Manjanggul Cave

만장굴( Manjanggul Lava Tube) Of all the oreum on Jeju, Geomunoreum is the only parasitic cone to be designated as a UNESCO World Natural Heritage site. The oreum holds over 20 caves within its body, although only Manjanggul Lava Tube is open to the public. With its profoundly mysterious and grand appearance, taking a step inside the cave is like stepping into Hades’ underworld. Follow the tunnel of articulate lava rock formations, and you will soon reach a giant rock pillar that indicates the end of the cave. The cave’s temperature fluctuates within 11-21℃ regardless of season, allowing visitors to enjoy the magnificent cave all year round

Hamdeok Beach

If you walk along Jeju Olle Course 19, you will come across Hamdeok Beach, which has an emerald jewel. Hamdeok Beach, located in Hamdeok-ri, Jocheon-eup, Jeju-si, is also called ‘Hamdeok Seoubong Beach’ because of Oreum (Seoubong Peak) standing right next to the beach. It is only 20km away from Jeju Airport, but the moment you arrive here, you feel like you are in another country. The tall palm trees that welcome you from the entrance, the emerald sea that contrasts with the white sand, the clear water and white waves that make even the sand and seaweed transparent are like that. Among the numerous beaches in Jeju Island, if you choose three places with the most beautiful sea color, it is definitely Hyeopjae Beach, Gimnyeong Beach, and Hamdeok Beach. The water is clear and the water depth is shallow, so it is also a good summer resort for families. The west side of the beach is connected by an overpass, so you can experience walking on the sea.
