Situated in Sanpo-ri (Uljin), Mangyangjeong is a beautiful pavilion near Mangyang Beach. King Sukjong of the Joseon Dynasty, upon seeing the paintings of the “Eight Scenic Sights in Eastern Korea,” picked the pavilion as the best one among them; he wrote Gwandongjeilru (the best pavilion in Eastern Korea) by himself and let it hang in the pavilion. While it was located in Hyeonjongsan (Mt. Hyeonjong), Mangyangjeong was moved to the current spot in 1858 and rebuilt in 1958. Surrounded by lush pine trees, the pavilion lets visitors overlook Mangyang Beach, Wangpicheon Stream and the sea. It has also been a renowned spot to see the sunrise and the moon. The name, Wangpicheon Stream, originates from the fact that the King found a refuge there or that he stayed there for summer vacation. Mangyang Beach has a shallow depth and narrow x_width, but it is relatively warm among beaches on the East Coast. Surrounded by pine trees, the beach is quiet year-round, making it a pleasant site to walk around. When the waves are calm, visitors can see Turtle Rock prostrating itself on the sea. The beach is a popular destination for summer travelers thanks to numerous nearby attractions including Seongryugul (Natural Monument No. 155) and Bulyeong Valley.
