Okay Super easy to find this parking lot
Take 23 North straight to High Point The parking lot will be on your left . It will say Appalachian trail parking lot.
Mark's cell[masked] AUTHOR'S NOTE: THIS ROUTE SHOULD NOT BE CONFUSED WITH THE APPALACHIAN TRAIL APPROACH FROM THE SOUTH THAT BEGINS ON ROUTE 23 NEAR THE ENTRANCE TO HIGH POINT STATE PARK.
From NY: Take I-84 Exit 2 and proceed south on County Route 55 (AKA Mountain Road). This road crosses into New Jersey approximately 3.3 miles from the Interstate and becomes Route 519 but keeps the Mountain Road moniker. The Appalachian Trail crosses the road approximately 2/10 of a mile into New Jersey. Park on the shoulder of the road.
From NJ: The State Route 23/County Route 519 split is located approximately 1 mile southeast of the entrance to High Point State Park. From this point, follow Mountain Road (County Route 519) north for 2.3 miles to the Appalachian Trail crossing. Park on the shoulder of the road.
