What January feels like
Cave Point is the winter attraction — spray freezes onto the cliffs and the shelf ice builds into ridges you can hear working. Newport State Park is a certified dark-sky park, and January nights out there are as clear and cold as they come, which is worth the drive on its own.
Winter is doing its thing: 15.6 in of snow in a typical January, with fresh snow on about 7 days. Nearly every night dips below freezing.
Can you swim?
The lake runs about 35° — frigid — locals in wetsuits only.
