This place is another historical landmark that is a must see with family! About a 30 min car ride…read moreout side of Monterrey mexico you arrive at a location with little food stands and ticket office, it had quite a few tourists for being mid January and it being about 60 degrees. Each ticket price per person to go up to the cave was about $4-$5 depending on the peso rate and it even included a tour guide. The little tour is about 45 min long and there is a lot of walking and stairs, and the restrooms were so clean for being out in the middle of almost nowhere! Definitely a must see!!!
