Prepare for AMS due to high altitude in Bryce. I didn't realize and we spent 2 nights up there, I lost appetite, feeling fatigue and a severe headache that pain killer didn't work. We did the UT 12 and visited the Mighty 5 (they are so close together so it won't take long to see them all). When we were there during Christmas there was a lot of ice on the paths and I slipped twice at the same place and got a big bruise as a souvenir that was on my bump for 6 months!
