Easy

Visit a lesser-known treasure of Harriman State Park on this 5.7-mile jaunt, which contours through hilly hardwood forest and along cascading creeks to a few peaceful ponds.

This 5-mile loop meanders along coastal bluffs and into wetlands in the heart of one of the finest birding spots in the United States.

Snowshoe into a small mountain lake on this gentle, 5-mile out-and-back in Indian Peaks Wilderness--a perfect winter getaway from the city.

Beautiful hike up through aspen groves and across meadows to Opal Lake.

This easy mile and a quarter loop gets high enough to get a nice view of Boulder, and lots of linking trail options easily lengthen the hike.
