Afton Mountain hides a 4,273-foot tunnel and Virginia lets you walk every inch of it

The Claudius Crozet Blue Ridge Tunnel

Central Virginia hides a train tunnel you can walk straight through.

The Blue Ridge Tunnel cuts under Afton Mountain near Rockfish Gap, running 4,273 feet end to end, close to eight-tenths of a mile. Trains rumbled through here for decades.

Today the crushed-stone trail stretches about 2.25 miles from one trailhead to the other, and instead of a locomotive, you’re the one making all the noise.

Somewhere past the entrance, the light behind you fades out completely.

Workers Carved This Tunnel by Hand

French-born engineer Claudius Crozet planned the tunnel in the 1850s. Workers cut the rock by hand with drills and black powder.

Irish immigrants made up most of the crew, and enslaved African Americans were forced to work alongside them. Many died, including some lost to a cholera outbreak in 1854.

Two crews dug from opposite ends and met in 1856, missing each other by inches.

The tunnel opened in 1858 as the country’s longest railroad tunnel, and trains ran through it until 1944.

Total Darkness Waits in the Middle

The tunnel has no lights anywhere inside, so bring your own.

A strong flashlight or headlamp makes the walk manageable, and without one, the middle stretch turns pitch black in every direction.

Some hikers stop right there, click off their light, and stand in the dark for a minute just to feel it.

Look toward either end and you’ll spot a small dot of daylight glowing far off, proof that you’re still headed somewhere.

Why Locals Call It the Coolest Hike

Step inside and the air temperature holds in the 50s no matter the season.

On a hot Virginia summer day, that steady chill feels like relief the moment you cross the threshold. In winter, the same air can feel almost warm compared to the cold outside.

Locals settled on a nickname that fits: the Coolest Hike in Virginia. Even in July, you’ll be glad you grabbed a light jacket or a sweater before heading in.

Two Entrances, Two Different Looks

The tunnel’s east entrance looks like a raw cave, carved straight into bare mountain stone with no dressing up.

Head to the west side and the portal looks entirely different, faced with cut limestone, and about 1,400 feet of the interior near that end is lined in brick.

Both openings rise around 20 feet above the old track bed, and a wide, curved stone arch stretches overhead at each one. Walking from one entrance to the other, you pass through two completely different builds.

Bats and Bright Orange Salamanders

The cool, damp air inside makes the tunnel a shelter for small wildlife. Look up near the ceiling and you might spot bats resting in the dark.

Near the water on the floor, bright orange salamanders sometimes show up, and crayfish turn up in the shallow puddles that collect along the path.

Move slowly and keep quiet, and you’ll likely notice more creatures than you expected to find inside a train tunnel.

Water Drips Through the Whole Tunnel

Water drips from the ceiling and walls year round, no matter the season you visit.

In places, small streams trickle straight down the rock, and puddles collect on the tunnel floor, so your shoes will likely get wet before you’re through.

Near the bright openings at each end, green vines hang down over the stone.

The whole way through, that steady drip echoes softly off the walls, filling the quiet with a small, constant sound.

Read the Marks Left by 1850s Tools

History signs stand along the trail and near both entrances, laying out how workers cut through the mountain using nothing but hand tools.

Look closely at the rock and you can still find pin scars left behind by drills more than 160 years ago. A marker along the way names the tunnel a National Historic Civil Engineering Landmark.

Between the signs and the scars in the stone, you get a clear picture of what building this took.

Real Trains Still Run Right Next Door

On the eastern stretch of trail, you walk alongside a live railroad line that’s still very much in use.

A newer tunnel replaced this one back in 1944, and real trains keep rumbling through the mountain just next door to the path you’re on. Along the way, the trail opens up to views of the green Rockfish Valley below.

Standing between the old tunnel and the new one, you can see exactly how travel through these mountains changed.

Track Chairs Open the Tunnel to More Hikers

The eastern side of the trail runs flat and even, built to be easy for almost anyone to travel.

That stretch is considered wheelchair accessible starting from the Afton trailhead, and free motorized track chairs are available for hikers with limited mobility.

A local partnership began offering guided track-chair trips in 2025, opening up the walk to people who couldn’t have managed it before. The whole point is letting more visitors experience this stretch of mountain.

Bring the Whole Family, Dogs Included

The gentle grade on the east trail makes it a solid pick for a trip with kids or grandkids in tow. Leashed dogs are welcome the entire way, both on the trail and inside the tunnel itself.

Bikes are allowed too, though most riders end up walking theirs through the darkest stretch. Kids tend to love the echoes, the dripping water, and the glow of daylight at each distant exit.

Most families come out the other end feeling proud of what they just did together.

A Mountain Walk Unlike Any Other

Not many places let you walk straight through solid mountain rock and come out on the other side.

This tunnel packs history, wildlife, and a bit of real adventure into one short trip, and it sits close to both Skyline Drive and the Blue Ridge Parkway.

The dark, cool passage doesn’t feel like a normal hike at all.

Plenty of visitors leave saying they’ve never done anything quite like it anywhere else in Virginia.

Walk the Blue Ridge Tunnel, Virginia

You’ve got two ways in: the East Trailhead at 215 Afton Depot Lane in Afton, or the West Trailhead at 483 Three Notched Mountain Highway in Waynesboro. Afton has the bigger lot and an easier walk.

The trail stays open year round from sunrise to sunset at no cost.

Bring a flashlight, wear shoes that can get wet, and carry water, since restrooms are portable only. A round trip covers about 4.5 miles and takes up to two hours, but you can turn back early.
