Water quality & family beach guide near Līhuʻe
📍 Hanamaulu, Kauaʻi — Local park with pavilions & camping
Hanamaulu Beach Park has moderate water quality. The Hanamaulu Stream drains agricultural and residential land and empties into the bay, creating elevated bacteria risk after rain. During extended dry periods, the water is generally acceptable. The DOH monitors this beach and issues advisories periodically â more frequently than south shore beaches due to Kauaʻi's higher rainfall.
Based on: Hanamaulu Stream discharge, DOH monitoring history, Kauai east-side rainfall patterns
Hanamaulu Stream drains into the south end of the bay. After any significant rain, wait at least 72 hours before swimming. If the water near the stream mouth looks brown or murky, stay out â use the park's picnic facilities instead and enjoy the beautiful bay from shore.
County camping permitted with advance reservation. Pavilions, BBQ grills, restrooms on-site.
Covered pavilions, restrooms, outdoor showers, parking lot, and grassy picnic area.
