The Trailside Boulder, a glacial erratic sitting all by itself along the Chicago Lakes Trail, hosts a number of moderate to medium grade problems, a few of which are quite nice but don't get much attention because they are mostly moderates. This is an excellent place to warm up in the morning or to make one more stop in the afternoon.
Park at the Echo Lake Picnic Area. Follow a nice gravel path to the west side of the lake, where a signed trail for the Chicago Lakes heads off to the southwest. Follow this trail for a few hundred yards over a ridge, into the Chicago Lakes Basin. The trail traverses along the valley wall for a while, and then drops steeply towards the valley floor, through a series of switchbacks. Once at the valley floor, the trail crosses a creek via a backcountry bridge, then joins an old dirt road.

A borderline-impossible-looking sit start on a jug below is obvious, but intermediates and feet to bridge the gap are sparse ... to put it mildly....[more] Browse More Classics in CO
