Puntarenas Costa Rica
This beach is opposite Golfito, and the view of the bay, port and the surrounding rainforest is worth the short boat-ride out here. As for swimming, although it's cleaner than the polluted waters just off the town, the water isn't pristine. This is not the Golfo Dulce proper, and although efforts have been made to clean up trash, you're still near a dock visited by freighters.
