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.

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.
