The Pittsburgh to Washington, DC bike trip is really two trails stitched into one journey. You start at Point State Park in Pittsburgh, where the Great Allegheny Passage begins at milepost 150, and follow the old railroad grade 150 miles southeast to Cumberland, Maryland. There, at GAP milepost 0, the trail hands you off to the C&O Canal Towpath, which carries you another 184.5 miles along the Potomac to Washington. Total: 334.5 miles, none of it shared with cars.
Most riders break the trip into five to seven days, and the pacing question everyone asks is the same: where do I sleep on the mountain? The GAP crests at the Eastern Continental Divide — 2,392 feet at milepost 23.5, the highest point on the trail — and how you handle that summit shapes your whole itinerary.
That is where Frostburg comes in. The Tunnel Hotel sits 300 yards off the trail at GAP milepost 15.9, an 1888 stone-arch railroad inn built into the grade itself. For eastbound riders, it is the classic night-three-or-four stop.

Why Frostburg Is the Classic Night 3 or 4
Riding east from Pittsburgh, the GAP climbs gently at railroad grade — roughly 1 to 1.75 percent, never steep — until you top out at the Eastern Continental Divide. Frostburg, at milepost 15.9, is the last real bed before that summit push if you are still climbing, or the first one after it if you crested earlier in the day. Either way, the geometry of the trail funnels multi-day riders through this town at almost exactly the same point in their itinerary.
Time it so you sleep in Frostburg after crossing the Divide and the reward is enormous: 16 miles of continuous downhill coast into Cumberland waiting for you in the morning. You will barely pedal.
Eastbound riders also get the scenery in the right order. Big Savage Tunnel — about 3,300 feet long, lighted, at roughly milepost 22 — comes just before the Mason-Dixon Line crossing at milepost 20.5, and both sit within the last stretch before Frostburg.
How the Route Breaks Down
The GAP half is crushed-limestone rail-trail with that signature railroad-grade profile: long, gradual, predictable. From Pittsburgh you gain elevation slowly for days, cross the Divide at MM 23.5, then drop into Cumberland at around 627 feet. It is the kind of climbing you notice in your average speed more than your legs.
The C&O half is a different animal — an unpaved canal towpath, generally flat, running 184.5 miles from Cumberland to Washington past historic locks and through the Paw Paw Tunnel. The surface is rougher than the GAP, so many riders plan slightly shorter daily distances on the towpath even though the terrain is easier.
A five-day trip means long saddle days; seven days leaves room to linger in trail towns. Wherever you land on that spectrum, Frostburg at MM 15.9 falls naturally near the route's midpoint milestone — the summit — which is why it anchors so many itineraries.
Built for Riders Rolling In Late
The Tunnel Hotel runs 24-hour contactless check-in: your door code arrives by SMS, so a flat tire or a slow day on the trail never means a dark lobby and a locked door. Checkout is 11:00 AM, late enough for a proper breakfast before the descent.
The Trail Inn Cafe is on site with coffee, hot breakfast, trail sandwiches, and local beer, all chargeable to your room — useful when your wallet is buried in a pannier. Rooms start at $69.99 for the Little Savage Sleeper and Queen City Sleeper, and groups can take Braddock's Bunk Room (sleeps 4) or the Big Savage Bunk Room (sleeps 6). Twenty-plus primitive tent sites at $15 per person, including an ADA site, cover riders who packed camping gear.
Book direct at /book — Stripe-secured, no online booking fees. The cancellation policy suits trail plans that shift with weather: cancel 72 or more hours out for a full refund, reschedule with 48 hours' notice, and if the operator cancels for weather you choose a refund or credit.
The Town at the Top of the Grade
Frostburg is a working railroad town, not a museum piece — though it has one of those too. The Thrasher Carriage Museum is next door to the hotel, and the Frostburg Depot with its turntable sits adjacent. Watch the Western Maryland Scenic Railroad's Frostburg Flyer, pulled by steam locomotive 1309, arrive at 12:45 PM and turn around for its 2:15 PM departure.
Downtown — shops, dining, breweries — is up the hill, and Frostburg State University keeps the town lively year-round. If you build in a rest day, Tracks & Yaks at 19 Depot St runs pedal-powered railbikes on the old grade beside the hotel, with trips from $89 per tandem railbike.

How many miles is the bike trip from Pittsburgh to DC?
334.5 miles total: 150 miles on the Great Allegheny Passage from Pittsburgh to Cumberland, Maryland, then 184.5 miles on the C&O Canal Towpath from Cumberland to Washington, DC. The two trails meet at GAP milepost 0 in Cumberland, so the transition is seamless.
How many days does the Pittsburgh to DC bike ride take?
Most riders take five to seven days. Five days means big-mileage days on mixed surfaces; seven days gives you time in the trail towns. Frostburg at GAP milepost 15.9 typically falls on night three or four of an eastbound itinerary, right around the Eastern Continental Divide.
Is the GAP trail hilly riding from Pittsburgh?
It climbs, but at railroad grade — roughly 1 to 1.75 percent, never steep. Eastbound from Pittsburgh you gain elevation gradually to the Eastern Continental Divide at 2,392 feet (milepost 23.5), then descend about 24 miles into Cumberland at roughly 627 feet.
Where should I stay near the Eastern Continental Divide?
Frostburg, Maryland is the trail town closest to the summit — The Tunnel Hotel at GAP milepost 15.9 is 300 yards off the trail, about 7.6 miles below the Divide. Sleeping there after cresting means you start the next morning with 16 miles of downhill into Cumberland.
Is Big Savage Tunnel open year-round?
No. The 3,300-foot lighted tunnel near GAP milepost 22 closes in winter, roughly late November through early April, and there is no easy detour. If you are planning an early-spring or late-fall Pittsburgh to DC trip, verify the seasonal closure dates before you commit to an itinerary.
