The Tunnel, Warmer Than Outside
Blue Ridge Tunnel · 215 Afton Depot Lane
The tunnel holds 50 to 65 degrees every day of the year, which in February means walking into the mountain to warm up. The Parkway leaf traffic is months gone, the lots are empty, and the whole thing is free — 2.25 miles each way through an 1858 rail bore.
Unlit end to end, water underfoot, and the greenstone ceiling drips. A real headlamp and proper shoes, regardless of the season. No restrooms on the trail.
