A number of nationally recognized companies offer tours that include the Zion and Bryce Canyon National Parks areas, although they don't necessarily go within the park boundaries. In most cases, all you do is pay and then the outfitters arrange everything, including lodging, meals, and transportation. Offerings range from fairly standard bus tours to luxury adventure vacations where you spend your days hiking or biking and your evenings being pampered with gourmet meals, hot tubs, and first-class hotels. You'll want to contact tour operators as far in advance as possible, since reservations are required and group sizes are limited. The adventure tour operators generally specialize in small groups and have trips for various levels of ability and physical fitness. Trips are offered in a range of price categories, from basic to luxurious, and are of varying lengths.
