The main attraction in the town. Cahal Pech is a smallish set of Mayan ruins that were abandoned around 800-900 AD. There is an indoor museum displaying artifacts, a site plan, and information on the ruins in a regional context. There are, allegedly, guided tours, but these are unneeded, as the site is easy to traverse. The entire site should take 1-2 hours at most for a thorough exploration. Once at the ruins, the site is fairly flat, but Cahal Pech is at the top of the hill overlooking San Ignacio. The walk uphill to it from the main town is quite exhausting and is difficult even from the San Ignacio Resort Hotel on the hill. If you have any disability, or are in poor physical condition, you will want to drive.
