When is the best time to visit or is December a perfect month? Also would I need any chains on my Sienna mini van wheels to get up to the snow mountain? Thank you!

Depends on weather. I would go right after a storm because that's when the conditions on the slopes are the best. But you should be prepared to bring chains. They may require it

Right now is the best time I went saturday had cable for my tacoma but didnt use them. They had the road closed but a grip of us moved the barriers and went through anyways. They have a storm coming through this week I believe wednesday and Thursday so this weekend would be a great time to go. They have 3ft of fresh snow right now. Had a blast both east and west resorts open. Best time to get there is by830 or 9 or you parking at east resort. West is the main and has the best runs with park and rails and boxes. Like Cassandra said have chains with you cause if you go up and they chp checks they will send you back down the mountain if you dont have them. Best of luck brotha and shred it up!🤙

Chains depends on current weather. Always carry them with you just in case. Now is the perfect time to visit as we just got a bunch of fresh snow
