Trailhead & Parking
Drive west on Hwy-9 toward Mt. Carmel Junction. Pass through the long 1.1 mile Zion Tunnel and on to the small tunnel. Upon exiting the small tunnel drive 1.9 miles to a small pullout. The pullout only accommodates 4-5 vehicles and is the parking spot for canyoneers exploring Keyhole Canyon.
There is no trail to South Ariel Peak, the massive sandstone slab to the left is the trail.
