You can't drive along the best mile of Palm Beach County; you have to walk or ride your bike. The town of Palm Beach is located on a barrier island, and tucked behind the mansions on the Intracoastal side, you'll find the Lake Trail, a paved path where you might bump into trust-fund kids on rollerblades or island residents walking immaculately groomed poodles. Pick up the trail from any of the cul-de-sacs that branch off North Lake Way and head north. To your right, you can catch a sneak peek into the backyards of fabulous estates; to your left, see captains parking their yachts and get a panoramic view of West Palm Beach's sherbet-colored skyline. If you follow the trail to its miles-later end at the Sailfish Club and zigzag along the residential streets, you will reach a small dock overlooking the Palm Beach Inlet; you can't go any farther without swimming. Drink from the water fountain that greets you like an oasis, have a seat on the dock, and watch ships roll past Singer and Peanut Islands.
