Use sunset as your turnaround alarm.
A natural bridge is not an arch. A bridge is cut by running water, and standing under Hickman's 133-foot span you can still read the drainage that did the work. The trail climbs steadily away from the Fremont River for the first stretch, which is the part that catches people expecting flat, and then levels out at the bridge. Trailhead parking on Highway 24 fills by around 9 am and stays crowded until after 4 pm, so go early or go late.
133 ft natural bridge; pair with pie from the Gifford House. Yes, pie.
2 liters water, trail shoes, sun layer, snacks, small first-aid kit.
