Was only in Zion for a day in the beginning of June 2013. My only regret was that I didn't have more time in the park. It was one of my favorite National Parks.This drive is incredible! Truly a Can't Miss! Emerging out of the tunnel into the oasis of the park was beautiful. Winding down the switchbacks was a little scary (just take it slow) but so worth it! We ended up leaving through this entrance as well just so we could do the drive again.
