Pickle Springs has been designated a Natural Landmark by the National Park Service for its biological and geological values as an undisturbed site. A two-mile trail named the ‘Trail Through Time’ winds through the park and guides the visitor through 500 million year old geologic wonders carved in sandstone. The trail features clear streams, cool canyons, spectacular bluff views and ‘The Slot’, a crevice marked with holes, pockets and ridges. Visitors must climb through the ‘Keyhole’ to descend to the creek below. Twin foot bridges cross Bone Creek and pass Mossy Falls. The park is a primitive natural area and does not have services. Be sure to bring a camera and plenty of liquids before hiking the trail.
