The 630-acre Thermalito Forebay is a day use area featuring cool, clear water from Lake Oroville and located in low rolling foothills, with scenic views of Table Mountain to the east.
North Forebay
The Thermalito Forebay North features 300 surface acres of water, a 200-yard swimming area with a sandy beach, and plenty of shade. There are men’s and women’s dressing rooms, flush toilets, a drinking fountain, and a disabled-accessible fishing pier. There are 117 tables, large and small shared BBQ grills, additional picnic sites near the Forebay Aquatic Center, and a trail that circles the lagoon.
The North Forebay is reserved exclusively for sailboats, canoes, kayaks, paddle boards, and other non-power driven boats. The gravel boat launch closes at sundown.
Dogs are prohibited on the beach and turf areas.
Two paved boat ramps are available: one with 2 lanes and one with 3 lanes.
