Grutas de Cacahuamilpa

The Cacahuamilpa Caves (Grutas de Cacahuamilpa) form one of the largest cave systems in the world, with vast chambers full of stalactites and stalagmites. They are protected as a national park in northern Guerrero, near the silver town of Taxco and very close to the border with Morelos, which is why the two states are easy to confuse.
