I don't and cannot possibly have the words to describe the beauty of Zion. Just come and experience it for yourself. You must.
I can't believe this place isn't a National Monument or some kind of protected area. Thankfully, it is remote, remains beautiful, and awe inspiring to take in.
I'm sure it can be rather crowded during the spring and fall when temperatures are more comfortable, but I went in late December, and the silence, vast openness, and serenity was a very spiritual experience.
With so many places mixing snowboarders and skiers on the same runs, it's very refreshing to be in Alta -- a place for skiers.
I enjoy snowboarding as well, but skiing is a much quieter experience, and Alta is happy to accommodate with its beautiful runs and views, along with the almost always perfect snow conditions.
If you want a quiet break away from Park City and Snow Bird, go ski Alta.
We visited in late December. The nice and snow made for an interesting entry with our Navajo guide and 4WD truck. But man, was it worth it! Our guide gave us history lessons as he suggested routes for us through the tricky terrain.
I believe you can also hike down to the ruins for free, and there are group tours you can take on large 6-wheeled behemoths. However, I wouldn't have traded my private tour experience for either.
