Canyon Overlook Trail is a short hike
which takes you to a fine viewpoint of lower Zion Canyon, 1000
feet (304m) below. The trail begins from across the parking area
located at the east end of the Zion-Mt. Carmel Tunnel. If you're
coming from the west (from the Zion Canyon) turn right into the
parking lot immediately after emerging from the tunnel (and of
course, if you're coming from the east, turn left into the parking
lot right before the tunnel). The trail starts from across the parking
lot. It's an easy and pleasant hike of 1 mile (1.6 km) round trip of
moderate difficulty. I remember the hike to be a lot of fun, we
passed through an overhanging cave and saw some interesting rock
formations along the way. But the true reward comes at the end of
the trail, the gorgeous view of canyon.
