In addition to my previous post about Mt. Evans, there is a nice stop on Mt. Evans called Mount Goliath Natural Area that offers a walk through sub-alpine gardens and weathered bristlecone pines that are hundreds of years old. Pretty cool.
After Mt. Evans we went to St. Mary's Glacier, where you can sled, snowboard, or just slide yourself down the glacier. There were many people there sliding down in garbage bags. I tried going down on a "magic carpet" sled and totally lost my sled halfway down- still fun! Then, down in the lake, you could see people were jumping off the high rocks into the water. So much fun to be had surrounded by intensely beautiful views!
