Great guide, cool cave, interesting educational experience! My cousin (8 years old) especially loved it! The guide, who seemed a bit stiff at first blush) was fantastic with children and kept my cousin interested & engaged for the whole tour.
You must wait for a guided tour - you can't wander around on your own. In the off-season there's one on the hour every hour, so time your arrival appropriately or you'll end up sitting around for 45 minutes like us! But there are things to look at & read to pass some of the time. And the advantage of going in the off-season? Instead of doing the tour with a huge group, the 3 of us got a private tour. Much nicer!!
Be prepared to get a bit of a workout - there are about 500 steps down & another 500 +/- back up (though the exit is a few yards down the road so I'm not sure if its around the same number of steps or not), so it's a good way to work your legs a bit.
Overall, a nice way to spend an afternoon! read more
