Came here with my wife, her parents and aunt and uncle for a tour in her birthday. Her parents are in their early 60s, and her aunt and uncle are in their 70s. There are 444 steps one way, it's 1800 feet long, and a 110 foot change in elevation over the course of the 1800 feet, which is one way, and then you go back out the same way you come in, so 444 more steps, etc. If you have bad knees, be aware, it CAN be done, but can be very difficult. My mother-in-law has has both knees replaced and she did it, but she was very sorry the rest of the day. The cave is cold inside (a constant 40° all year long), so bring a jacket, but I ditched mine halfway through cause I was getting hot. I am 5'8", 300 lbs and our of shape, but I was able to complete it, yeah there were places I was huffing and puffing, but I did it. So for $8 if you're under 65, and $4 if you're over, and if you're looking for something cool to see for a few hours, yeah this places is pretty cool, both literally and figuratively. Our tour guide was very knowledgeable and accomodating for the elderly people in our group, and answered all of our questions. If you forget a jacket, they sell hoodies for $50 for the desperate at the entrance to the cave. Give this place a shot, the drive to the cave itself is beautiful and a great way to spend a few hours. read more
