My friends and I road-tripped to Vegas, staying overnight and then continuing on to Zion, then Bryce, then two nights of backpacking in Capitol Reef, and finally ending at the Grand Canyon. It was quite the experience despite the pandemic, but it was still beautiful. The low for us in Capitol Reef on the Chimney Rock Trail came down to about 20F. Brrr! These three National Parks are easily accessible by car, just a few hours apart from each other.
