Gugok Falls (구곡폭포) is located near Bonghwasan Mountain in Chuncheon-si, Gangwon-do. The falls twist and turn nine different times before dropping down from a huge stone wall, ending in a magnificent 50m cascade. The falls are surrounded by interesting rock formations, one of which includes the Haneulbyeokbawi Rock.Gugok Falls was designated as one of Chuncheon city’s official tourist attractions on February 13th, 1981. From the ticket office located at the entrance, it takes about 20 minutes to get to the falls on foot. In winter, the waterfalls are very popular among hikers because, when frozen, the x_height and the sheer size of the falls are perfect for ice climbing. If you hike through a nearby jae (a small mountain pass) named "Kkaldakgogae (깔닥고개)", you will come across a natural Munbae village where you can enjoy Sanchaebibimbap (mixed rice with seasoned wild vegetables) and traditional liquor.

Gwangseongbo Fortress’s outer wall from the Goryeo era was mended in 1618. The fortress was built in 1656 and the outpost was constructed in 1679. It was completely remodeled into a masonry castle with gates in 1745. During Sinmiyangyo (the American invasion in 1871), Gwangseongbo was the fiercest battle ground in Ganghwa. On April 24, 1871, a fleet with 1,230 American naval forces led by Rear Admiral John Rodgers landed on Ganghwado Island to demand the opening of Korea's ports and commerce. The armed forces attacked Chojijin Fortress and Deokjinjin Camp, then marched to Gwangseongbo Fortress, where they engaged in close combat with the warriors of Joseon. Although General Eo Jae-yeon and the other warriors were poorly equipped with far inferior weapons, they bravely fought to the death against the invading forces.The battlefield ruins of the fortress and the gate towers such as Anhaeru, Gwangseongdon, Sondolmokdon, and Yongdudon were repaired in 1977. The twin tombs of General Eo Jae-Yeon and his brother Eo Jae-seon, along with the anonymous tombs of warriors who died on the battlefield were also honorably arranged at the same time. Furthermore, a stone monument commemorating the restoration of Ganghwa Battlefield was erected on Yongdudondae Post.In 1988, an extensive rest area was created toward the shore for visitors’ convenience. Gwangseongbo Fortress is presently designated as Historical Relic No. 227. A religious service known as Gwangseongje is held annually to commemorate the patriotic spirits of General Eo Jae-yeon and other unnamed warriors. This service takes place at 11 a.m. on every April 24th of the lunar calendar.

Odusanseong Fortress (오두산성) is built around the strategic summit of the mountain. Its walls stretch across roughly 620 meters and were built during the Baekje Dynasty. The fortress is built on the intersection of the Imjingang River (임진강) and the Hangang River (한강) on the summit of Odusan Mountain (오두산, 119 meters). The mountain’s slope is steep and stones used in the construction of the fortress walls are scattered here and there at the summit. These scattered stones are evidence that the fortress underwent repairs several times during the Samguk (Three Kingdoms) era and the Joseon Dynasty, as these stones were evidently quarried and used to mend the fortress walls. Excavations have discovered a great deal of earthenware, white porcelain, tile, and iron arrowheads. Topographically, the fortress sits on a prime strategic junction and the Unification Observatory has been situated there as well. The fortress stands as an important object of study concerning fortifications and structures from the Baekje Dynasty. It has been recorded on the stele of King Gwanggaeto, samguksagi (History of the Three Kingdoms), in the baekjebongi (Baekje Annals) and on daedongyeojido (Map of Korea) that the fortress was the Gwanmi Fortress of Baekje, attracting many scholars and researchers interested in this period.
