Cross-Country Skiing in Pennsylvania: Where the Trails Are

6 trail systems in Pennsylvania say on their own pages that a machine goes on the trail, and the ones that publish a figure add up to 56 km. Denton Hill State Park, run by Pennsylvania Department of Conservation and Natural Resources, is the largest of them at 29 miles (46.7 km). Another 2 places name ski trail without saying it is groomed.

Pennsylvania runs no single statewide ski pass. 2 of the 8 systems here charge for one, each on its own terms, and the rest ask nothing at the trailhead.

Pennsylvania Department of Conservation and Natural Resources publishes one report covering the state, State Parks Winter Report, and 8 of the 8 systems are on it. Where a club or a park posts its own grooming log, that log is the faster of the two.

The state does not print opening or closing dates; its parks report through the winter from the first snow to the spring thaw and groom when conditions allow. That is Pennsylvania Department of Conservation and Natural Resources’s own framing. Grooming is set by snow depth rather than by a date, so a system can sit idle inside its own season and run past the end of it in a good year.

A groomed trail has had a machine over it: the snow is compacted and, on most nordic trail, a pair of parallel tracks is cut into it for classic skis, with a flat lane beside them for skating. An ungroomed trail is whatever the last skier and the last storm left. Both are worth skiing and they take different skis, which is why these pages say which of the two a manager is claiming rather than counting every ski trail as the same thing.
