It’s a great Tour for young & old First-timers!! Lots of Formations & “Rooms”, nicely lit to see the Beauty of Spelunking. Pathways were easy for the Grandkids & Grandpa. They offer other more Adventurous Tours & our Guide was just great !!

The four of took the basic tour and it was interesting with not a lot of sweat. It was about a mile walk, great guide. One of those must do if you haven't been yet.
