Guided tours leave every few minutes and last approximately one hour. Tours are conducted over concrete pathways through the Cave's refreshing 60 degree environment. Park interpreters will lead you and your family through room after room of incredible mineral deposits. Giant columns, delicate soda straws and massive draperies abound throughout the cave. Millions of years of struggle between water and rock have created this cavern with more onyx formations than any other known cave or cavern. In fact thousands of school children each year explore Bridal Cave as part of their educational program. A tour through Bridal Cave is a family adventure you will never forget.
