Fern Cave Tours
Most caves in the Monument can be explored anytime without a reservation. Fern Cave, however, is closed for resource protection reasons and is open to visitors by ranger-guided tour only. The entrance area is not open to the public at any time other than during a ranger-guided tour. The exceptional rock art and sensitive biotic environment in Fern Cave are among the reasons that only guided tours are allowed here.
The tour is offered on Saturdays at 2:00 p.m. from May 18th through October 31st, weather and road conditions permitting. Please note that there will be no tour on September 7th due to the park's participation in the Tulelake Fair.
