The park's ground is mostly made of wood chips and dirt, and there is plenty of shade and water fountains for Fido on those hot summer days. There are garbage pails and bags available, and they also have water fountains for the dogs. Before entering any dog park in Suffolk County, make sure your dog is up-to-date on his vaccinations and is spayed/neutered.
Keep your dog on-leash until you are inside the park, which has double-gated entries. Teach your dog to remain calm upon entering and make sure he is well trained. Most importantly, pick up after your dog. They also suggest not bringing your dog's favorite toy, as sharing might make your dog feel like his property is being threatened. And of course, watch your dog. Suffolk County Parks encourages putting down your phone and closely watching your dog.
To enter the park between Memorial Day and Labor Day, you'll need a GreenKey, which will give you access not only to Blydenburgh County Park but other Suffolk County Parks as well. The pass costs $30 for residents and is valid for three years and also gets you discounted rates for other parks and park amenities in the county. If you are just visiting Suffolk County, the pass will cost a non-resident $200. To get into the park, use the main entrance on the North side of Vets Highway. Once in the park, follow the signs to the dog park.
