Visitors will cross the cave during 50 -minute guided group visits, will inspect mineral training and hearing about the history of the cave and rare geology. The rangers describe the trail – half a stiff thousand to reach the cave, then a half -one -one loop inside – like “intense”, with possible meetings with poisoned oak, bees, bell snakes and falling rocks. It is not suitable for young children or anyone with claustrophobia, say the rangers, and the stairs are about as large as a 20 -storey building.
The cave is one of the 275 known caves in Sequoia and the neighboring National Park of Kings Canyon. The only cave accessible to the park public, it has been open to visitors since the 1940s, making it one of the most visited underground monuments in California.
Savannah Boiano, executive director of Sequoia Parks Conservancy, said that many trees died near the cave in the drought of the 2010s, then ignited in the fire of the 2021 KNP complex, forcing the closure of the cave. Then come the winter storms in 2023, still damaging the road from 6 miles to the cave. To prepare for the reopening, Boiano said that the crews removed dangerous dead trees, repaired roads and replaced the solar energy system of the cave.
“It's really the epicenter of certain natural disasters,” said Boiano.
Crystal Cave includes more than 3 miles of passages interviewed, sculpted by water over about a million years. Its temperature is 50 stable degrees. Its walls are in marble – not the granite which dominates the Sierra Nevada range – and an underground stream extends next to a large part of the cave path. The last and the largest “room” is known as Marble Hall.

Visitors will cross complex passages.
