Condado Beach is the main reason the neighborhood exists — a wide Atlantic-facing strand that runs for roughly a kilometer between the hotel towers of Ashford Avenue. The water is warm year-round, and the beach draws a genuine mix of hotel guests, local families on weekends, and surfers who work the modest breaks near the west end. Parking is difficult; most people walk or take a rideshare.
The beach itself is public, but chair rentals are controlled by the adjacent hotels and can be expensive. The free solution is to show up early, pick your spot in the unclaimed stretches between hotel frontages, and head back to your rental before checkout time. The best swimming is in the calmer water near the center; closer to the Condado Lagoon inlet the currents can be unpredictable. Vendors work the beach selling coconut water, piraguas (shaved ice), and cold drinks, which is all you really need.
