down. When we started heading up as you can see in the bottom part of the gps track, it got a lot steeper. We got to see the biggest bull elk I've ever seen as well as a heard of cow elk along with several deer. Very pretty trip especially along that river.
