Take your pup to the beach and enjoy the day with your furry best friend. Although most of the OC is dog-friendly, Huntington Beach has the best dog beach of all. Huntington Dog Beach is located between Seapoint Street and 21st Street and is the only off-leash beach in Orange County. Newport Beach and Laguna Beach allow dogs on most of their beaches (with a few exceptions) with a few rules. Dogs are not allowed on the beach between 9 am to 6 pm from June 15th through September 10th, but all other times and months they are allowed if on a leash.
