Huntington Beach State Park is a dog friendly park all year round. Dogs are welcome on the southern end of the beach and on some walking trails, however must be kept on a leash that is no longer than 2 meters.
The campground is also dog-friendly, however pets are not allowed inside any of the accommodation options and must remain leashed. There are tent sites as well as caravan/RV sites with access to power and water, all close to toilets and showers.
