It was not that cold right after Thanksgiving, except at higher elevations. My friend and I hiked amongst the hoodoos in Bryce Canyon in the sun. It was pleasant enough not to need a jacket.

But as I said, once snow falls, they'll either close a number of the trails (Bryce Canyon), or they'll keep them open but you'll be walking on ice (Arches).

I saw Arches only when there was ice, and it was still totally worth it!
