Soyosan Mountain and Jajaeam Hermitage — The Horseshoe Ridge Left by Master Wonhyo in 654

Soyosan Mountain is a 587-meter-high mountain spanning Dongducheon and Sinbuk-myeon in Pocheon, Gyeonggi Province. It is famous for Jajaeam Hermitage, associated with the legends of Master Wonhyo and Princess Yoseok, and its horseshoe-shaped ridge encircled by six peaks. Cultural heritage admission fees were fully abolished in 2023, and the site is now open free of charge. From Exit 1 of Soyosan Station on Subway Line 1, you can walk to the trailhead.

The Summit Encircled Like a Horseshoe by Six Peaks: Uisangdae at 587 m

Soyosan is a 587-meter-high mountain spanning Sangbongam-dong in Dongducheon, Gyeonggi-do, and Sinbuk-myeon in Pocheon. It is designated as one of Korea's 100 Famous Mountains and as a national tourist destination. The ridgelines of its six peaks—Habakundae, Jungbaekundae, Sangbaekundae, Nahan-dae, Uisangdae, and Gongjubong—surround Jajaeam Temple and the valleys in a horseshoe shape. Hiking the full loop around this ridgeline is considered the standard Soyosan trekking route.

The mountain is famous for the story of Master Wonhyo and Princess Yoseok, but the actual summit is Uisangdae, not Wonhyodae, and the place honoring Princess Yoseok is the separate peak of Gongjubong. Although the mountain landscape is not especially imposing, the full loop taking in all six peaks is a challenging course that takes more than four hours. In spring, azaleas and royal azaleas bloom, while large and small waterfalls, including Wonhyopokpo, Cheongnyangpokpo, and Okryupokpo, continue along the valleys.

Jajaeam Temple, Said to Have Been Founded by Master Wonhyo in 654: Fires and Reconstruction

Jajaeam Temple, on the slopes of Soyosan, is recorded in the Encyclopedia of Korean Culture as having been founded by Master Wonhyo in 654, the first year of King Muyeol of Silla. However, Dongducheon City's explanation of the origin of the local name states that Master Wonhyo established Soyoam, now Jajaeam, in 645, the 14th year of Queen Seondeok's reign. Thus, two records have been handed down regarding the temple's founding date.

The temple's name is said to derive from the story that, after Master Wonhyo formed a relationship with Princess Yoseok, he resisted the temptation of a woman who appeared after Guanyin Bodhisattva transformed herself, becoming a person who followed his own will—in other words, a person free from all constraints. In 974, the 25th year of King Gwangjong's reign, Master Gakgyu rebuilt the temple under the orders of the retired king. In 1153, the seventh year of King Uijong's reign, it was destroyed by fire, and only the main hall and monks' quarters were restored as the temple continued to exist. In 1872, the ninth year of King Gojong's reign, Wongong and Jeam rebuilt it and renamed it Yeongwonsa. In 1907, another fire destroyed all the buildings except Manwolbojeon Hall. In 1909, Seongpa and Jeam rebuilt the temple and restored its original name, Jajaeam. The buildings that remain today were rebuilt in 1961. The temple was designated Dongducheon Local Cultural Heritage No. 8 in 1986, and in 1994, an annotated Korean translation of the Essentials of the Heart Sutra was discovered in the hermitage and designated Treasure No. 1211.

The Name “Soyo” and Its Designation as a National Tourist Site in 1981

Soyo means to wander leisurely or stroll without hurry. A widely circulated story says that the name came from the fact that Hwadam Seo Gyeong-deok, Bongnae Yang Sa-eon, and Maewoldang Kim Si-seup wandered on this mountain, but this is classified as an unverified folk tale. According to Dongducheon City's explanation of the origin of the name Soyodong, the area began to be called Soyo after Master Wonhyo built Soyoam on Soyosan.

As an administrative district, Soyodong once belonged to Idam-myeon of Yangju County during the Joseon period. It annexed Sangbongam-ri in 1981 and merged with Dongandong in 1998. Around the same time, Soyosan was designated a national tourist site by the Korea Forest Service because of its beautiful scenery, including Sangbaekundae, Habakundae, and Jungbaekundae, and its popularity among hikers.

May 4, 2023: The Day the Ticket Booth Fee Schedule Disappeared

There used to be a ticket booth at the entrance to the Soyosan tourist site that collected cultural heritage viewing fees. The fee schedule, which listed 2,000 won for adults and 600 won for teenagers until the previous day, disappeared on May 4, 2023, when the cultural heritage viewing fees at 65 temples affiliated with the Jogye Order of Korean Buddhism were abolished nationwide. The collection of temple cultural heritage viewing fees was abolished after 61 years, following the enactment of the Cultural Heritage Protection Act in 1962.

A Dongducheon City official said that complaints from hikers about the fee had been frequent and expressed hope that its abolition would help revitalize the stagnant tourist area. The ticket booth building remains, but everyone can pass through without paying a separate fee. There are also no designated entry hours, so the site is open at all times.

From a Flag Stop in 1976 to a Smart Railway Station: Soyosan Station

The easiest way to reach Soyosan is by subway. Soyosan Station began operating as a flag stop on January 11, 1976, and its former station building was completed on September 21, 1982. The old station, with its octagonal roof, was said to have had enough atmosphere to be introduced in middle-school Korean-language textbooks. It was rebuilt as a modern station when Seoul Subway Line 1 was extended here on December 15, 2006.

On December 16, 2023, Line 1 was extended again to Yeoncheon Station via Cheongsan and Jeongok stations, although some trains still originate and terminate at Soyosan Station. Exit 1 of Soyosan Station is about a 10-minute walk from the trail entrance. Buses 36 (Soyosan–Suyu Station), 39 (Jeongok–Dobongsan Station), and 53 (Jeongok–Deokjeong) can also be boarded in front of the station. By car, drive about 5 km north from Dongducheon City Hall along National Route 3. The address of Soyosan National Tourist Site is 406-65 Pyeonghwa-ro 2910beon-gil, Dongducheon-si, Gyeonggi-do.

From a One-Hour Jajaeam Course to a Four-Hour Full Loop

The Soyosan hiking map shows four courses by difficulty. The course from the management office ticket booth through Iljumun Gate, Baegunam, and Jajaeam, then around Habakundae, Jungbaekundae, and Seonnyeotang before descending, is 5.71 km and takes 1 hour 30 minutes. Including Sangbaekundae makes it 6.21 km and 2 hours 30 minutes, while adding Kalbawi, Nahan-dae, and Geumsonggul makes it 6.89 km and 3 hours. The full loop including Uisangdae and Gongjubong is 8.19 km and takes 4 hours.

To climb toward Jajaeam, you must ascend a steep staircase extending 0.7 km to Habakundae. In the opposite direction toward Gongjubong, you must climb continuously for 1.0 km from Gujeolteo to Kkalttak Pass. The Palgakjeong course, which begins at Palgakjeong Pavilion opposite Soyosan Station, follows a gentle forest path and is accessible and not difficult. It is recommended even for beginner and intermediate hikers. Dongducheon City rates the overall difficulty of Soyosan as intermediate to advanced.

Freedom Protection Peace Museum and Gyeonggi Northern Children's Museum

At the entrance to Soyosan stands the Freedom Protection Peace Museum, which opened in 2002. It was built to honor the contributions of the 21 countries whose troops participated in the Korean War. The museum includes a planning exhibition and archive on the first floor, artifacts from UN troop-contributing countries on the second floor, and a war video hall and the Lee Ho-wang Memorial Hall on the third floor, along with large outdoor exhibits such as aircraft. Visiting hours are 10:00–18:00 from March to October and 10:00–17:00 from November to February. It is closed every Monday, New Year's Day, Lunar New Year's Day, and Chuseok.

Next door is the Gyeonggi Northern Children's Museum, opened by Dongducheon City on May 4, 2016, and operated by the Gyeonggi Cultural Foundation since January 1, 2020. Under the theme “Children Dreaming in the Forest,” interactive exhibitions such as Dinosaur Forest, Oreum Forest, and Sea Forest are divided between the first and second floors. Admission to the permanent exhibitions is free, but visits are available only by 100% advance reservation, in four daily sessions at 10:00, 12:00, 14:00, and 16:00, with each session lasting 90 minutes. The museum is closed every Monday, January 1, Lunar New Year's Day, and the day of Chuseok.

Soyo Autumn Foliage Culture Festival in Late October, the Most Spectacular Foliage Season

Soyosan has long been regarded as a mountain with spectacular autumn foliage, earning it the nickname “Geonggi's Sogeumgang.” In an average year, the foliage is said to peak from after October 26 through early November. Every year in late October, the Soyo Autumn Foliage Culture Festival takes place around the Soyo Outdoor Music Hall, featuring a procession honoring General Eoyuso, lion dance performances, hands-on activities, and food stalls.

In spring, azaleas and royal azaleas color the ridges, while in summer, vacationers flock to the streams flowing along the hiking trails. Many visitors say that coming in the morning during foliage season is relatively quiet and the air is clear. It is also often advised to bring a light jacket and hiking poles to make the descent more comfortable.

What First-Time Visitors Miss: Slippery Rocks and Gunshots

Soyosan is not especially steep, but rocks are slippery in places along the trail and some sections have widely spaced stones. Various hiking guides repeatedly warn that first-time visitors and those unfamiliar with mountain hiking should take care to avoid falls. The rocky paths beside the valleys become even more slippery immediately after rain, so wearing hiking shoes is recommended.

There are many military bases around Dongducheon, so it is worth knowing in advance that you may hear gunshots or aircraft during your hike. This may be disappointing for visitors expecting only a quiet mountain walk, but the mountain's clear advantages include its accessibility on foot from the subway station and its range of courses, from one hour upward, allowing visitors to choose anything from a light stroll to a full traverse according to their fitness level.

Dongducheon City's Vision for Soyosan's Next Decade

Dongducheon City is promoting the “Soyosan Expansion and Development Project” in accordance with the pledges of Mayor Park Hyeong-deok during his eighth elected term. In 2023, a service project to establish development measures and a master plan for Soyosan surveyed the current status of approximately 500,000 square meters around the mountain. A total of 24 detailed projects are being pursued over the short, medium, and long term.

The plan includes creating Soyo Naeum Park near the Freedom Protection Peace Museum by 2029, with memorial and rest areas. It also includes developing themed shops, stream restoration, a waterfront park, accommodation facilities, and other amenities from the tourist-site entrance to the former Soyo Resort area. The goal is to transform Soyosan from a place centered on hiking and walking into a destination where families can stay for longer periods.
