Rosie's Dog Beach in Long Beach is the only place in Los Angeles County where your dog can legally run off-leash on ocean sand. It's 4.1 acres, it costs nothing, and it doesn't care what brand of kibble survived the latest recall. The beach sits on Ocean Boulevard between Granada Avenue and Roycroft Avenue, opens at 6 a.m., and closes at 8 p.m. every day. Outside those hours, dogs are banned from the sand entirely. Inside them, the rules are straightforward: license, leash until you reach the zone, pick up waste, and keep your dog under voice control. Violations start at $100, but the bigger cost is the heat—when air temperature hits 85°F, the sand can reach 125–140°F, hot enough to burn paw pads in under a minute.
Karpo checks live parking meter rates at Granada Avenue, confirms today's beach conditions, and maps the fastest route from your location to the off-leash zone—including which side of Ocean Boulevard has the metered spots.
The four-acre window
Rosie's Dog Beach occupies 4.1 acres of Belmont Shore sand between Granada Avenue and Roycroft Avenue along Ocean Boulevard. It opened in 2003 and remains the only legal off-leash dog beach in Los Angeles County. The space is not fenced. Two posts mark the general boundaries, but the real landmark is the colorful "Dogs at Play" sculpture near the Granada Avenue parking lot. Rangers use traffic cones to delineate the zone during busy weekends, though the cones migrate depending on tide and crowd size.
The beach opens at 6 a.m. and closes at 8 p.m. every day. Outside those hours, dogs are prohibited entirely—not just off-leash, but on the sand at all. First violation runs $100. Repeat offenses within one year escalate to $200, then $250 to $500. Rangers patrol most heavily on summer Saturdays and Sundays, making rounds every two hours starting at 7 a.m. Early-morning visits avoid both the citation risk and the heat.
Dogs must stay on leash until they reach the off-leash zone. The paved bike path called Shoreline Way runs parallel to the beach, and walking your dog along the path instead of simply crossing it counts as a violation. The distinction matters because the path is technically separate from the beach access routes. Rangers watch for dogs on the path itself, even if owners are clearly heading toward Rosie's.
Sand temperature and saltwater math
When the air temperature reaches 85°F, the sand at Rosie's can hit 125–140°F. That's hot enough to burn paw pads in under a minute. The test is simple: press your bare hand or foot against the sand for ten seconds. If you can't hold it, your dog shouldn't walk on it. The 6 a.m. opening makes early visits easy, and morning sand stays cool until around 9 a.m. in summer. By noon, the sand is often too hot for sustained play.
Saltwater toxicity is the other risk. Dogs that swallow too much ocean water while swimming or fetching can develop muscle tremors, disorientation, and seizures. Even smaller amounts cause severe diarrhea from the magnesium content. Bring fresh water and offer it between swims. If your dog is drinking seawater rather than just getting splashed, cut the session short. Early warning signs include excessive drooling, vomiting, and loss of coordination. The nearest emergency vet is Long Beach Animal Hospital on East Seventh Street, about ten minutes by car.
Licensing and liability on an open beach
Every dog at Rosie's must be licensed, vaccinated, and over four months old. Long Beach charges $20 for a spayed or neutered dog, $250 for an unaltered animal. Rangers check tags, and the $250 unaltered fee catches people off guard. If your dog isn't spayed or neutered, getting the procedure done before your visit saves more than $200 on licensing alone. Puppies under four months are prohibited for their protection and the safety of other dogs.
California is a strict-liability state for dog bites. If your dog bites someone at Rosie's, you are liable for medical costs and other damages even if your dog has never bitten before and you took reasonable precautions. The off-leash environment means dogs interact with strangers and unfamiliar animals constantly. If your dog has any history of reactivity, an open beach is a high-risk setting. Spiked collars are banned because they can injure other dogs during play.
Parking and the Granada lot
The Granada Avenue parking lot at 5000 East Ocean Boulevard is the main access point. Spaces are metered, and the lot fills by 8 a.m. on summer weekends. On weekdays and during cooler months, parking is easier through mid-morning. Additional metered parking lines Ocean Boulevard between Granada and Roycroft, but those spots turn over faster because beachgoers without dogs use them too.
Waste bags are provided in dispensers near the lot, but the city encourages bringing your own. Scoops are available. Trash cans are placed throughout the off-leash zone. Restrooms and outdoor showers are located near the Granada lot. The beach can close occasionally due to special events or poor water quality, though closures are rare and usually announced on the city's Parks, Recreation and Marine website.
Monty's and the agility course
Monty's Dog Beach & Bar sits near the Granada parking lot. It's a snack shop with an outdoor agility course and limited beach chair seating. The agility course is small but free to use—just a few jumps and tunnels on artificial turf. The seating is in high demand on busy weekends, and Monty's doesn't take reservations for the chairs. The menu is basic: hot dogs, chips, soft drinks. It's a convenience stop, not a destination, but the agility setup gives high-energy dogs something to do before or after swimming.
The rest of Belmont Shore Beach, centered on Granada Avenue, is off-limits to dogs entirely. Volleyball courts line the sand outside the off-leash zone, and the bike path continues east and west. The distinction between Rosie's and the rest of the beach is not always obvious to first-time visitors, which is why rangers issue so many citations for dogs outside the designated area.

Ask Karpo first
Ask Karpo what time the Granada Avenue parking lot fills up on Saturday mornings, whether today's ocean temperature is safe for prolonged swimming, or which Long Beach veterinary clinics near Belmont Shore offer same-day spay appointments. Karpo pulls live tide schedules, checks current beach advisories, and maps the nearest emergency vet if your dog swallows too much saltwater.
