About Us

Tijuana Slough is a 1,072-acre wetland located where the Tijuana River meets the sea. The refuge was established in 1980 and is part of the 2,800-acre Tijuana River National Estuarine Research Reserve (TRNERR), one of only 30 such reserves in the United States.

This Refuge is also designated as a Wetland of International Importance by the Ramsar Wetlands Convention. The National Oceanic and Atmospheric Administration (NOAA) administers the reserve system and supports research and education activities along with our partners at California State Parks and the Southwest Wetlands Interpretive Association (SWIA).
