Can you over night camp in January here?

The camping area (airfield side) is closed in January. Same for Lyman Run, the nearby park with larger facilities. The Astronomy Field is open all night, but you must observe rules like using red light. The park is administered by Lyman Run State Park. Call the park office during the week to speak with a ranger and get full details. Numerous campgrounds and rustic cabin rentals, in addition to motels and bed and breakfasts are available throughout Potter County. Be aware that any reservations during peak hunting and fishing seasons are harder to find and will cost more.

You should be able to make reservations with them, but be sure to talk to the officials before making any solid plans.

Talk to state park office, dress warm.
