Lower Merion High School.
315 E. Montgomery Ave Ardmore, PA 19003
Turn off of Montgomery Avenue using the driveway on the School House Lane side of the high school property (traffic is one way around the high school). That's on the far west side of the property (as you face the high school it is to your left towards the Suburban Square Mall). Going west on Montgomery Ave. there is a small directional sign that says "Pool Parking". Unfortunately, you can't see the sign going east on Montgomery Ave. Drive to the back of the building, park in the rear lot and enter the door under the "Natatorium" sign.
