Zion is beautiful but crowded. You now have to take a bus into the park instead of your own car. You park at a welcome center type of place and take buses into the attractions. I understand the need but to me it takes away from the experience.
If you want peace/solitude/nature, take the drive up Interstate 15 to the Kolob Canyon section of the park. There is about a 10-15 mile twisty road up into this section but the beauty/peace and great hiking opportunities make it well worthwhile.
