You should always carry chains in Washington state you never know from day to day if it's going to snow a lot so better safe than sorry and I've traveled there a few times but with my 4x4 truck and it's worth going to, so go have fun 🤗
Not normally but you can always call for road conditions in the rare instance that we encounter lower elevation snowfall.
If alot of snow accumulates, yes. Check their website for road conditions before you head out there!
