Continuing our expedition through the Huasteca Potosina, we found a guide to row us against the current to observe the Tamul waterfalls. It was a pleasant ride, although when we got to the viewing rock, we had to wait for a turn, quickly take our triumphant photos, and even more quickly get back on our lancha to let the eager group of Catalan tourists have their chance.
We stopped to bathe in a mysterious cave on the way back.
While swimming we met some Chilangos who explained to us that as non residents of the capital city we can only drive into it between 10 pm and 5 am!
On our return, our vegan feast was waiting for us at Tanchachín.
We decided to drive to the Sótano de las Huahuas, an open air pit cave 60 meters in diameter and 478 meters deep. Over a million white collared swifts dive into it every evening at dusk. A lovely young lady escorted us. She instructed us on the proper etiquette for swift viewing.
We walked back up the 900 steps to the parking lot, and drove to Aquismón for the night.
