Chasm Lake
This hike follows the Long's Peak trail for the first 3 miles or so, then splits off toward the lake. The views are incredible throughout, passing pools and waterfalls along the way, with the lake sitting at the base of the Long's diamond. We had the trail mostly to ourselves all morning, and were even alone at the lake for a little while.
