At park headquarters the National Park Service has established an official information office and museum which is open daily throughout the main travel season. Here park visitors may secure information and free publications regarding this and other national parks. The museum exhibits cover such subjects as geology, biology, archeology, and history. The Zion-Bryce Natural History Association maintains a stock of publications, maps, and transparency slides which are for sale at reasonable prices in the museum. They are designed to assist in a better understanding and appreciation of the region.
