A unique natural landmark, Purgatory Chasm runs for a quarter of a mile between granite walls rising as high as 70 feet. Popular with picnickers and rock-climbers alike, the Chasm is believed to have its origin in the sudden release of dammed-up glacial meltwater near the end of the last Ice Age, approximately 14,000 years ago.

Trails lead to a wide variety of rock formations, with such romantic names as The Corn Crib, The Coffin, The Pulpit, Lovers' Leap and Fat Man's Misery.

An adventurous playground, equipped with a play structure, swings and a merry-go-round, is now located near the visitor center.

Please be aware chasm rocks and slopes are slippery and deceiving. Wear rubber soled shoes or hiking boots.  Please stay away from the edges of the chasm.  It is not recommended to hike the chasm after or during inclement weather due to extremely slippery rocks.

Well behaved dogs are welcome, but must be leashed at all times.
