After Grutas de Cacahuamilpa opened for visitors, careless tourists damaged the glittering walls of the caves, which lost their sheen due to the natural oils on the hands of those who touched them. Now, the caves are a preserved area and are currently being protected by Mexico’s National Government. That is why all visits to the caves are exclusively conducted with a guide and tourists are being asked not to interact with animals and plants.

From here, you’re gonna enter the cave into the first salon, which is also the smallest one. The guide will start by giving the group some basic information about Grutas de Cacahuamilpa and as the tour continues he will occasionally stop and illuminate with his flashlight some of the cave’s most interesting formations and tell some jokes in Spanish. Most people find this very funny for the first several formations, but the tour is slow and repetitive, so everyone’s easily getting bored. You won’t get bored by the stalactites and stalagmites tho; they are in so many different forms and different in sizes, you’ll gasp at every new sight.

As you continue to explore the cave, you’ll end up at the Auditorium, which is one of the Grutas de Cacahuamilpa’s most unique salons. It is unique because this salon is used throughout the year for concerts of all types, but most commonly symphonic orchestras performances.

The tour also passes through the largest cave salon, which is about 80 meters tall, and an hour and a half, two hours later you’ll reach the final salon. Here, you’re gonna say goodbye to your guide and be left alone for the walk back. No one’s rushing you out of the cave, so this is the point at which you can really take your time and go at your own pace.

Getting back is very easy and straightforward, so don’t worry about getting lost inside the cave. If you decide that you don’t want to see more of the cave, the walk back to the surface will take you around 20-30 minutes.
