Beach guide
Big Break Regional Shoreline
Oakley, Contra Costa County, CA
Overview
Big Break Regional Shoreline is an East Bay Regional Park District park at 69 Big Break Road in Oakley, on the edge of the San Joaquin River in the western Delta. It is a paddling and fishing park rather than a trailer launch: kayaks and canoes put in from a small sheltered beach, and anglers use a 100-foot fishing pier.
Layout
From the large, free parking lot a paved, level path leads about a quarter mile to the beach launch. Free kayak carts help with the walk. The park also has the Big Break Visitor Center (opened 2012) with a 1,200-square-foot interactive map of the Delta watershed, picnic areas, meadows and an amphitheater.
Paddling conditions
Big Break is an official San Francisco Bay Area Water Trail trailhead. Winds and currents on the San Joaquin can be strong, and cargo ships, powerboats and sailboats move along the river regularly, so the water trail rates it for paddlers with some experience. At lower tides the beach launch surface and slope become harder to use.
Wildlife and seasons
River water mixes with salty tides here, and the marshes draw more than 70 bird species. Hunting takes place in nearby wetlands from October to February. Swimming is prohibited, and the park posts blue-green algae advisories when present.
Getting there & access
Getting to the launch
Park in the free lot at 69 Big Break Road and follow the paved, level path about a quarter mile to the small sheltered launch beach. Free kayak carts are available. The beach slope can limit access at lower tides.
Hours
The park is open 5 a.m. to 10 p.m.; the vehicle gate follows seasonal hours (8 a.m. to 7 p.m. in June through September). The visitor center is open Wednesday to Sunday, 10 a.m. to 4 p.m.
On the river
Strong winds and currents are common on the San Joaquin River, and cargo ships, motorboats and sailboats use the channel. Stay out of the shipping lane, watch the wind forecast and paddle within your skill level.
Restrooms
There are restrooms in the parking lot, at the launch and in the visitor center. The launch restrooms do not have running water.

Rules & official resources
- Swimming is prohibited
- A California fishing license is required to fish from the pier or shore; no separate park permit is needed
- Keep your distance from wildlife: 650 feet from bird nesting colonies, 50 feet from Ridgway's rail habitat and 820 feet from large groups of floating waterbirds
- Carry a wearable Coast Guard-approved life jacket for each person on board
- Clean, Drain and Dry your boat, trailer and gear: inspect it, remove plants and mud, drain every compartment that holds water before leaving, and let everything dry. The Delta is confirmed infested with golden mussel, so expect inspections at other California waters
Common boat service needs here
Kayak and gear cleaning
The Delta has golden mussel, so paddle craft, paddles and gear should be cleaned, drained and dried before use on any other water, including East Bay lakes that inspect boats.
