The short answer
Long Beach's beaches are unusually calm because the federal breakwater and Alamitos Bay knock the surf flat, which makes them some of the most kid-friendly, swimmable sand in Southern California. Rosie's Dog Beach is LA County's only leash-free dog beach, Mother's Beach is the go-to for little kids, and Alamitos Bay spots like Bay Shore stay glassy year-round. Note for 2026: the old Belmont Plaza pool is gone, with its $105M replacement under construction through 2028.
Here's the Long Beach secret that confuses first-timers expecting big Pacific waves: the water barely moves. The offshore federal breakwater and the tucked-in geography of Alamitos Bay flatten the surf into something closer to a lake, which is exactly why parents, paddleboarders, and nervous swimmers love it here. What Long Beach lacks in barrels it makes up for in warm, wade-in-forever shallows and wide, easy sand.
We verified all nine of our picks for 2026, checked parking and access, and added one blustery outlier for the kite-and-windsurf crowd. A few things have changed since our last pass - most notably the demolished Belmont Plaza pool - so read the 'Good to know' lines before you load up the car.

01Alamitos Beach
Downtown / East Village
Calm waterFamily-friendlyWalkable from downtownMetered parking
The westernmost link in Long Beach's beach chain, Alamitos runs from downtown out toward Alamitos Bay on a wide, soft, wide-open apron of sand. Shielded by the Port of Long Beach and the offshore breakwater, the water stays gentle enough for skimboarding rather than surfing. There's an aquatic playground, free volleyball courts, and a concession stand that rents everything from beach cruisers to umbrellas.
Good to knowADA beach-access mobility mats run to the water, and metered lots sit right behind the sand plus overflow at Marina Green.
02Rosie's Dog Beach
Belmont Shore
Off-leash dogsOnly one in LA CountyFamily-friendlyMetered parking
This is the headliner: Rosie's is the only leash-free, off-leash dog beach in all of Los Angeles County, a roughly three-acre stretch of sand where good dogs run straight into gentle surf. It sits along Ocean Boulevard in Belmont Shore between Roycroft and Argonne Avenues, with a metered lot right there. Expect a happy, sandy, tail-wagging crowd on any warm weekend.
Good to knowDogs run leash-free only inside the marked zone; bring waste bags and check current city rules before you go.
03Mother's Beach
Naples / Marine Park
Toddler-friendlyVery calm waterPlaygroundLot parking
Tucked inside Alamitos Bay just below Marine Stadium on Naples Island, Marine Park - everyone calls it Mother's Beach - is the definitive Long Beach spot for little kids. It's protected from open-ocean waves, so the designated swim areas stay consistently calm and shallow, and a modern playground sits right at the sand's edge for easy supervision. Dragon-boat and outrigger clubs launch from here, and there's a weekend cafe.
Good to knowA dedicated lot serves the beach and a grassy picnic ring circles it - ideal for a stroller-and-cooler day.
04Bay Shore
Alamitos Bay / Peninsula
Calm year-roundSwimmersWatersportsRestrooms + showers
On the southwestern shore of Alamitos Bay near the Belmont Shore, Naples, and Peninsula neighborhoods, Bay Shore is separated from the open ocean by the Alamitos Peninsula - which keeps the water tranquil year-round. There's a designated swim area, a 500-yard open-water course for stronger swimmers, plus basketball and handball courts and a playground. In summer, adjacent Bay Shore Avenue turns into a car-free promenade for bikes and skaters.
Good to knowRestrooms and rinse showers sit at both ends; kayak rentals, gondola rides, and a sailing center are steps away.
05Belmont Shore
Second Street
Wide sandSocial sceneVolleyballMetered parking
The big, sociable Long Beach beach: a wide sandy stretch just south of the Second Street shopping-and-dining strip, so you can eat, shop, and swim in one loop. The breakwater keeps waves modest, making it more of a lay-out-and-play beach than a surf break, with volleyball nets and plenty of room to spread out. Parking is metered and gets tight on summer weekends, so arrive early.
Good to knowCome for the beach, stay for Second Street - one of the easiest walk-to-food beach days in the city.
06Colorado Lagoon
Bluff Heights / Marine Park
Warm shallow waterFamily-friendlyRestored tidal lagoonLot parking
This tidal lagoon near Marine Stadium is a warm, shallow, protected swimming hole that feels worlds away from the open coast - great for young families. A years-long restoration is reconnecting it to Alamitos Bay via a new open channel to keep the water healthy and flushing; the lagoon has stayed open for swimming through the work. It's one of the quieter, greener beach options in Long Beach.
Good to knowOpen-channel construction is ongoing in 2026 with some roadwork nearby; check the city's water-quality monitoring before swimming.
07Junipero / Cherry Beach
Bluff Park / Bixby Park
Bluff viewsBike pathYogaMetered lot + free street
A scenic stretch running from Junipero Avenue east to the Belmont Veterans Memorial Pier, backed by grassy Bluff Park and Bixby Park up on the bluff. It's a favorite for fitness days - free yoga in Bixby Park, outdoor exercise equipment, and the beach-level bike path - plus Alfredo's Beach Shack for food and bike rentals. The harbor-and-shoreline vistas from the bluff pathways are among the best in the city.
Good to knowFree street parking plus a metered beach-level lot off Junipero Avenue give you two ways in.
08Peninsula Beach
The Peninsula
Two-sided sandSurf or calmQuieter crowdsStreet + lot parking
The Peninsula is a skinny finger of land with beach on both sides: open-ocean sand on the south for actual small surf, and calm Alamitos Bay sand on the north for wade-in swimming. That split personality, plus its tucked-away residential setting, makes it one of the more low-key spots to claim a wide patch of sand. It's a walk-and-explore beach more than an amenity-heavy one.
Good to knowPick your side by mood - ocean for waves and sunsets, bayside for glassy, kid-safe water.
09Belmont Plaza (beach)
Belmont Shore
Open sandNear the pierPool closed until 2028Metered parking
The sand here is still open and swimmable, but the landmark it was named for is gone: the Belmont Plaza Olympic pool was demolished, and its $105M replacement, the Belmont Beach & Aquatics Center, is under construction through spring 2028. Until then, this is essentially a quieter extension of the Belmont Shore beachfront near the Veterans Memorial Pier. Come for the sand, not the pool.
Good to knowThe new Olympic-size aquatics center is a construction site in 2026 - budget around fencing and detours.
10Granada Beach
Belmont Heights
KitesurfingWindsurfingLaunch rampWide open sandMetered lot
New to our 2026 list: Granada is the wind-sports beach, a wide sandy expanse off Granada Avenue with a boat launch ramp that draws kiteboarders, windsurfers, and small-craft crowds. It's more open and breezy than the sheltered bay beaches, which is precisely the point when the afternoon wind fills in. It also hosts city events and festivals through the season.
Good to knowIt's an active launch area - keep kids clear of the ramp and kite lines, and use the metered beach lot.
Frequently asked
Which Long Beach beach is best for kids?
Mother's Beach (Marine Park) in Naples is the top pick - it sits inside Alamitos Bay with consistently calm, shallow swim areas and a playground right at the sand. Colorado Lagoon is a great warm, shallow runner-up.
Can you bring dogs to the beach in Long Beach?
Yes - Rosie's Dog Beach in Belmont Shore is the only leash-free, off-leash dog beach in all of Los Angeles County. Dogs run free inside the marked zone; most other Long Beach beaches restrict or prohibit dogs, so check posted rules elsewhere.
Are Long Beach beaches good for swimming?
Very. The offshore federal breakwater and the sheltered geography of Alamitos Bay keep the water unusually calm and flat, making spots like Bay Shore, Mother's Beach, and Alamitos Beach some of the most swimmable, wade-in sand in Southern California.
Is there parking at Long Beach beaches?
Yes, though most is metered. Alamitos, Belmont Shore, Junipero/Cherry, and Granada all have metered beach lots (Junipero adds free street parking), and Mother's Beach and Bay Shore have dedicated lots. Summer weekends fill up early, so arrive before mid-morning.
What happened to the Belmont Plaza pool?
It was demolished, and its $105 million replacement - the Belmont Beach & Aquatics Center, with a 50-meter Olympic pool - is under construction and expected to finish around spring 2028. The beach sand there stays open, but the pool itself is a construction site through 2026.
Can you surf in Long Beach?
Not really - the breakwater flattens the waves, so Long Beach is better known for calm-water swimming, paddleboarding, and skimboarding. For actual wind sports, head to Granada Beach; for small ocean waves, try the ocean side of Peninsula Beach.
