This drive goes to Lava Point, the trailhead for the West Rim Trail. These photos are from an area approx 10 miles south of Lava Point. It is a good attraction after a day of hiking, and offers unusual views of the Zion bluffs from a higher elevation.

Northgate Peaks Trail
The trailhead is just off the highway. This is an incredibly easy hike, nothing to it, it ends at the edge of an ancient Lava flow. Not worth the time it takes to drive to the location unless you are just looking for a short, easy hike, or you just happen to be there.
