If you order online in advance it's a little cheaper. I copied this from their website... Adult Cavern Tours from $26.75 30 SUN, DEC Adult Cavern Tours from $22.75 01 MON, DEC Adult Cavern Tours from $18.75 02 TUE, DEC Adult Cavern Tours from $17.75 03 WED, DEC Adult Cavern Tours from $17.75
Different prices for different trails, and different age groups (kids, adults, seniors,). They do offer the regular discounts. I don't think I remember any being over 20/person. I wanna say an adult was like 13.50... Ish.
