The Citadel is a very cool ruin located in Road Canyon within Bears Ears National Monument. To get to the trailhead, you will travel down the 261 until you come to Cigarette Springs Road. Cigarette Springs Road is a fairly well-maintained road I was able to make it down in a Corolla. Just after turning onto Cigarette Springs Road you will come across a BLM sign asking you to pay $2 for a permit.
The first time I hiked The Citadel in 2009 it was difficult to locate, as there was very little information about its location on-line. After eventually tracking down its GPS coordinates, I just drove down Cigarette Springs Road until I got close and followed my GPS to them. However, when I visited again in 2013, there was a road leading north from Cigarette Springs Road to a parking area near the rim of Road Canyon. It appears people hiking The Citadel now just park here and follow the trail along the rim of Road Canyon. I've found that once a spot in southern Utah gets popular enough, the BLM will often concede and add a trail to prevent people from getting lost or causing damage to the surrounding landscape trying to find it.
The only way to The Citadel is by crossing a long land bridge jutting out into Road Canyon from the west. Near the beginning of the bridge, keep your eyes peeled for some granaries. You will need to scramble a bit to find a good route down to the bridge and once across, back up to the The Citadel. These are some very well-preserved dwellings located high on a cliff overlooking Road Canyon.
