Boyden Cavern, a popular visitor attraction in Giant Sequoia National Monument (Sequoia National Forest) on the floor of the Kings Canyon, is open for the season as of Wednesday, May 15. The area, which includes a souvenir and snack shop, picnic area, and restrooms, has been closed since it was damaged by the Rough Fire in the late summer of 2015.
Boyden Cavern is a cave that goes deep into the marble underground of Windy Cliffs. Its features include stalagmites, stalactites, flowstone, and unique pendant and shield formations. The parking lot is next to the South Fork of the Kings River, where Highway 180 crosses the river in the canyon bottom.
Tours are 50 minutes in duration. The cave is a constant 55 degrees, so dress appropriately.
It is a steep, uphill walk to the cave entrance, which takes about five minutes. The tour extends about 750 feet into the cave.
Now under new management, the concessioner — Windy Cliffs Inc. — has announced its 2019 tour schedule.
