In the early 1900’s, Dry Lagoon was drained by early farmers and several types of crops were attempted but none proved economical. Today the marshland habitat has returned and supports a rich variety of marsh plants, birds and other animals.

In the early days, several dairy ranches were established along the shores of Stone Lagoon. Later, when the highway was improved, a motel/restaurant called the "Little Red Hen" was located next to the lagoon. This business continued in operation until 1979. The restaurant building was remodeled into a museum and park office and is now the Humboldt Lagoons Visitor Center and bookstore.

There are 6 environmental campsites at Stone Lagoon accessible by foot or boat only (camper must provide their own boat). The campsites are on a recently completed section of the Coastal Trail. Dry Lagoon environmental camp also has 6 campsites. Self register for Stone Lagoon boat-in camps near the boat ramp at the visitor center. Dry Lagoon camps require obtaining a combination to a locked gate, therefore registration is via the visitor center (Monday thru Friday 8:30-1:30) or by contacting Patrick’s Point State Park, 10 miles south on HWY. 101.

There are day use only picnic areas at the visitor center, Dry Lagoon and at the north end of Stone Lagoon on the beach. The park offers boating, fishing, beach combing, hiking.
