Join the Friends of Cook Forest as we take a 6.5 mile strenuous interpretive hike ((sometimes off-trail) to the Hogback, a peculiar horseshoe curve and steep razorback ridge where the picturesque Clarion River wraps around you along the Tobecco Trail.  If time permits we’ll measure big pitch pines on the hilltops and the park’s largest cucumbertree 350ft down at the valley floor.  Pack a lunch & water.  Please meet at the Park Office where we’ll drive to the starting point.
