From Baltimore take 95 S to 495 W heading toward Northern Virginia. Travel over the top of the DC beltway and you’ll pass Holy Cross Hospital and the Mormon Temple. Exit on to the 270 N spur toward Frederick. Take the first exit (Exit 1) on to Old Georgetown Road and bear right. Turn right on to Old Georgetown and get immediately into the left lane. At the next light turn left on to Tuckerman Lane. Stay on Tuckerman and you’ll pass under 270 and you’ll pass Westlake Drive. The campsite is on the righ -- there is a brown sign, a bridge, and a gate. Cross the bridge into the site and park on the upper parking lot.
