The Crystal Palace Tour is a 1 hour 45-minute guided route that brings visitors up close to vibrant formations in a living cave roughly 155 feet below the surface.

Highlights

Outing Highlights

THE SHOW CAVE

A full, show-cave experience

This is the full 1 hour and 45 minute tour of the entire show cave — rated among the most beautiful show caves — that extends beyond shorter options to reach the most decorated parts of the cave along the walking trail.

THE DECORATIONS

Dense, formation-rich passages

The tour leads into the cave’s most decorated portions where formations crowd the trail, often to within inches, making the route a uniquely intimate underground display.

THE ADD-ON ROUTE

More time and distance than the Horseshoe Lake option

This route adds additional time and distance to the Horseshoe Lake Tour, taking you deeper into the decorated corridors that define the Crystal Palace experience.

What the day feels like

What the tour feels like

Guides lead small groups through humid, warm corridors 155 feet below the surface, moving along a defined walking trail past dazzling crystal formations. The tour lingers in the cave’s most decorated sections, with formations so close they often overhang the path — a slow, deliberate walk through an active subterranean landscape.

Suitability

Who it's for

Who this tour suits — and who should reconsider.

1
Active Day TravelersIdeal for travelers comfortable with walking and stair descent who want an immersive, formation-rich cave experience; expect a nearly two-hour guided route with sustained walking.
2
Visitors with Mobility LimitationsNot recommended for those who cannot manage long stair descents or climbs — the tour involves about 360 steps and a 15-story elevation change.
3
Families with Older ChildrenSuitable for families whose children can handle stairs and warm, humid conditions; parents should evaluate each child’s stamina and comfort with enclosed spaces.
4
Those Sensitive to Heat or Respiratory IssuesNot a great match for travelers with heat sensitivity or certain respiratory conditions due to high humidity, warm temperatures that feel like ~85°F, and slightly lower oxygen levels.
