I'll be visiting these, probably in this order: * Salt Lake City airport * [Zion NP](http://wikitravel.org/en/Zion_National_Park)     4-9k ft altitude * [Bryce Canyon NP](http://wikitravel.org/en/Bryce_Canyon_National_Park)     6-9k ft altitude * [Capitol Reef NP](http://wikitravel.org/en/Capitol_Reef_National_Park)     4-9k ft altitude * [Canyonlands NP](http://wikitravel.org/en/Canyonlands_National_Park)     4-7k ft altitude * [Arches NP](http://wikitravel.org/en/Arches_National_Park)     4-5k ft altitude * Salt Lake City airport If I were going to skip one, it should be Canyonlands, as that has the lowest number of visitors. The reason for this order -- Zion park has almost double the number of visitors as Arches.
