Fisher Cave is truly one of the park's most spectacular natural wonders. Naturalist-led tours, offered on a seasonal basis, provide an interesting adventure for park visitors. From the low, narrow streamside passages to the huge rooms filled with calcite deposits, Fisher Cave offers one outstanding cave scene after another. Inside these rooms and passages are well-preserved bear claw marks, cave wildlife and a vast array of calcite deposits ranging from intricate hellectites to massive columns 30 feet tall.
