The 40-acre Tri-City Park is located in the City of Placentia, is bordered on two sides by the City of Fullerton, and is within a quarter-mile of the City of Brea’s border. It includes a lake and three reservable picnic shelters. A variety of recreational opportunities, including bicycling and walking, model sailboating, fishing and playgrounds are available.  

An 8-acre lake is visited by many annual migratory waterfowl. Fishing for catfish and bluegill is allowed with a California Fish and Game License. Launching of model radio-controlled sailboats is also permitted.

The park is also a wildlife sanctuary and is very popular as a bird watching destination.

Three picnic shelters provide shade with tables and barbecues. In addition there are picnic tables and park benches scattered throughout the facility.
