At Sibang Ferry Terminal, boats to Isudo operate six times a day. During busy times, trips are frequent, so there is no need to worry, but on Wednesdays, service ends at noon. Isudo means 'island of beneficial water.' The area is a spawning ground for codfish and becomes an anchovy fishing ground in spring. Due to the abundance of fish species that provide income for locals, it was named Isu (meaning beneficial seawater) in Chinese characters. There is also the Sibang Ferry Terminal open-air camping zone, which is quiet due to few visitors, allowing for a peaceful time, and the campsite offers views of the sea. Additionally, there is a well where visitors can quickly wash off after water activities.
Maemiseong Fortress is a wall that was built alone by citizen Baek Soon-sam to protect crops from natural disasters, who lost arable land to Typhoon Maemi in 2003. Repeatedly stacking square stones near the beach and filling them with cement has now become a castle reminiscent of medieval times in Europe. Its scale and design are so great that it is hard to believe that it was built without a single blueprint.
Geoje Maemiseong is a fortress wall built by Baek Sun-sam, who lost his livelihood due to Typhoon Maemi in 2003, to protect his farmland from natural disasters. After the farmland was lost to the typhoon, he personally stacked square stones one by one near the beach and filled the gaps with cement, building the fortress alone over a long period. Maemiseong, born this way, is not just a simple breakwater or fence but has a unique appearance reminiscent of medieval Europe. It creates a rare exotic atmosphere, and thanks to this distinctive scenery, Maemiseong has become one of Geoje's tourist attractions, with many photo spots throughout, making it a popular place for visitors to take memorable photos.
Dumo Mongdol Beach offers excellent views with Gatseom, a small rocky island, on the left and Isudo Island on the right when looking out from the beach. At sunrise, the islands in the front sea and many birds create a picturesque scene, attracting photographers. Unlike other mongdol (pebble) beaches, the side facing the sea is sandy while the other side is covered with pebbles. When the tide is low, visitors can experience mudflat activities like clam digging. The water is shallow and gentle, making it ideal for children to play, so it is mainly visited by family travelers. It is a popular destination for those seeking relaxation and sea experiences away from the city.
Geoje was severely invaded by Japanese pirates, and in the early Joseon Dynasty, seven military camps were established, with Jangmokjin being one of them. Since its reconstruction in 1785 (the 9th year of King Jeongjo), it has undergone several repairs. From 1914 to 1953, it was used as the Jangmok-myeon office. The current building was dismantled and restored in 1982. A guesthouse (gaksa) served as lodging for officials on duty or important guests visiting the county and housed a space in the center for the royal plaques symbolizing the king. The present Jangmok Guesthouse is enclosed by a wall and gate, with no auxiliary buildings remaining, only the main hall. It features round-shaped tapered columns on the outer perimeter and square columns elsewhere, with only a stone foundation built of rough stones remaining. Since Jangmokjin is located at the northern end of Geoje, it was a strategic key point essential for defending the Jinhae Bay area.
