Zion is great. Note that you can only access the valley by shuttle bus. When I went (Spring 2018) the buses were packed and it took an hour in line to get in.
I suppose if they reopen they’ll have the ‘safe distancing’ protocols in place, whatever that means.
Wow, that’s sad to hear about Zion. Went there as a kid on family trips in the 60s and the place was deserted. Went there in the early 70s when I had left home and was working at my first job. It was still nearly empty.
