If you are up for an adventure, you could always go hike up a 14er ! The access to Mt Bierstadt is very easy, and after that it is a straight forward 'hike' up to 14K. The summit has lots of boulders and scree, but nothing at all technical.
With the amount of snow, there still might be some up top (just kidding!)
You could also go hike and ski a glacier, St. Mary's is just up I-70 as well.
2nd a 14er...and agree Bierstadt is a good first one. Evans is also really easy from Summit Lake.
