Jungle-shrouded Yaxchilán has a terrific setting above a horseshoe loop in the Río Usumacinta. The location gave it control over river commerce, and along with a series of successful alliances and conquests, Yaxchilán was one of the most important Classic Maya cities in the Usumacinta region. Archaeologically, Yaxchilán is famed for its ornamented facades and roofcombs, and its impressive stone lintels carved with conquest and ceremonial scenes. A flashlight is helpful for exploring parts of the site.
Howler monkeys (saraguates) inhabit the tall trees here, and are an evocative highlight. You’ll almost certainly hear their visceral roars, and you stand a good chance of seeing some. Spider monkeys, and occasionally red macaws, can also be spotted here at times.
