Best beaches near Apple Valley, CA in fall for toddlers

Silverwood Lake State Recreation Area

The closest place to Apple Valley with an actual swimming beach, about half an hour up Highway 138 in the San Bernardino National Forest. It is a State Water Project reservoir with two sandy swim beaches, and the park keeps shorter hours rather than closing for winter, so a fall afternoon on the sand is realistic even after the lifeguards go home. The catch is water quality: the Department of Water Resources tests weekly for harmful algae and posts a separate advisory per beach, and Cleghorn Beach has been carrying a warning, so read the park's advisory page the morning you drive up. Dogs are not allowed on the beach or in the water.

Lake Gregory Regional Park

A mountain lake in Crestline, run for San Bernardino County by the Lake Gregory Recreation Company, with a roped swim beach, a splash pad and an inflatable water park on the water. It is the closest lake to Apple Valley that is built specifically around small children, and passes are sold per person rather than per car, with under-threes free. Everything on the water is a summer operation: the beach runs Memorial Day through Labor Day and the swim beaches themselves only from mid-June, so a fall visit means the trails, the dog park, fishing and non-powered boating instead.

Swim Beach at Meadow Park, Big Bear Lake

Big Bear Lake's only stretch of shoreline designed and staffed for swimming, tucked inside Meadow Park on the south shore with a sandy beach, a snack bar and lifeguards on duty during open hours. Admission is per person with under-threes free, which makes it a cheap, well-supervised first lake swim at 6,700 feet. It is also strictly a summer operation, open Friday through Sunday only in its last season and already closed for the year, so treat it as a plan for next June rather than a fall option.

Lake Perris State Recreation Area

A big reservoir south of Riverside with a long sandy shoreline and designated swim areas, and the only lake here besides Silverwood that stays open through the winter on a shorter schedule. The drive from Apple Valley is longer than the mountain lakes but it is nearly all freeway, and the shallow beach at Sail Cove is wide and flat enough for a toddler to potter around in. Swimming outside the staffed season is at your own risk, and dogs are kept off the sand and out of the water because the lake is a municipal drinking-water source.

Frank G. Bonelli Regional Park

An 1,800-acre Los Angeles County park in San Dimas wrapped around Puddingstone Reservoir, with a designated sand swim beach, children's play areas and shaded group picnic shelters. The park itself runs Wednesday through Sunday all year, which makes it a reasonable fall afternoon even when nobody is getting in the water. The swim beach is the summer-only part, staffed Memorial Day to Labor Day and on days the county chooses, so call the park before you count on swimming in September.

Baby Beach, Dana Point Harbor

The best water in this table for a toddler: a shallow, waveless strip inside Dana Point Harbor, roped off from boat traffic and warm by mid-afternoon. Parking is free and the lots and grass sit a few yards from the sand, which matters when you are carrying a cooler and a child at once. Lifeguards only work it in summer, and it is a working harbor rather than a postcard, so do not expect clear water or white sand. The lots fill early on weekends and there is a designated launch area at the south end where kayaks and paddleboards go in, so keep the blanket clear of the cones.

Marina "Mother's" Beach, Marina del Rey

A man-made beach on the inside of Marina del Rey with no surf at all, a children's playground a few steps from the water, and picnic tables, barbecues, showers and restrooms along the sand. Los Angeles County finished a renovation here in July 2026 that rebuilt and expanded the restroom building, added picnic shelters and a promenade, and laid a beach access mat, so it is in better shape than it has been in years. Lifeguards work daylight hours and there are restaurants within walking distance. It is a long drive from Apple Valley for a beach with no waves, so it earns the trip mainly if you are already headed to the Westside.

Mother's Beach at Marine Park, Long Beach

Long Beach's family beach, on the north eastern side of Naples Island just below Marine Stadium, where sitting inside Alamitos Bay takes the ocean motion out of the water entirely. The playground is at the north end within sight of the sand, so one adult can watch the swings and the shallows at the same time, and a big grassy picnic area with shade trees rings the parking lot. Lifeguards cover it during peak periods rather than all year. Mom's Beach House Cafe on the pier is open weekends if the picnic plan falls through.

Cabrillo Beach, San Pedro

Two beaches on one point at the mouth of Los Angeles Harbor: the inner beach sits behind the breakwater and is the calm one, while the outer beach faces open ocean a few yards away and draws surfers. The inner side has a roped-off swim area, a children's play area, a fishing pier and the Cabrillo Marine Aquarium right behind the sand, which gives you somewhere to take a toddler who is done with the water. It keeps long hours, from before dawn until late at night, and dogs are not allowed on the beach.

Corona del Mar State Beach

Big Corona is a half-mile of sand tucked behind cliffs and the rock jetty that forms the east entrance to Newport Harbor, and the jetty end is calm enough for small children to wade while the open stretch draws surfers and divers. It is a real ocean beach with fire rings, volleyball nets, restrooms and outdoor showers, open the same hours seven days a week all year. Parking is the sore point: the city runs the lot on an hourly meter with a high daily cap, it does not accept the state parks annual day use pass, and the October to April weekday rate is roughly a third of the summer one, which is a real argument for going in fall.

Doheny State Beach

California's first state beach, and the most forgiving open-ocean beach on this list for young children, because the well-known surf break sits at the north end of the park and the swimming and picnic lawn are well south of it. State Parks lifeguards patrol year-round even though the towers are only staffed from about Memorial Day to Labor Day, and behind the sand there is a visitor center with tidepool and ocean tanks, a paved beachfront path and a campground. It is one of the few beaches here genuinely set up for an off-season weekday visit.
