01
Best overall pick
Seal Beach Main Beach
Old Town Seal Beach Waterfront • Classic Small-Town Pier Beach • Closest Oceanfront To Los Alamitos
A laid-back, walkable pier beach with a true small-town feel just a short hop from Los Alamitos.
If you want the quickest route from Los Alamitos to open ocean, this is where you go. The broad, sandy beach sits beside the wooden Seal Beach Pier and a compact Main Street lined with cafes and bars, making it easy to pair a swim with a casual meal. Surf can be punchy near the pier, but there is plenty of room to spread out and watch the waves if you prefer to stay on the sand.
02
Best Long Beach option
Alamitos Beach
Downtown Long Beach Shoreline • Urban Boardwalk-Style Beach • Best For Long Walks And Bike Rides
A wide, city-backed stretch of sand with a paved path that runs for miles along the Long Beach waterfront.
Alamitos Beach offers a big-sky, open feel with a long shoreline and ample space to claim a spot, even on busier days. The paved beach path is ideal for bike rides, jogs, and sunset walks, with views of the Queen Mary and harbor in the distance. It is more about mellow water and people-watching than strong surf, making it a low-key choice for groups with mixed interests.
03
Top choice for families
Mother's Beach (Marine Park)
Alamitos Bay, Long Beach • Protected Family Bay Beach • Best For Young Kids And Relaxed Picnics
A calm, sheltered bay beach with shallow water and a playground that makes days with kids much easier.
Tucked into Alamitos Bay, Mother's Beach trades surf for gentle, pool-like water and a sandy shoreline that feels made for toddlers and cautious swimmers. Shade trees, grassy areas, and nearby picnic tables give parents room to spread out while kids rotate between the playground and the water. It is a straightforward, low-stress option when you want the beach experience without worrying about big waves.
04
Go-to dog beach
Rosie's Dog Beach
Belmont Shore Coast • Dog-Friendly Open Beach • Best For Dog Owners
An off-leash stretch of sand where dogs can run, dig, and splash legally right along the Long Beach shoreline.
Rosie's Dog Beach is the rare spot where your dog gets to enjoy the beach as much as you do. The designated off-leash zone is broad and sandy, with enough width that energetic pups can sprint or chase balls without feeling cramped. Bring water and towels, and plan on lingering; the mix of ocean air, playful dogs, and late-afternoon light can easily turn a quick outing into a full beach session.
05
Classic road-trip stop
Bolsa Chica State Beach
North Huntington Beach Coast • Wide State Park Surf Beach • Best For Bonfires And Surf Practice
A long, spacious state beach with steady waves, fire rings, and a coastal bike path stretching toward Huntington Beach.
A bit farther than Seal Beach but still an easy drive from Los Alamitos, Bolsa Chica rewards the extra mileage with huge sand expanses and a more natural, open-coast feel. Fire rings dot the beach, making it a favorite for classic Southern California bonfire nights after a day of surfing or bodyboarding. The bike path and nearby wetlands also give you options if you want to mix in a ride or a quick nature walk.
