Here is the display sign at Upheaval Dome Trailhead. We took the Upheaval Dome Overlook Trail. Hike photos 113-124. 9:30-10:40 AM. 1.8 mile hike. We could have done an 8 mile hike following the Syncline Loop Trail from this trailhead, but we chose to do a bunch of short mini-hikes instead which added up. I stick to that recommendation if you have only one day for this park.
