This is the best place to watch the sunset in Sedona. You can start at Airport Saddle trailhead if you are lucky enough to find parking there, or start from other trailheads if there are more parking spaces. Anyway, you should hike to the summit, not difficult. You will be rewarded by the best sunset and view from either side. The alternative is to drive to the Sedona airport overlook, you pay $3 for parking, still you need to go early, otherwise, there's a long line of cars waiting to get parking, you may missed the sunset. However, the view is not as good as the previous spot. You can see in one of my pictures for the few parking spots at the airport saddle trailhead and the road to the airport overlook.
