What to See & Do
The Swim Beach at Lake Cunningham
A roped-off swimming area with a gently sloping sandy entry, lifeguard towers staffed in summer, and a floating dock about thirty yards out that kids race each other to reach. The water tends to be cooler than you'd expect for inland California, with a faint mineral smell, and on weekends you'll hear half a dozen languages being spoken on the towels around you.
Vasona Lake Shoreline
A grassy crescent on the south side of the lake where locals spread blankets under the valley oaks. You'll find ducks waddling between picnic tables, the occasional great blue heron stalking the shallows, and a paved path that loops the whole lake for walkers and joggers. The light here in late afternoon turns golden through the oak canopy, which is why you'll see so many family portraits being taken around five o'clock.
The Paddleboat and Kayak Dock
A weathered wooden pier where you can rent pedal boats, kayaks, and stand-up paddleboards by the hour. The boats have seen years of use, the paddles are scuffed. But the staff is friendly and the lake is small enough that you can't get lost. Worth doing in the first hour after opening when the water is glass-flat and you can hear fish jumping.
The Cattail Marsh Boardwalk
Tucked at the north end of Lake Cunningham, a short raised walkway threads through reeds taller than most adults. You'll catch the brackish, slightly sulfurous smell of marsh mud and, if you're patient, spot bullfrogs, dragonflies the size of hummingbirds, and the occasional river otter. It's the closest thing San Jose has to a proper wetland walk.
The Playground and Picnic Lawns
Set back from the water under shade sails and old eucalyptus, this is where most families anchor for the day. Charcoal smoke from the public grills drifts across the lawn around lunchtime, kids burn off energy on the climbing structures, and there's usually an impromptu birthday party going on at one of the reservable pavilions.
Practical Information
Opening Hours
Both Lake Cunningham Regional Park and Vasona Lake County Park are open daily from 8am to sunset, with the swim beach itself typically staffed by lifeguards from Memorial Day weekend through Labor Day, roughly 11am to 6pm on weekends and slightly shorter hours on weekdays. Outside swim season the beach is still accessible but swimming is at your own risk.
Tickets & Pricing
Entry to the parks is budget-friendly, with a modest per-vehicle day-use fee that bumps up slightly on weekends and holidays. Walk-ins and cyclists typically pay nothing. Boat rentals are mid-range by Bay Area standards, with hourly rates that feel reasonable for a couple of hours of paddling. Annual park passes are worth it if you think you'll come more than four or five times in a year.
Best Time to Visit
Weekday mornings in June or September are the sweet spot - water warm enough to swim, crowds thin, parking easy. Weekends from July to mid-August get packed, with the main lot filling by 10:30am and a steady stream of families staking out shade. Avoid the hottest July afternoons when inland temperatures push past triple digits and the lawn turns into a heat trap. Come early or wait until after 4pm when the oak shade does the work.
Suggested Duration
Plan on three to four hours for a proper visit - long enough to swim, eat lunch, rent a boat, and walk part of the lake loop. Families with younger kids easily spend a full day. If you're just stopping by for a quick swim and a walk, ninety minutes is workable.
Getting There
Things to Do Nearby
An enormous concrete skate park right next to the swim beach, with bowls deep enough to make spectators wince. Pairs well because kids who tire of swimming can wander over to watch skaters, and there's a BMX track on the same property.
Lake Cunningham hides a full water park on its far shore. Pair them for a bigger day. One parking pass covers both. The lake stays calm, the park roars. Simple.
Near Vasona Lake, a miniature steam train threads through the pines. The whistle drifts over the water every summer afternoon. Rides cost little, last minutes, thrill kids under ten. Detour here. Worth it.
A paved path links Vasona Lake north to downtown San Jose. Walk five minutes and back under riparian shade. The creek chatters beside you. Stretch stiff legs. Easy.
Ten minutes from Vasona sits Los Gatos. Leafy streets. Indie bookstores. Locals line up for post-lwim cones. Dinner and a stroll. Perfect closer.
