September 18, 2018 - Unfortunately, it appears the aspen are caught between the early-changing trees getting their leaves blown way and the later trees not yet having changed. This probably isn’t a good weekend for enjoying the aspen in Rocky. However, there is definitely color do be found and in a week or two, some big areas will be changing.

Last year at this time was kind of ideal: Hidden Valley, Bierstadt Lake Trailhead were all recommended. This year, Hidden Valley’s aspen are well past-peak, and Bierstadt Lake Trailhead’s magnificent hillside is still yet-to-change.
