Tucked just north of the Julia Tuttle eastbound on-ramp sits dog-friendly Martell Park (also known as the "Martell Bark Park" in some circles). Although the enclosed pooch playground area is small in size, it still packs a big bark. Unlike at more traditional dog parks, big and little pooches do not have separate areas here; everyone is expected to just get along. And why not? In addition to the overarching mellowness of the dogs and their owners, the park boasts a million-dollar view of the causeway and Miami Beach. A word of caution: There's not much in the way of close-in parking here, but it's easy enough to find something in the surrounding blocks. Just don't use the Taco Bell lot, or you and your pup could be hoofing it home — and paying big bucks at the tow lot.
