The tour is only about 45 min.. About 200 steps to walk up.. It's not that bad at all.. And it's pretty cheap.. Boat ride across the lake, bus ride to the cave, tour guide, bus back, boat ride back, all for under $20 or so.. Kids are cheaper.. It's awesome.. We go a few time a year just for fun.. Great pictures and fun time.. Enjoy!!!
Not sure about exact measurements, but it will take a couple of hours to get through the tour. Overall, there are about 5 rooms that are part of the tour and the final room (the Cathedral) is the biggest.
