The Powerlinez are a somewhat recently opened area within Harriman State Park. Located in the Southwest Corner, visible from I-87 North just past exit 15 (Mahwah/Paramus), they offer traditional and sport climbing routes up to 100' tall.
The Powerlinez are probably the nearest cliffs now to NYC, and with their aspect offer great climbing and bouldering in the colder times of the year. Come out for a day or two with us to explore and get to know a new area.
The guidebook is available at Rock and Snow.
