Introducing Parque Nacional Grutas de Cacahuamilpa
One of central Mexico’s most stunning natural sights, the Cacahuamilpa caverns is a must-see for anyone visiting Taxco or Cuernavaca. The scale of the caves is hard to imagine, with vast chambers up to 82m high leading 1.2km beneath the mountainside, inside of which are mind-blowing stalactites and stalagmites.
Unfortunately, individual access to the (perfectly safe) pathway through the caves is not allowed. Instead, visitors are allocated free guides who lead large group tours (departures each hour on the hour), with constant stops to point out shapes (Santa Claus, a kneeling child, a gorilla) in the rock. At the end of the one-hour tour, you can wander back to the entrance – with the lights now off – at your own pace. Most guides do not speak English.
From the cave exit it’s possible to follow a steep path 15 minutes to the fast-flowing Río Dos Bocas. There are spectacular views year-round and tranquil pools for swimming during the dry season. Bring bug spray.
Weekends are often very crowded, with long lines and large group tours – making mid-week a more pleasant time for a visit. There are restaurants, snacks and souvenir shops near the entrance. Between the entrance and the caves, it's possible to take a short zipline (M$70) across the treetops, or you can just walk the 150 metres around. The last ticket for the caverns is sold at 5pm.
