I did the two main loops that make up the Frosty Mountain 50k race route. Definitely a nice alpine course with lots of climbing!
The trails all are in great shape with only a few patches of snow, but not on any super steep areas (two sections on the Frosty ridge trail before the summit junction and some long, flat areas in the larch meadows). The ridge to the summit is clear and all of Skyline is as well (though there are blowdowns from previous seasons on both sections of Skyline).
The best part, besides the views, was soaking in the Similkameen River at the trailhead: it was ice cold and I only lasted seven minutes until I couldn't feel anything below my waist.
