Jacks Narrows — Thousand Steps

Climb the thousand hand-laid stone steps quarry workers once used to reach the top of Jacks Mountain. Climb a staircase quarry workers built straight up Jacks Mountain to reach the ganister-rock workings above Jacks Narrows.

This 2-mile out & back adventure in Juniata Valley / Mount Union is best approached as a real outing, not simply a pin on a map. The experience centers on Jacks Narrows — Thousand Steps, with the route and stopping points chosen to make the defining features accessible from the documented public starting point. Allow time to enjoy the setting rather than racing through it.

GETTING THERE & STARTING OUT Park only in the signed State Game Lands 112 Thousand Steps parking area along William Penn Highway. From the lot, use the established roadside trail approach and follow Standing Stone Trail markings to the base of the stone staircase. Climb the historic steps, watching for the numbered hundred-step markers. Continue beyond step 1,000 only on the marked trail toward the quarry remains, then reverse course and descend carefully to the same parking area. Your documented starting point is State Game Lands 112 Thousand Steps Parking Area. Use that access rather than navigating directly to a scenic feature, which may not have legal parking or a public approach. For driving navigation, the recorded destination is Thousand Steps Parking Area, 14559 William Penn Hwy, Mount Union, PA 17066.

THE ROUTE & WHAT TO EXPECT The recorded outing is approximately 2 miles with about 850 feet of elevation gain and is categorized as strenuous effort. The recorded time allowance is 1.5–2.5 hours. The route information describes the intended experience, not a guarantee that every segment is signed or maintained. Use the land manager’s current map and posted instructions to make decisions at junctions.

WHAT MAKES THIS PLACE SPECIAL Quarry workers built the steps to reach ganister rock used in the area's refractory-brick industry. The climb gains roughly 850 feet in less than a mile. Every hundredth step is marked, ending at the celebrated 1,000th step. The route is part of the long-distance Standing Stone Trail through Jacks Narrows.

LOOK CLOSER Once step 1,000 is behind you, continue far enough to see the old quarry landscape the workers were climbing toward. The staircase makes a lot more sense when you meet its reason for existing.

SEASON, CONDITIONS & SAFETY The trail is used year-round, but wet leaves, snow and ice make the steep stone staircase significantly more hazardous. State Game Lands hunting seasons require additional awareness. Relevant hazards identified in the source research include steep stone staircase, wet or icy steps, hunting activity, rocky terrain, roadside approach. Before leaving, check temporary closures, storm damage, snow or ice, parking availability, posted land-manager advisories. Dogs are recorded as allowed on leash; follow all posted rules and keep them controlled.

BEFORE YOU GO No permit or reservation is required for ordinary individual day use. Public hiking access to the Thousand Steps/Standing Stone Trail from the State Game Lands parking area is free; no day-use hiking fee is identified. Check current hours, trail or tour availability, and on-site signs before traveling. Bring appropriate water, footwear and layers for the terrain and forecast. Respect closures, neighboring private land and any protected natural or historic features.
