Where collection is allowed
Lost World Caverns sells self-guided cave admission and optional gem-mining bags. The operator says sluice finds may be kept; this does not authorize removing cave material.
Book or confirm current hours, prices, weather impacts, and any mobility considerations for the 120-foot descent and half-mile loop.
Tools, limits, and timing
Tools and methods
Stay on the cave trail and use no tool on natural formations. At the sluice, use only the provided screen and purchased concentrate.
Amount and use
Keep purchased sluice-bag contents only. Do not touch or remove calcite, rock, fossils, or other material from the cavern.
Season and current status
Open on a changing seasonal schedule; confirm current hours.
Rules to confirm at the site
- Remain on the cave trail.
- Touch or remove no natural formation.
- Use only purchased sluice material.
- Do not label bag contents as native to the cave.
An old webpage, saved map, app layer, social post, or prior visit cannot override a current closure, posted boundary, permit condition, mining claim, staff instruction, or landowner decision.
What makes the site geologically useful
Groundwater dissolved carbonate rock and redeposited calcite to build stalactites, stalagmites, columns, and flowstone.
Prepared gem bags are an identification activity, not evidence of the cavern’s mineral assemblage.
