How to Connect a Coal Mine Tunnel and a Goguryeo Fortress in One Day at Mungyeong Eco World

Why a coal mine and filming sets coexist on a 1.03-million-square-meter site

Mungyeong Eco World is a complex tourist destination covering approximately 1.03 million square meters and combining the Coal Museum, Eco Town, Gaeun Open Set, monorail, Giant Forest, and more. Mungyeong City created it as a recreational and cultural space themed around ecology, green energy, and the environment by combining Baekdu Daegan ecological resources with video and cultural content.

Its current composition resulted from adding Eco Town and outdoor experience facilities to the existing Mungyeong Coal Museum and Gaeun Open Set. Therefore, rather than simply being an amusement park, this place is closer to a destination where industrial memories of a former mining region, forest ecology, and drama-filming spaces can be encountered along one admission route.

Gaeun’s industrial landscape left behind after the mine closed in 1995

The Eco World Coal Museum presents exhibits on the coal industry and miners’ lives, while the Mine Gallery Experience Hall uses an actual mine tunnel to let visitors experience the mining environment. A mine journey aboard the Spider Train is also offered, making the experience different from an itinerary focused only on museum exhibits.

Gaeun Double-Deck Bridge in Mungyeong, along the road to Eco World, was built in the early 1950s and lost its original function when the mines in the area closed in 1995. It is a structure that illustrates the background behind the formation of Gaeun’s tourism spaces around its coal-mining heritage. It is currently introduced as one of only two such bridges remaining in Korea, together with the Jangseong Double-Deck Bridge in Taebaek.

An order for seeing everything from Mungyeong Coal Museum to Gaeun Open Set

The facilities are introduced as four zones: the Coal Museum, Eco Town, Giant Forest, and Gaeun Open Set. Reviews centered on visits with children suggest a course of approximately three to four hours, but reviews covering the mine experience, Spider Train, monorail, photo studio, and Gaeun Open Set mention that a full day was needed.

Gaeun Open Set features a Goguryeo fortress, an old village, and a market scene. Since it has been used as a filming location for Taejo Wang Geon, Da Joyeong, Sungkyunkwan Scandal, Chuno, Gwanggaeto, The Great, Goryeo–Khitan War, Moon Embracing the Sun, The Rebel, and Kingdom Seasons 1–2, it is best not to view the historical sites and actual filming sets in the same way.

Kids Tongtong at Eco Town and VR experiences with a 130 cm height requirement

Indoor Eco Town includes Eco Farm, where visitors can observe fruits and vegetables, and Kids Tongtong, an indoor air-bounce facility. Visitors looking for children’s spaces can plan a course centered on these two facilities even on days when outdoor activities are difficult.

Eco World has indoor children’s play facilities such as a rotating automatic car ride, mini train, four-season sledding area, and safety experience zone, as well as an outdoor playground and a children’s train. The VR experience zone for teenagers and adults requires a height of at least 130 cm, while the survival game area requires at least 140 cm, so the heights of all family members should be checked first.

Actual conditions for playing in the water at the 30 cm Paper Boat Pond

The outdoor water-play area, Paper Boat Pond, has a water depth of 30 cm and operates from 10:00 a.m. to 5:30 p.m., according to the notice dated June 16, 2025. Visitors must take a 10-minute break after each 50-minute session, so it should not be regarded as a facility where visitors can remain in the water continuously.

Paper Boat Pond and the hands-on play facility Mysterious Faucet can be used with a guardian accompanying the child, and operation may be adjusted according to weather conditions. Dedicated water-play shoes are permitted, but admission may be restricted for visitors wearing regular shoes. Outdoor restrooms, a first-aid room, and an open-air wash area are available on site. Parasols, tents, and the Wangneung-ri snack shop are also listed.

Finding Yongduri Super from Queen of Tears across from the water-play area

Across from the water-play area is the permanent Yongduri Super exhibition facility from the tvN drama Queen of Tears, according to the notice dated June 16, 2025. A specific advantage of this facility is that companions who do not participate in the water activities can also view filming-related content in the same area.

Gaeun Open Set is an outdoor space recreating a Goguryeo fortress, an old village, and a market, so it is difficult to say that it is unaffected by weather like an indoor experience facility. Since operation of the water-play area also varies with weather, even during a summer visit it is safer to plan the Coal Museum and Eco Town alongside the outdoor zones rather than making the outdoor areas the sole purpose of the itinerary.

Calculate the seasonal closing times and admission fees first

Operating hours vary by season. From April to September, hours are 10:00–19:00 on weekdays and 09:00–19:00 on weekends and public holidays, with admission ending at 18:00. From October to November, hours are 09:00–18:00 daily, with admission ending at 17:00. From December to January, hours are 09:00–17:30 daily, with admission ending at 16:30. From February to March, hours are 09:00–18:00 daily, with admission ending at 17:00.

As of 2026, regular admission is 10,000 won for adults, 9,000 won for children and teenagers, 5,000 won for seniors, and 5,000 won for Mungyeong residents. Group admission is 9,000 won for adults and 8,000 won for children and teenagers, while children under 36 months enter free. Mungyeong residents and visitors eligible for free admission must present identification, and the monorail fee is listed as free on the official fee table.

The facilities are listed as open year-round. Ticket holders are announced as being allowed to re-enter on the same day, although this may change depending on on-site conditions. Tour Pass holders can use Eco Town without an additional fee.

Traveling to 114 Wangneung-gil via Jeomchon from Dong Seoul Terminal

For first-time visitors using public transportation, the recommended route is to take an intercity bus from Dong Seoul Comprehensive Bus Terminal to Jeomchon. It is introduced as taking approximately 40 minutes by city bus from Mungyeong Bus Terminal to Eco World, but the current materials do not provide a bus route number or the walking time after getting off.

Gaeun Ajagae Market Bus Stop is introduced as a nearby information point, and its contact number is 054-572-7100. Intercity bus inquiries can be made at Dong Seoul Comprehensive Bus Terminal at 1688-5979. By car, travel from Mungyeongsaejae IC on the Jungbu Naeryuk Expressway toward Sangju and Mungyeong, then enter via Mogok Junction, Mungyeong-daero, Gaeun-ro, and Wangneung-gil.

The address is 114 Wangneung-gil, Gaeun-eup, Mungyeong-si, Gyeongsangbuk-do. Reviews mention that the dedicated parking lot across from the entrance was spacious and free, but the official parking capacity and current fees have not been provided. Reviews stating that parking was free should be understood as information from 2020.

What to confirm at 054-572-6854 and the limits of a one-day itinerary

Eco World’s main telephone number is 054-572-6854, and the official website is https://www.mgtpcr.or.kr/web/page.do?menuIdx=687. Operating hours vary by season, and the actual operating status of some content, such as the VR experience zone, may change. If you are visiting for a specific experience, it is best to adjust your itinerary before departure based on this number or the official website.

For a child-centered visit, allowing three to four hours and combining the Coal Museum, Eco Town, and play facilities is realistic. Seeing everything from the mine experience, Spider Train, Gaeun Monorail, and Giant Forest to Gaeun Open Set may require a full-day itinerary. Public information does not confirm wheelchair and stroller accessibility or rentals, filming-restricted areas, English information or audio guides, or whether cash-only payment applies.
