Best dog park I've ever been too. We were on vacation and stopped here and I'm glad we did. Lots of room to run and swim and lots of shaded areas.
As for irresponsible owners/bad dogs, we had no issues at the park. Everyone was very friendly. Stay alert, watch your dog and other dogs for signs of aggression and step in before escalation.
