Yes.

Not a good ideas

I travel often and, honestly, I've never heard of a campground banning dogs. Leash laws apply, etiquette requires picking up dog poop, and common decency applies concerning noise, whether it's your dog barking or loud music or an ear-splitting construction-site generator. There are too many campers who travel with their pets.

We’ve been there several times with our lab. You are not allowed to bring the dog to the beach, however there is a dog friendly beach a couple miles from the campground.

Yes. Dogs are allowed in the campground but not on the beach. There is a dog park on the beach just before entering the National Park if you want to take your pup for a swim!

Although we don’t have a dog, I did see people walking their dogs.
