Your rating on this park will depend on one single factor: whether or not you want your dog to swim. If your dog(s) is a swimmer, go elsewhere, because the water here is pretty disgusting and full of algae. You don't want your dog drinking this stuff.
Other than that, it's a very pretty park, very quiet, very undeveloped, and there are never a lot of people. I've been here probably 4 times now. The trails are also just grass-cut, so also very undeveloped, not good if it's been raining, but great for walking if you're looking for a very soft walk. Bad knees? Definitely walk here.
