Park Information

HIGHLIGHTS: Harry A. Merlo State Recreation Area is adjacent to Humboldt Lagoons State Park and offers access to Big Lagoon,  the largest of Humboldt’s coastal lagoons and a popular spot for fishing, where salmon, trout and many other fish species live.

ACTIVITIES: Fishing, bird-watching, windsurfing and boating are popular here. Use of small boats up to 5 mph is permitted, which maintains a peaceful environment for wildlife and human visitors. (Note that waterfowl hunting is allowed in the fall.) Swimming is allowed in Big Lagoon. The adjacent Humboldt Lagoons State Park adds to the possibilities for hiking, beachcombing, whale-watching and camping.

VISITOR CENTER: There is no visitor center for this park. Stone Lagoon Visitor Center, part of Humboldt Lagoons State Park, is open when staffing permits.

CAMPGROUNDS: Harry A. Merlo State Recreation Area is a day-use park with no campground facilities or RV access. Nearby Stone Lagoon has six basic campsites at Ryan’s Cove, which are seasonally accessible by boat only. Dry Lagoon also has six basic hike-in campsites. Both campgrounds have pit toilets and no running water or trash disposal cans, so plan accordingly.

TRAILS: Harry A. Merlo State Recreation Area does not have trails, and is visited more frequently for its splendid kayaking, boating and fishing than for hiking; however, adjacent Humboldt Lagoons State Park contains the Big Lagoon Beach Trail, a walkable 3.5 miles of sandy shoreline (called a spit) between Big Lagoon and the Pacific Ocean. Be mindful of the tides, as in the wintertime the surf can crest the spit and wash into the lagoon. For a longer hike, you may continue south through Big Lagoon County Park and into Patrick’s Point State Park.

MUST-SEE UNIQUE FEATURE OR SEASONAL HIGHLIGHT: Roger Goddard of the District Office for North Coast Redwoods State Parks, says that Harry A. Merlo’s location, situated next to Big Lagoon, makes it unique. Roger says the park has a beautiful, almost primitive character, and the lagoon access within the landscape of old-growth groves creates a magnificent experience for kayakers, boaters and anglers.

HIDDEN GEM: Roger says that the hidden gem here is the dark sky at night; with very little ambient light, the area is highly regarded for its stargazing.

FEATURES ACCESSIBLE TO PEOPLE WITH DISABILITIES: None.

DOGS: On leash in designated parking areas.

ENTRANCE FEE: None.
