Crystal Cave and Sequoia National Park reopen in 2025, inviting visitors to explore breathtaking underground wonders after years of restoration.
From the ashes of wildfire and the slow, deliberate healing of nature, a subterranean jewel is reborn. After a long, four-year slumber, Crystal Cave, the cherished heart of Sequoia National Park's hidden wonders, prepares to welcome visitors once more. Its gates will swing open from May 23, 2025, to September 7, 2025, marking the triumphant return of a journey into the earth's quiet, crystalline embrace. This popular tour, a pilgrimage for many, was silenced in 2021 when the KNP Complex Fire swept through the ancient groves above. Though the flames never touched the cave's delicate formations, their aftermath—a landscape of peril and patience—demanded a prolonged closure. Now, with roads mended and hazards cleared, the path to this underground sanctuary is clear, inviting a new generation to walk its half-mile of marvels.
The Long Road Back to the Depths
The story of Crystal Cave's closure is a testament to nature's dual forces of destruction and resilience. In 2021, the KNP Complex Fire ravaged the park, consuming over 4,300 acres and 16 groves of the park's iconic giant sequoias. For three months, the entire park stood silent, a necessary pause to assess the deep scars. While the main park areas eventually reopened, Crystal Cave remained isolated. Its entrance was shadowed by a grove of massive, fire-killed trees, their potential to fall making the approach treacherous. The decision was agonizing but clear: the cave would stay closed until the threat was removed.
Hope flickered for a 2023 reopening, but nature intervened again. Torrential winter rains that year battered the sole, winding Generals Highway spur leading to the cave, rendering it impassable. The damage was so severe that the road was deemed unsafe for travel, pushing repairs and the cave's revival further into the future. The goalpost moved once more to 2024, yet the meticulous work of engineers and conservationists took longer than anticipated. Finally, in 2025, the pieces aligned—the road is restored, the hazardous trees are gone, and the guardians of the park have given their blessing. The long wait is over.
Planning Your Subterranean Pilgrimage
For those ready to answer the call of the cool, dark depths, preparation is key. The adventure is a structured, ranger-led experience designed to protect both the fragile cave ecosystem and the visitors. Here’s what you need to know before you go:
Ticketing & Logistics
-
Availability: Tours run daily from 9:00 AM to 3:00 PM during the open season.
-
Cost: Tickets are priced at $21.00 for adults and $11.00 for children under 10. Crucially, this fee is in addition to the standard Sequoia National Park entrance pass, which ranges from $20.00 to $35.00.

The Physical Journey
The Sequoia Parks Conservancy emphasizes that proper enjoyment requires "preparation." This is not a casual stroll. The experience begins with a steep, quarter-mile descent on a paved trail from the parking area just to reach the cave's mouth. Once inside, the guided tour covers another half-mile of uneven, sometimes slippery, paths and includes numerous stairs.
-
✅ Recommended for: Individuals in good physical condition who can comfortably walk and climb for approximately 50 minutes in a cool, dim environment.
-
❌ Consider postponing if: You have significant mobility issues, heart or respiratory conditions, or find sustained walking on inclines challenging.
What to Bring (and What to Leave)
-
Attire: Dress in warm, removable layers. The cave maintains a constant temperature of around 50°F (10°C), a stark contrast to the summer heat above.
-
Gear: Bring your camera! The otherworldly formations of flowstone, draperies, and helicities are unforgettable. However, be mindful of the rules:
-
Permitted: Standard still photography and videography.
-
Prohibited: Flash photography, tripods, and selfie sticks (to protect formations and ensure group safety and flow).
-
Mindset: Bring curiosity and a sense of quiet wonder. This is a place for observation and reverence.
An Experience Worth the Wait
For those who venture into its depths, Crystal Cave offers more than a geological tour; it is a journey into time and resilience. The cave's delicate formations, sculpted by droplets of water over millennia, stand in silent contrast to the fiery drama that unfolded in the forests above. They are a reminder of the slow, persistent forces that shape our world. The guided tour, led by knowledgeable park rangers, brings this hidden landscape to life, sharing stories of its discovery, its ecology, and the ongoing efforts to preserve its fragile beauty.
The reopening of Crystal Cave is more than just the return of a tourist attraction. It is a symbol of recovery, a chapter in the ongoing story of Sequoia National Park's endurance. It represents the careful, often unseen work of conservation—of clearing dangers, repairing infrastructure, and balancing public access with permanent protection. For the visitor in 2025, stepping into the cool, silent darkness of the cave will be to participate in that story. It is to witness a masterpiece that has been patiently waiting, untouched and pristine, for its audience to return. The four-year interlude has only heightened the anticipation, making the first glimpse of its glittering chambers all the more profound. This summer, the earth's hidden gallery is open once more, inviting all to marvel at the beauty wrought from patience, water, and stone.
