The best thing about Gifford Canyon is its a beautiful canyon in Zion that you will have to yourself! A friend, Bo Beck, talked about Gifford Canyon often so I wanted to go and see it. It's certainly a place that I will go to again. Thanks Bo!
Do not get on the Zion shuttle for this hike. Gifford Canyon is the starting point for the strenuous and technical trail to Bridge Mountain. While Bridge Mountain is not on the to do list for the average hiker, Gifford Canyon can be. The hike begins at the parking lot across the highway from the Canyon Overlook Trail. Make your way down the steep dirt path of use near the restrooms. Walk up stream for about 75 ft and climb the 15 ft. dry wash. At the top of the climb the trail is obvious. Just follow it as it winds around the mountain. It will widen once you are in Gifford Canyon. Hike up the sandy path to the end of the canyon. There are some nice views of various monoliths on the side of the trail and at the trails start and end. The trail is 3 miles round trip and takes about 2 hours to complete.
Note: check the weather report before hiking this canyon. There is a danger of flash floods.
