Cook Forest — The Forest Cathedral, the Fire Tower & a Clarion River Float
Two hours northeast of Pittsburgh stands one of the last great stands of virgin white pine and hemlock in the eastern United States — a cathedral of trees that has never known the saw. Cook Forest State Park protects the Forest Cathedral, a National Natural Landmark where old-growth pines soar over 180 feet, some more than 300 years old, in a hushed, green-lit grove unlike anywhere else in the state. Day one walks that ancient forest and climbs the historic Seneca fire tower for a view across the treetops and the Clarion River valley. Day two takes to the water itself: a lazy float down the gentle Clarion River and a walk of the rail-trail that shadows its banks, before the drive home. A weekend of giant trees, big rivers, and deep quiet.
