In June, mulberries will be ripe for the picking. These delicious berries are not just a favorite of songbirds, foxes, raccoons, opossums, skunks and squirrels—humans enjoy them, too. Take a walk with a Naturalist along the Towpath Trail sampling these berries at the North and South Parking Lots. Meet at the South Lot trailhead. This program is part of the Park Rx series of programs sponsored by Highmark Blue Shield. Pre-registration required.
