The site is divided into two areas. The site core is located on a hill above the lake and with a good view across it. The second area is spread along the lake shore and the hillside leading to the site core. The site core has at least 80 structures arranged around five plazas. The majority of the structures are residential in nature but La Trinidad has an unusual amount of ceremonial architecture for such a small site. La Trinidad seems to have been an important port for the import and export of goods to and from Motul de San José.
