01
Best nearby swim spot
Oak Shores at Lake Berryessa
Lake Berryessa Shoreline Northeast Of Napa • Family-Friendly Lake Beach • Closest Classic Beach Day To Vacaville
Grassy picnic areas meet easy-entry lake shallows, making Oak Shores a go-to warm-weather escape from Vacaville.
About a 40-minute drive from Vacaville, Oak Shores offers designated swim areas, shaded picnic tables, and enough shoreline to spread out on busy weekends. The water stays relatively calm, so it works well for kids, floaties, and casual paddling rather than waves or surf. Arrive earlier on hot days, as parking lots can fill and the afternoon sun gets intense along the open shoreline.
02
Best riverfront beach
Sandy Beach Park
Rio Vista On The Sacramento River • Relaxed Riverside Beach • Closest Sandy River Beach To Vacaville
This small, sandy stretch along the Sacramento River delivers an easygoing swim-and-picnic day without heading all the way to the coast.
Sandy Beach Park sits southeast of Vacaville near Rio Vista, with a protected swimming area, campground, and a mellow vibe most weekdays. The river current can be strong beyond the swim zone, so it’s a place to pay attention to posted signs and keep younger kids close to shore. Bring chairs or a blanket—the beach is simple but genuinely sandy, and the afternoon delta breeze usually keeps things cooler than inland.
03
Best all-around coastal pick
Doran Regional Park Beach
Bodega Bay Coast • Wide, Gently Sloping Ocean Beach • Best Coastal Day Trip From Vacaville
Two miles of broad, protected shoreline make Doran a reliable choice for Vacaville locals chasing a classic ocean beach day.
Doran Beach is usually calmer than many nearby Sonoma Coast spots, with gentler waves and plenty of room to walk, fly kites, or throw a frisbee. The long stretch of sand is ideal for families and mixed groups who want tidepool peeks near the jetty as well as open sand for lounging. Pack layers—the marine layer and wind can roll in quickly compared with Vacaville’s dry heat.
04
Best for surf and dog walks
Dillon Beach
Coastal Marin North Of Point Reyes • Laid-Back Surf And Dog-Friendly Beach • Great For Surfers And Dog Owners
Dillon Beach pairs a mellow, small-town feel with a long stretch of sand popular with surfers, walkers, and off-leash dogs in designated areas.
Expect a slower, old-school beach town vibe at Dillon, where the focus is on simple pleasures: surfable waves, long shoreline walks, and sea air. It’s a bit farther from Vacaville than some options, but the wide open views and typically less crowded feel can make the drive worth it. Check local rules on dog access and tides before you go, as conditions can shift quickly along this exposed stretch of coast.
05
Best scenic coastline
Stinson Beach
Marin Coast Below Mount Tamalpais • Classic Northern California Ocean Beach • Best For Big Views And Full-Day Outings
Stinson Beach combines a broad sandy shoreline with dramatic mountain backdrops, making it a favorite full-day escape for inland visitors.
Once you wind over Mount Tam from the bay side, Stinson opens up into a sweeping curve of sand that feels a world away from Vacaville’s freeway corridors. The town has just enough cafes and snack spots to turn a beach run into a leisurely day trip without feeling overbuilt. Parking can be tight on hot weekends, so leaving early and treating the drive as part of the experience pays off.
