Grand Canyon North Rim, Zion, Bryce Canyon

We spent a couple of days at both Bryce and Zion last spring. It was enough, but if you want more hiking (we don't do a lot) add another day each. One other item and I'm not sure if someone mentioned it, don't forget to go out the west side of Zion north to the Kolob Canyons area, still part of Zion and really nice. Half a day for that trip. While at Bryce, spend another half day or day to go to Kodachrome Basin State Park. It's about half an hour to 45 minutes away from Bryce. If you have a higher ground clearance vehicle than we did (2013 Fusion), you can go past Kodachrome into Escalante National Monument and on to the Grosvenor Arch. Another fun side trip is Coral Pink Sand Dunes State Park, between Zion and Kanab. It's a couple hour visit, but pretty and unusual. Just food for thought. Spectacular area of the country.
