There are some nice trails out 285 past Bailey. One that starts right of 285 is Ben Tyler Gulch trail - if there's snow I was there Christmas Eve day and no snow, but may be now. Also if you drive up Guanella Pass Rd from 285 side there are a couple nice trails that start right at the campground where they stop plowing the road. There is one on each side of the road. I like going out 285 as you aren't dealing with the I70 traffic.
