The 93rd New York Infantry Monument is located on the right or west part of Taneytown Road/Route 134 if traveling south, at the intersection of Taneytown Road (State Highway 134) and Hunt Avenue. The monument is located on a walking trail extending between Cemetery Ridge and Meade's Headquarters, near the Leister House. The paved trail leads to the High Water Mark. The front of the monument faces south. There is a fence directly to the side of the monument. 
Parking is available at small, cutout shoulders along the road, some wide, some narrow. Be sure to stay off the grass or you will be ticketed by park police. Also, do not park on Taneytown Road; there is parking available along Hunt Avenue. I visited this monument on Tuesday, August 7, 2012 at approximately 4:16 P.M. I was at an elevation of 578 feet, ASL. I used a Canon PowerShot 14.1 Megapixel, SX210 IS digital camera for the photos.
