When it opened in 1988, Seogwipo Submarine was the first of its kind in Asia the third in the world. Seogwipo Submarine offers safe undersea tours in its recently acquired state of the art submarine from Finland. Munseom, where the submarine travels, is home to outstanding coral reefs, colorful schools of fish, and rich seaweed. The exquisite landscape makes it one of the most beautiful places to dive as well. Going deep into the 40 meter sea-bed, visitors can see countless fish, rare iridescent coral reefs, and a surreal-looking shipwreck with schools of fish surrounding it. Over 20 years of technical knowhow and safe operation (in fact, the longest submarine tour without a single accident on record) make Seogwipo Submarine a must-see attraction on Jeju Island. 

Haenyeo refers to female divers who dive into the ocean water to gather various shellfish, seaweed, etc, without using any underwater diving equipment. When diving underwater, a haenyeo carries only a pair of goggles, a round ball-like tube to keep her balance, and a basket to put her collections in. Such women involved in the fishing industry are known to be scattered all around Jeju-do, Korea, Japan, and Russia. Jeju-do has established the Jeju Haenyeo Museum to introduce to the world the unique activities and culture of Jejudo’s haenyeo female divers.

Situated on the southern tip of the Korean Peninsula, Hallasan is 1,950m in x_height and is the highest mountain in South Korea. Formed from volcanic activity, the mountain is a dormant volcano made mostly of basalt. Home to the magnificent Baekrokdam (lake-filled crater), the mountainside is covered with alpine flora and lush trees. The mountain is characterized by majestic cliffs, steep slopes, interesting rock formations, and, in particular, myriads of colorful azaleas. There are over 360 small mountains (uniquely-shaped volcanic mountains called “Oreum” in Jeju dialect) surrounding Halla Mountain that offer new delights to visitors with the coming of each new season. Along with Hallasan, the oreums were officially named the Hallasan Natural Protection Area (Natural Monument No.12) in 1966. There are six hiking trails along Hallasan. Seongpanak Trail on the east and Gwaneumsa Trail in the north go all the way up to the summit (Baekrokdam). Those looking for a less rigorous hike are advised to take the shorter trails reaching midway up the mountain. All trails are relatively short (less than 10km) and can be hiked in less than a day. Visitors are advised, however, to start early in the morning if planning on hiking up to the summit and to check official operating hours, as some trails are only open during certain hours of the day. Keep reading for information on some of the most popular trails. * Gwaneumsa Trail (North)—Summit Trail Gwaneumsa Trail offers hikers the best view of Hallasan’s deep valleys and stunning terrain.

Lush broadleaf trees give shade from the beating sun and in spring the azaleas bloom and turn the mountainside into a dazzling array of color. * Eorimok Trail (Northwest) This short trail is another relatively easy trail for beginners. In spring, the nearby meadows are adorned with red royal azaleas. From the stone pathway to Mansedongsan visitors can catch a breathtaking panoramic view of the countryside and the island’s signature Oreums. * Yeongsil Trail (Southwest) As the shortest trail in Hallasan, this trail boasts Yeongsilgiam (a spectacular cliff with series of unusual rock formations). It is covered with azaleas and royal azaleas in spring and vibrant autumn foliage starting in October.

Located in the Seogwipo area of Jeju Island, Soesokkak Estuary (쇠소깍) was originally called ‘Soedun’, which means a lying down ox, and it was only later that it became more widely known as ‘Soesokkak’. This is the mouth of the Hyodoncheon stream. As the fresh water meets the ocean, it broadens into wide slow flowing river. ‘Soe; means an ox, ‘so’ means a ‘pool of water’ and ‘Kkak means ‘the end’. Soesokkak Estuary is lined with cliffs of curious lava formations, which are overhung with pine trees. Here the water takes on the deep blue of the ocean, and the scenery is very picturesque. Soesokkak is also well-known for its small, flat wooden boats called “Teu” that have been used for hundreds of years to ferry people across the estuary. The boat is pulled across the estuary by a long rope that is strung between the two banks. Taking a leisurely ride on a Teu across the clear water of the estuary is a great way to enjoy the area’s magnificent scenery.Soesokkak Estuary is located in Hahyo-dong on the Southern side of Hallasan Mountain. The area is also well-known for its tangerines, and visitors are drawn to the area by the fresh scent of the fruit.

Geomum Oreum, with an altitude of 456m, is located in Jocheon-eup, Jeju-si and refers to a parasitic volcano (also called Oreum in Jeju dialect).Geomun Oreum was created by volcanic activities between 100,000 and 300,000 years ago. Lava flow from the crater went along the coastal slope to the Northeast and formed a unique geographical feature called Seonheulgot. The lave flow also formed Bengdwigul Cave on the left side, and Manjanggul, Gimnyeonggul, Yongcheondonggul and Dangcheomuldonggul Caves on the right side. Each of these caves has its own unique features.Upon entering Geomun Oreum, visitors are met by a dense forest filled with Japanese cedar trees.

Sanbangsan Mountain is the result of violent volcanic activity some 700,000 to 800,000 years ago and is in fact a huge body of lava. The cliffs on the southern side of the lava dome are marked with a rich variety of curious formations such as weathering pits and talus scree slopes, some of which are as high as 200m. As its name ‘sanbang’ – literally meaning ‘a cave inside a mountain’ – suggests, this mountain contains a cave, which is located about 150m above sea level and has a spectacular view out over the ocean. Due to its close location to the sea and its high elevation, the peak is often ringed with clouds. The upper slopes of the mountain have their own distinct climatic conditions and are protected for their value for botanical research.The Sanbangsa Temple and also the Bomunsa Temple, which holds the relics of Buddha, are also located on the mountain. Walk along the stone-steps between the two temples and you will find the Sanbanggulsa Grotto. A signal beacon called ‘Yeondae’ in Korean stands at the roadside in front of the mountain, which, in the past, used to fire and smoke to relay urgent messages. Regarding function, it is similar to the more well-known ‘Bongsudae’ signal beacons; but ‘Yeondae’ beacons were built around hilly or coastal areas while ‘Bongsudae’ beacons were built on mountain tops. During the daytime, smoke was used to send warning signals, while fire was used at night.*x_height above sea level: 395.2m/ x_height above ground-level: 345m/ Circumference: 3,780m / Area: 988,332㎡/ Diameter 1,314m
