Crystal Ice Cave contains some of the most spectacular ice formations among Lava Beds many caves. Because of the sensitive nature of this cave's formations and air flow, it is open to park visitors on small ranger-guided tours only during winter months.
3.5-hour tours of six visitors each are offered every Saturday at 1:00 p.m. from December through March. This is a strenous excursion for people 12 years and older in good physical condition. Cavers ascend a sloped ice floor with the aid of a fixed rope, crawl through holes, and negotiate boulder-strewn floors while avoiding fragile formations. Helmets, gloves, sturdy shoes, and layered clothing are required. Headlamps and kneepads are highly recommended.
Each tour can be reserved up to three weeks in advance by calling the Visitor Center at 530-667-8113 between the hours of 8:30 a.m. and 5:00 p.m. This is an adventure you won't soon forget!
