This hidden gem is a MUST DO, if you happen to be in the Sedona area...
To get to the trail head drive about 3mi to the west from the 89A/ 179 intersection (the "Y") in Sedona, then turn R onto Dry Creek Rd. Drive about 3 miles out and be on the lookout for a sign that says "Red Rock Day Passes" on the right side of the road. Turn into this and find a vending machine, where you can get a day pass (parking permit) to hike in sedona. After this point, the trailhead is about 1.1mi, in and the road is rough (off-road). We chose to park and walk to the trailhead, but, some others were driving. The trailhead shows up on the right side as well. The hike itself is easy to moderate.. only the last part is very steep and you have to scramble up to get to the bridge. The most intersting thing, is that the bridge isn't visible till the very end (I almost thought, the bridge was covered in brush or something, and nearly gave up). Overall a very rewarding hike for relatively minimal effort, but, definitely not for someone with a fear of heights!
