Rock Glacier Trail
This is a very short trail - good for stretching your legs if you've been driving for a while. The trails generally just climbs, so it does take some basic level of fitness or just lots of breaks. The higher you go up the slope, the rougher the rocks get, and they can roll under your feet, so good footwear is advised.
The trail starts in the trees, and some swampy sections are avoided with a well-maintained boardwalk. Right at the foot of the rock glacier, there are stairs to get up a steep section. As soon as you're out of the trees (which is pretty quickly), you get beautiful views of Dezadeash Lake and the surrounding mountains. Some people have built seats out of the stones so you can sit and bask in your surroundings!
I'm not sure exactly where the end of this trail is - it just kind of fades out as you get higher up the slope. Ambitious hikers can climb way up the slope for great views.
