Oaxaca and San Sebastian de las Grutas

With the night bus, I reach Oaxaca. This is another place that is very charming at first sight. The city center around the central square is colorful, vendors offer their goods, musicians play, and artists display their works on the streets.

The next day, I join a tour to the caves of San Sebastian. With a guide, our group descends into a cave. We go deeper and deeper until we come across an underground river. We follow it for a while until we finally emerge back into daylight.
