Located just above Ainsworth Hot Springs, Cody Caves is a labyrinth of limestone caves. With an impressive array of ancient calcite formations, the cave systems are the result of 170 million years of flowing water and dissolved rock. Like other limestone caves, Cody Caves continues to evolve and change. Some areas have collapsed, glaciers have choked the cave with silt and streams have rinsed it clear again.

Visitors can catch a glimpse of the ancient calcite formations with guided tours year-round. Tours take a couple hours and bookings must be made in advance.
