The 630-acre Thermalito Forebay is a popular day-use area featuring cool, clear water from Lake Oroville, low rolling foothills, and scenic views of Table Mountain to the east.
Divided into distinct North and South recreation areas, the Forebay accommodates both peaceful paddling and motorized powerboating.
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. The area is reserved exclusively for sailboats, canoes, kayaks, paddleboards, and other non-power-driven watercraft, with a trail that completely circles the lagoon.
For visitors who don’t have their own watercraft, the Forebay Aquatic Center sits right on the shoreline and offers seasonal on-site rentals. Visitors can rent tandem and single kayaks, stand-up paddleboards, hydro-bikes, pedal boats, and canoes by the hour, making it easy to get out on the water without hauling heavy gear.
Key amenities at the North Forebay include:
- Boating Access: One gravel launch and two paved boat ramps (one two-lane and one three-lane) for non-motorized watercraft. All launches close at sundown.
- Picnic Facilities: 117 tables, large and small shared BBQ grills, and additional picnic sites near the Aquatic Center.
- Park Conveniences: Men’s and women’s dressing rooms, flush toilets, and a drinking fountain.
