Trip Planning & Best Times to Visit

If you are choosing dates from scratch, start with May to October.

The Expedition Tour is a half-day high-exertion route through undeveloped passages, requires reservations, and is limited to visitors age 12 and older.

Hours, tickets, parking, and the drive usually matter more here than underground conditions.
Reserve ahead for weekends, holiday windows, and peak family-travel periods when advance tickets are offered.

Check the official page before you leave so tickets, operating windows, and access rules do not surprise you on arrival.

Essential Gear

This cave does not need technical caving gear, but it does reward visitors who keep the carry light and their footing stable.

Sturdy closed-toe shoes

Adventure routes, steeper stairs, and longer walking sections all feel better with shoes that stay planted.

Compact daypack

A smaller bag keeps water and a layer with you without getting in the way on stairs or tighter walkways.

Light layer

Even on a more active cave route, the underground temperature usually runs cooler than the approach.

The right move here is a lighter, tighter carry instead of overpacking.
