I find that Zion National Park is the most challenging place to photograph among all canyon locations I visited during my travel photography driving trip through Arizona, Utah, Nevada, California.
Let me explain. Zion was my last canyon stop before driving to deserts of Nevada. At that point I was use to hike or drive at the top rims of the canyons with the plane view in front and below me. It was always easy to find something interesting to photograph with the multiple options for good compositions.
Zion is different. It is very narrow and you drive at the bottom of the canyon and in most of the cases you have to shoot up. What I realized is that even with my widest 10mm lens it was not wide enough to fit everything I wanted to include in my composition plus the tall trees were always in my way. The only solution was to hike up to observation point to get a better view.
The featured photo is from Canyon Overlook Trail. I find this location is the most accessible (20min short and easy hike) with the observation point at the edge of a cliff with breathtaking view of lower Zion Canyon.
