Parriott Mesa is the large mesa at the entrance of Castle Valley. It basically sits at the corner of River Road and the road into Castle Valley. Despite having a fair number of crack climbs and an easy 5th class scramble to the summit, it sees little traffic. The rock is quality Wingaye and there is a lot of potential for new routes.

Crooked Arrow Spire, which is an attractive semi-attached spire, is visible on the NW corner of the mesa. 

Approaches depend on the route you're climbing. For Crooked Arrow Spire and the Supernatural area, follow the high-clearance dirt road into Sister Superior (departs from River Road just north of the road into Castle Valley near a bridge). Stop before reaching Sister Superior near a huge, obvious boulder on the south side of the road. Follow a seldom-travelled trail directly past this boulder and up a ridge towards the north face of the mesa. Allow an hour for the slog. Other areas (Ascended Yoga Masters, etc) are approached differently.
