Spend the day at Tangke Saltwater Lagoon, a hidden gem surrounded by towering limestone cliffs. Take a dip in the emerald-green waters and marvel at the natural beauty of the lagoon. Afterward, head to Antonia Beach, a secluded paradise with powdery white sand and calm waters. Enjoy beach activities like beach volleyball, kayaking, or simply unwind with a book under the shade of a palm tree.
