How difficult would you consider the cave tour? My mother has some mobility issues (bad knees amongst other things) so we where wondering what it would rate on a scale of 1-10, 1 a walk to the car, 10 hanging by ropes and shimmying through openings?

When I went, there was a 60+ year old with us. He did just fine, and he was recovering from total knee replacement. It does have some slippery parts, and slopes and some stairs. I would rate it at a 5, possibly a 6 depending on her tolerance for mobility. The hardest part I consider were going in and out.

Agree a 5 or 6 depending of the humidity

The tour goes at a quick pace and it is not easy walking. It can be uneven, steep stairs (a lot of stairs) and can be very slippery. I would not recommend for someone with mobility issues

4. Floors can be very slippery, stairs can be steep.

I agree with Moses it's really cool and when you leave there is a family owned restaurant right there by it that's very good
