A short walk through a manmade tunnel is the highlight of this unique, family-friendly trail located just 20 miles east of Zion National Park. The cave-like tunnel/Belly of the Dragon was originally created as a water culvert under HWY89 but over time drainage from upper canyon water flow has carved the sandstone walls and created a beautiful rippling tunnel prime for exploring. This is such a great adventure with kids so bring the whole family and have some fun!
