The park and its restored wetland lie immediately east of Vulcan Avenue (a short distance east of Coast Highway 101).
The benefit of water filtration by plants (such as bulrushes and sedges) and plant litter (decomposing vegetation) is explained. Water that eventually flows into the ocean at Moonlight Beach is naturally cleaned of contaminants like heavy metals, nitrates and phosphorus.
