The lake and road at Pilot Knob State Park were groomed for both skating and classic skiing early this morning. The road had quite a few soft drifts, but after 6 passes with the Ginzu groomer it should be a great ski.
Best place to access the road is to park at the Northwest park entrance. The road is about 1.9 miles(3.1 km) from that gate to the other end of the park. One out and back loop would be 3.8 miles (6.2km). And you have miles of ungroomed hiking trails to explore that connect to the road.
Best place to access the lake trail is to park in the sledding hill parking lot and walk/ski directly south and there you'll find a 1.5km loop.
