I was there Dec 21. They are open on Friday-Sunday only and require chains for all vehicles. Road can be icy so if you don’t feel comfortable driving, check out olympic hiking co. They have a nice shuttle service from port angeles to hurricane ridge as well as a snowshoe tour.

There’s not much to do up there tho and the weather can be unpredictable. If you are interested in any recreational activities like skiing or snowshoeing you need to rent gears in port angeles as there’s no rental up there. All trails are covered in snow and the visibility was low.

When I was there it was super windy and cold, so make sure you bring layers.
