Comalcalco Ruins are w. on Mex. 180 to the town of Cárdenas, then n. about 35 km (22 mi.) on Mex. 187 to the town of Comalcalco; the turnoff to the site is about 3 km (2 mi.) farther n., to the right. There are no informational highway signs en route from Villahermosa; watch for signs in Comalcalco that direct visitors to the ruins.
This large site consists of several tall pyramids spread out over grassy meadows and small hills. The structures here were constructed of thin, flat bricks called tabiques, covered with a plaster made from ground seashells, rather than the stone used elsewhere in pre-Hispanic Mexico. Heed the signs warning No Subir (Do Not Climb). A small one-room museum contains carved stone figures.
Descendants of the Chontal Maya, who originally inhabited Comalcalco around A.D. 600-900, still live in the area and earn a livelihood as their ancestors did by processing cacao and raising bananas and other fruits. Note: This is one of Mexico's hottest regions; visit early in the day and bring a hat or umbrella as a sunscreen.
