I got up shortly after 6, and had breakfast at the bus station. I packed my stuff and stored it in the hotel office. I walked the 2 kilometers to the ruins in under 20 minutes, arriving 10 minutes before it opened.

 I got in right away and grabbed a few shots of El Castillo before climbing it for a good view of the site. While more extensive than other sites, it isn’t that impressive aesthetically, but quite an achievement when size and scientific knowledge are considered. I wandered all around and took some pix, finishing close to noon.
