More ways to explore the area's outdoor wonders
The first step is a soft thud as your boot meets the cave lip, then the light contracts until the beam of your headlamp becomes everything. You duck past a low band of rock and the sound of an underground creek tightens into focus — pockets of water prickle against your knees, and a column of calcite glows pale in your light. For the next five to six hours you move on hands and feet through passages few visitors see: rimstone pools that cradle mirror-smooth water, narrow squeezes that quiz your patience, and a buried waterfall that throws a steady, cold mist.
