The coast of Catemaco stretches 12 miles along the Gulf of Mexico from  Playa
Escondida to El Carrizal.

The most prominent feature is the estuary and lagoon Laguna Sontecomapan.

The laguna is fed by mountain streams descending from Volcano San Martin Tuxtla
and the Sierra Santa Marta. A low chain of volcanic hills separates the valley of Laguna
Catemaco from Laguna Sontecomapan.

Its surrounding wetlands, sand dunes and forests contain one of the last well
preserved growths of mangroves in the coastal region of the Gulf of Mexico.
