Begin your day with a boat tour around the bay, where you can admire the limestone karsts rising from the emerald-green waters. Marvel at the unique rock formations and take plenty of photos to capture the breathtaking scenery. After the boat tour, head to Koh Hong, a picturesque island known for its crystal-clear waters and pristine beaches. Spend the afternoon swimming, snorkeling, or simply relaxing on the beach. In the evening, enjoy a delicious seafood dinner at one of the local restaurants, where you can savor the fresh catch of the day.
