There is an endless list of attractive beaches in the Bay of Pigs, so you can spend several days at the beach in the area, and simply enjoy the excellent sandy coast and warm waters of the bay surrounded by pure nature. Just walk out of Hostal Kiki Hostal and you have it at your feet.
If it rained a lot of rain, the water may be somewhat red due to organic compounds which reach sea through the nearby rivers. At this point there are alternatives: Playa Larga and Playa Giron, both equally attractive!
