The park's landscape is defined by its undeveloped coastline and its position within the Tijuana River National Estuarine Research Reserve. The terrain is predominantly flat, featuring trails that pass through coastal salt marshes, sand dunes, and riparian habitats along the Tijuana River. This confluence of fresh and saltwater environments creates a rich biodiversity.
