The GAP Trail Through Pennsylvania — and the Ride Into Maryland

Milepost 23.5 is the Eastern Continental Divide — 2,392 feet, the highest point on the entire GAP. Southbound, this is where the long Pennsylvania grade finally pays out; everything from here to Cumberland is downhill. Water on one side of this ridge heads for the Gulf of Mexico, water on the other for the Chesapeake, and you pedal over the seam.

Around milepost 22 comes the Big Savage Tunnel: roughly 3,300 feet of bore through the mountain, lighted inside, and genuinely unforgettable — a long minute of cool air and a pinprick of daylight growing ahead of you. One planning note that trips riders up every year: the tunnel closes for winter, roughly late November through early April, so check the seasonal dates before building a shoulder-season itinerary around it.

Then, at milepost 20.5, the Mason-Dixon Line. A few pedal strokes and Pennsylvania is behind you. From the border marker it's about five trail miles of descent to Frostburg at milepost 15.9 — which is why so many southbound riders who cross the line in late afternoon make Frostburg the night's destination almost by physics.

The Tunnel Hotel has been putting travelers up beside these rails since 1888, and the setting still reads pure railroad: the Frostburg depot and turntable adjacent, the Thrasher Carriage Museum one door over, and — if your timing's right — the Western Maryland Scenic Railroad's Frostburg Flyer steaming in behind locomotive 1309 at 12:45 PM, departing 2:15 PM. "Sleep by the rails" isn't marketing copy here; it's geography.

Riders coming off Big Savage rarely arrive on a schedule, so the hotel doesn't keep one: the door code comes by SMS and works at any hour, no desk clerk required, no penalty for rolling in at dusk. The Trail Inn Cafe sits on the property with coffee, hot breakfast, trail sandwiches, and local beer — all chargeable to your room, so the wallet stays buried in the pannier. Downtown Frostburg's restaurants and breweries are a walk up the hill when you've got the legs for it.

Flip the direction and Frostburg earns its keep a second way. Northbound from Cumberland (elevation around 627 feet), the GAP climbs on steady railroad grade — about 1 to 1.75 percent — for 16 trail miles to Frostburg, then keeps rising to the Divide at 23.5. Sleeping here splits that climb: knock out the lower half, rest, then take the Divide and the tunnel fresh in the morning as your send-off into Pennsylvania.

You can also let machinery do the first pull. The Bike Train puts you and your bicycle on the WMSR from Cumberland up to Frostburg for $45 bring-your-own or $49 with a rental — a steam-assisted head start on 16 miles of grade. The Great Deal Passenger Shuttle covers 25 miles for $39 to $49 when you need a car-position solution instead.

The rider-friendly picks: Little Savage Sleeper and Queen City Sleeper are queen rooms at $69.99 for two, and Braddock's Bunk Room sleeps four from $119.99 — the group-ride favorite. Layover day in Frostburg? Tracks & Yaks (19 Depot St, 301-349-3699) runs railbike trips on real track, including the 2-hour Helmstetter Hotshot at $99, and rents geared bicycles by the day for $40.
