Zion offers a wide variety of hiking trails and opportunities, ranging from easy half-hour walks to grueling overnight hikes. Several free brochures on hiking trails are available at the visitor centers, and the Zion Natural History Association publishes several good booklets describing established trails and off-trail routes. Hikers with a fear of heights should be especially careful when choosing trails -- many include steep, dizzying drop-offs. The authors and other experienced hikers provide the ratings here, but these are entirely subjective.
Guided hiking, rock climbing, and biking trips in the area outside the park plus shuttle services are offered by several local companies, including Zion Adventure Company, 36 Lion Blvd. (P.O.

Day Hikes -- Hikers have the chance to see the park from two completely different perspectives -- a high plateau hike affords a look down into the canyons, while a descent into the canyons provides spectacular views skyward.
