A fantastic hiking trail along the road to the third station, which is where two rivers meet. It's worth stopping by all the viewpoints. The route is only one way, as the steepness of the road makes it somewhat difficult to walk back. You can hire a ride from the third station to the road. There is a fee to enter the site and for transportation up. You can also get there by private car; it's located about half an hour from Zacatlán, Puebla.
