Even the road driving into the park is interesting...we called it the roller coaster road! This cavern was carved by a rushing underground river so the formations are different than other caves, kind of reminded me of Arizona a little bit. Beautiful grounds surrounding as well, nice hiking trails outside the caverns, so plenty to do while you wait for your tour to start. Tickets a little bit pricey. Lots of extra fees are added to the price that I was not aware of. Ended up being $90 for 5 adults and one 3 yr old., just to tour the cave. Cave tour lasts and hour and a half. Don't bother bringing a stroller, you'll end up carrying it around the terrain of the cave.
