Welcome to Zion National Park! Entering the park from the Zion Tunnel descending these switchbacks offer the first view into Zion Canyon. Unfortunately due to safety concerns you are not allowed to bike through the tunnel, but emerging from the tunnel down these switchbacks provide a breath taking introduction to the park! If you're thinking about biking (up and then down) the switchbacks take a look at the dashboard below to get a sense of the adventure before you ride!
