Visiting Zion and/or Death Valley NP in early January 2020

We hit snow in Zion in January. The road up from the canyon is steep and winding. I think it can be closed if there is bad weather but I’m not sure.

There can be snow heading out of Vegas on 15 at higher elevations. I’ve not seen much though. I’d check the 15 day forecast.
Zion is at 3000 feet.
Joshua is nice but a little on the boring side for me.
I can’t remember what it was like going to Death Valley from Vegas but our exit was definitely up a steep hill to the west. We were young and dumb. Our car overheated but there were water stations on that hill. It was August!

If you had looked just five days ago this same question was asked.

I spent nearly a week in Death Valley between Xmas and New Year some years ago and it was excellent. I drove from the Peninsula (back when I lived there), took a detour to visit King's Canyon and Sequoia, then drove past Mono Lake. I don't mind driving long distances and I like having my own car, partly because I hate the hassles of flying, but also because it's cheaper. Also, if you drive, you can adjust your route to last-minute weather conditions. Do check what accommodations are available before you book a flight. A lot closes up for the winter.

In the valley, I got up before dawn to drive up one of the surrounding mountains to watch a sunrise and it was very cold. Then I drove back down to do some hiking in the valley and started shedding clothes. By 10 am I was in short sleeves.

Thanks for the replies. Looks like it could be a little questionable to try for Zion. Not an area to learn to drive in the snow, any more than you want to learn how to drive a stick shift on your vacation to England.

This recent thread may be helpful, at least parts of it. That poster is looking at driving at higher elevations to Bryce and Grand Canyon, which most responders discourage. But your situation is different. I'd be very surprised to encounter snow requiring chains between Vegas and Zion Canyon, or between Vegas and Death Valley. Ice might be more of an issue, especially early in the morning before sun hits roadways that might have had light rain or snow the day or night before.

Actually, with rain coming thru the area, flash floods are more of a problem. They have snow in Flagstaff and Williams, which would cover the south rim of the Canyon, I doubt you'd need chains, but tires are more important, and I never trust rental cars to have the best.
