I don't know what to say that hasn't already been said, you won't regret taking the hike. It's beautiful country!
We followed the directions (below) posted by HikingGirl_8. Thank you, it was a much prettier hike than trudging on the 4WD road. While we were there, on top of the bridge, was a woman with an infant in a front carrier. I wouldn't recommend this unless you're in good shape and have great balance. There are "stairs" built to get you to the top but it still takes some balance and strong legs.
From Dry Creek Rd, turn right onto Long Canyon Rd and go 0.3 miles to the Chuck Wagon Trailhead parking lot on the right side of the road. It is shared with the Mescal TH on the other side of the road.
Hiking out of the parking lot, at 0.2 miles, the Chuck Wagon trail forks – Go Left. After almost 1 mile, you will see a trail going off to the right at the sign “To Devils Bridge” – Follow that trail 0.1 miles to the Devils Bridge TH off of FR 152 (You will cross the road to get to the trailhead.)
