The trailhead begins behind St. Alphonsus Rodriguez Church on Old Court Road and turns south past what was Woodstock College and down to the Patapsco. We then turn west along the river and up into the hills eventually looping around and back to the church. Approx. 600 feet of elevation. There will be a 20 minute lunch break. Pace 2.5 mph. LEAVE: 9 a.m. from the St. Alphonsus Rodriguez parking lot to the right of their school building.
