Mary's Rock Tunnel

Overview

Carved straight through Blue Ridge granite, Mary’s Rock Tunnel (mile 32.2) is the signature drive-through moment on Skyline Drive. It’s short and sweet as an attraction, but undeniably cool—part history lesson, part photo op, and a fun pivot point for nearby hikes.

What You’ll See

You’ll drive 600-ish feet through jagged rock with a dramatic stone portal. Immediately south of the tunnel is the Tunnel Parking Overlook, an east-facing pull-off that lets you frame the tunnel mouth with the valley beyond—an easy place to hop out for photos without clogging traffic.

History & Engineering

Built in 1932, the tunnel was the biggest construction challenge on Skyline Drive, drilled and blasted through solid granite in about three months. A concrete lining was added in 1958 to reinforce the bore. It remains one of the park’s most recognizable manmade features.

Wildlife

This isn’t a wildlife hotspot, but the surrounding forested slopes are classic Shenandoah habitat. Keep an eye out along Skyline Drive for white-tailed deer, black bears, wild turkeys, and songbirds in the broader area.

How to Visit

• Use the Tunnel Parking Overlook immediately south of the tunnel for safe viewing and photos.
• Headlights on through the tunnel and do not stop inside—traffic can stack up quickly when drivers linger.
• If you’re pairing it with a hike, Marys Rock summit is close by via Panorama or Meadow Spring trailheads.

Best Time to Visit

• Weekdays or early mornings offer the calmest traffic and the easiest photos.
• The overlook faces east, so dawn to mid-morning gives flattering light on the tunnel and valley. Late afternoon brings shade on the portal but softer skies.
• Expect heavier traffic on fair-weather weekends and during peak fall color.
