Cabo San Lucas has three main beaches. The most popular is Playa Médano, which runs northeast for about 3km (2 miles) from the Hacienda Beach Resort (under renovation). The water is crystal clear and calm, making it ideal for swimming (or, as the case may be, wading with a margarita glasses in hand). Buoyed swimming areas keep the jet skis, parasailers and fishing pangas away from the swimmers (at least in theory), and cruise ships float off shore.
With several bars right on the beach, it's a great place to chill out, pound your favorite cocktails and basically feel merry in the sun.
