Lake Berryessa Access provides multiple public entry points for paddling and boating around Napa County's largest reservoir, including free day-use areas at Oak Shores and Smittle Creek with parking and facilities, plus several hand-launch spots for kayaks and canoes.

The lake offers both motorized and non-motorized boating zones, with concession areas providing full-service marinas, boat ramps, and rentals at Markley Cove and Pleasure Cove.

Visitors should note that all watercraft must pass invasive mussel inspections, and paddlers can access ranger-led guided tours during spring, summer, and fall.
