When scheduling your outing, be mindful that the only restrooms they have are porta potties that are located in the large parking lot. There are a few drinking fountains located in different areas of the beach, but your best bet will be to bring your own water to keep things easy.
Be sure to bring your leash as a back up for you and your dog, only because horses are also allowed on this beach. Many visitors have said that they have seen horses around the beach so if you think your dog may get spooked, take your leash with you just to be safe about the situation.
As with any time you take your dog anywhere, make sure you pack up some waste bags. That way you can pick up your pups waste as you walk around. This is a beautiful beach so you do not want to litter it up and make it an unsatisfactory experience for others coming to visit.
