If you're staying on the beach side of Singer Island, you can stroll through the surf down the beach to the inlet. At the Marriott there is a paved walk following the inlet from the Atlantic back to Lake Worth. The walkway is nice and there is a shelter with benches midway to the Lake. Amazing just across the inlet are the mansions of West Palm Beach. There is a paved walkway running down the center of the island that extends from the inlet to the shopping center. Sailfish Marina is about halfway down. The shop sells fish food to feed the masses of fish waiting at the dock for the well trained tourists to come, feed them, and view the feeding frenzy. The Marina has a view of the Lake and Peanut Island.
