Llico is an access point situated on the Estero Llico in the Vichuquén commune of the Maule Region. The estero and its surrounding wetland cover roughly 103 hectares and are classified as a permanent continental riverine system.

A small portion of the wetland falls within an urban boundary, and approximately four hectares carry some form of protected-area designation.

The mouth of the Estero Llico has been the subject of analysis by Chile's Ministry of Public Works, reflecting ongoing interest in the hydrological and environmental conditions at this coastal outlet.

The site sits within the province of Curicó and represents a notable natural feature along this stretch of the Maule coast.
