zion to boulder
 

How long would it take to drive from zion to boulder with a minimal amount of stops? will do stops on the way back, when we plan to stop at bryce for an overnight and day.

This will be the last week in April.

Boulder, Utah or Boulder, Colorado?

Boulder, Utah is about 145 miles and should take about 4 hours, not including your short detour to Bryce Canyon. Boulder, Colorado is about 660 miles going back to I-15 then up to I-70 and across. That trip should take about 11 hours. Going by way of Bryce and out throught the eastern Utah desert will be a few miles shorter but will take longer because of the lower speed highways. None of these estimates include the inevitable stops for dramatic views on both routes.

I neglected to mention both of those distances are from the Visitor's Center inside the west gate.
