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.

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

성산일출봉(seongsan illchulbong) Seongsan Ilchulbong Tuff Cone, a landmark attraction of Jeju, was formed about 5,000 years ago from an eruption of magma on the ocean floor. It is especially famous as a sunrise viewing spot, known to be one of the top ten exquisite sceneries of Jeju Island.Besides viewing the sunrise, Seongsan Ilchulbong Tuff Cone is also known to be an excellent trekking spot. The Seongsan-Ojo Trail connects two villages by crossing the peak. Another popular trail, the Jijil Trail, offers a closer look at the UNESCO-designated geopark as well as Jeju’s local culture. Walking along one of these paths is recommended to really experience the area; walking all the way to the summit offers views of both the vast volcanic crater in the center and the blue ocean surrounding the area. To complete your trip, head to Seongsanpo Port to watch haenyeo (female divers) at work.

광치기 해변(Gwangchigi Beach) Gwangchigi Beach boasts one of the most pristine and spectacular views along Jeju's coastline. In the distance is Seongsan Sunrise Peak, a UNESCO World Natural Heritage site and jewel of Jeju Island.  In the area are many trendy cafes and restaurants, as well as travel accommodations and fun things to do with the family, like the Aquaplanet Aquarium. It is also where Olle walking trails 1 and 2 connect.

정방폭포( Jeongbangpokpo Falls) Seogwipo, which includes the entire southern half of Jeju, exhibits a great amount of sunshine and warm temperatures, attracting crowds of tourists all year round. One attraction many people choose to visit is Jeongbangpokpo Falls, one of the top three waterfalls on Jeju Island. The water falls 23 meters straight down off the cliff and into a pool before flowing to the sea.Located on the cliff behind Jeongbangpokpo Falls is Waljong Art Gallery. This gallery is dedicated to the Korean artist Lee Wal Jong, who settled in Jeju decades ago. The gallery is filled with his inspiring artworks, expressing the beauty of Jeju in his own unique way. The strategic location and glass-walled second floor also offer visitors an amazing view looking over the sea.

외돌개 (Oedolgae) Oedolgae, the starting point of Jeju Olle Trail Course 7, is a stone pillar that rises 20m high from the sea. Standing alone on the sea, it was named ‘Oedolgae’. It is also called ‘General Stone’ and ‘Grandma Rock’, and there is a story that General Choi Yeong decorated this rock like a general when fighting against the Yuan Dynasty and made the enemy self-destruct. For the origin of the name 'Grandma Rock', read the legend below. Not only the visible rocks, but also the life of Jeju people waiting for the people of the sea can be seen.
