A long time ago this was a stone wall - today it's an arch and stands alone looking over a canyon.
You can drive to the parking lot which is approx. 25 km away from the entrance and then you have to take the 30-60 min walk to the arch.
A good sun protection and enough water is a msut during the summer months.
The Delicate arch has a diameter of ca. 12 m (40 ft) and a height of 16 m (52 ft). Best time for pictures is the late afternoon.
