Fall colors are ablaze and the towpath along the Potomac River is one of the finest places in the D.C. Metro area to experience this season’s richness. In order to cover more territory and visit more habitats, we’ll use bikes to explore the stretch from Swain’s Lock to Blockhouse Point, a 9-mile round-trip ride. We’ll dismount often to look for fall fruits and admire lingering fall blooms while we watch and listen for all manner of wildlife, including birds, butterflies and other insects, turtles and more. Bring your own bike. REGISTER
