Grutas de Cacahuamilpa is a show cave in Mexico. They allowed me to photograph in the cave with the stipulation that I could not sell the photos, but could provide them for free on the internet. Photos taken by tourists who share their photos are okay, but professional photographers looking to sell photos need a permit, which I did not have.
So, I haven't sold any, nor produced any. Until now. Partly because my pics from the cave are only marginally good. I was on a normal tour, and not a photo trip. It is a fantastic cave, and would love to do a proper photo trip in there someday, but for now, here are some pics from Grutas de Cacahuamilpa.
