I’ve stayed at Site 1 twice in the winter. We did manage to hike in on a blizzard night in November of 2019, but the park office made sure we were ok. The park office has limited hours so be prepared with firewood ahead of time. They do not plow the campground parking lot in the winter, but they do plow down to the pebble beach lot. You can snowshoe, hike, or toboggan in. The back trail off Of pebble beach parking is groomed and has views of the light house and nature center. There is a dumpster and a bathroom that is open. There is another bathroom off of the campground parking lot that I was able to use, but you will need to have snow shoes. Camping at site 1 in the winter is amazing. Perfect views of the lake and lighthouse. The site is protected from the lake by a large hill that has a bench at the top. The site has a picnic table, bear box, and grate. During the summer, the site would have a lot of noise from the parking lot and hiking traffic. In the winter, there are a lot of photographers. There are coyotes in the winter.
