Discovering the Principles of Water While Gazing at the Tamjin River: Jeongnamjin Water Science Museum

Why Water Was Collected in the Four-Story Building at 20 Haengwon-gangbyeon-gil

Jeongnamjin Water Science Museum is a water-themed science museum located at 20 Haengwon-gangbyeon-gil, Jangheung-eup, Jangheung-gun, South Jeolla Province, Korea. The official Jangheung-gun tourism page introduces it as an exhibition and visitor facility where guests can experience the science of water that moves the Earth through the power of a single drop of water. The building is described as having four floors.

The exhibitions present water through ecology, energy, and play. The first floor has an aquarium and touch pool; the second floor has the Water Science Experience Hall, 4D Theater, and Hydrothermal Energy Promotion Hall; the third floor has the Water Classroom; and the fourth floor has a restaurant area. It is therefore more than simply a facility for viewing fish.

As of 2026, 09:00–18:00, with Admission Until 17:00

As of 2026, the opening hours listed by Jangheung-gun are 09:00–18:00, while the Jangheung Festival and Tourism Foundation lists 17:00 as the admission closing time. If you arrive just before 5 p.m., it will be difficult to view all four floors thoroughly. Based on visitor reviews, seeing the entire facility takes about one hour.

Closed days are every Monday, January 1, the day of the holiday, and the day after a public holiday. Although the facility is listed as open year-round, separate closing rules apply, so it is safer to avoid planning a visit on Mondays or the day after a Korean public holiday.

The main telephone number is 061-863-0051. The official information page is the Jeongnamjin Water Science Museum listing on the Jangheung-gun tourism website. For details that may change, such as whether the 4D Theater is currently operating, calling this number before departure is the most direct option.

From an Adult Admission Fee of 3,000 Won to Free Admission for Jangheung Residents

As of 2026, individual admission fees are 3,000 won for adults, 2,000 won for teenagers, and 1,000 won for children. Group fees are listed as 2,500 won for adults, 1,500 won for teenagers and soldiers, and 700 won for children, so group visitors should calculate their fees separately from individual rates.

A separate information source lists Jangheung resident fees as 1,500 won for adults, 1,000 won for teenagers and soldiers, and 500 won for children; visitors aged 65 and over enter free. Since these rates are presented for Jangheung residents, foreign travelers can budget according to the regular individual rates of 3,000 won for adults, 2,000 won for teenagers, and 1,000 won for children.

The available information does not clarify whether only cash is accepted, whether experience programs have additional fees, or how many people are required for group admission. To make it easier to ask which areas are covered by the admission ticket and which experiences cost extra, note the facility names “4D Theater” and “Water Classroom.”

Order for Meeting Chinese Softshell Turtles and Doctor Fish in the First-Floor Aquarium

It is best to start on the first floor. It has an aquarium and touch pool, while an eco-friendly aquarium area has been created for observing marine life and experiencing media art. Various fish are displayed in wall-mounted tanks, and fish and Chinese softshell turtles can be seen in the circular tank.

The Korea Tourism Organization’s visitor information introduces fish feeding and a doctor fish experience as activities available on the first floor. However, the operating hours, participation age, and additional fees for these activities are not provided in the information materials, so they should not be assumed to be permanently available on a walk-in basis.

Because this area involves viewing fish and the touch pool at close range, visitors with children should first check whether they are permitted to put their hands in the water. The registered exhibition list includes a touch pool, circular aquarium, wall-mounted aquariums 1 and 2, and several other aquariums.

Allow Separate Time for the Siphon Exhibit and 4D Theater on the Second Floor

At the Water Science Experience Hall on the second floor, visitors can operate scientific instruments themselves and learn the principles of water. The exhibit “How a Siphon Works” was manufactured by GL Associates in 2013. It lets visitors experience how water flows from a higher place to a lower place through a curved tube without external power.

The second floor also has the 4D Theater and Hydrothermal Energy Promotion Hall. At the latter, visitors can learn through a ball-based game how hydrothermal energy heating is supplied using river water. One information source lists 4D screenings at 11:00, 14:00, and 16:00.

A 2025 travel review recorded the 4D experience as lasting about 15 minutes and said that viewing the entire building took about one hour. However, the current status of the 11:00, 14:00, and 16:00 schedule has not been confirmed. If you are aiming for a specific screening, call 061-863-0051 to inquire.

The Water Classroom on the Third Floor and Views of the Tamjin River from the Fourth Floor

The third floor has the Water Classroom, introduced as a space for interactive games and virtual experiences. Listed programs include a fish ecology puzzle, making a mini mood lamp, making your own umbrella, drawing your own fan, coloring activities, making an eco-bag, decorating a tumbler, and making beaded bracelets and necklaces.

These craft programs were included in a 2026 children’s travel-course guide, but operating dates, material fees, and reservation requirements for each program were not provided. Foreign families should therefore avoid assuming that the programs are always available and ask whether the third-floor Water Classroom is operating before entering.

The fourth floor has a restaurant where, according to the information provided, visitors can dine while looking out over the open scenery of the Tamjin River. If you plan to spend about an hour touring the museum, decide in advance whether to include a fourth-floor meal, and do not assume that the restaurant’s hours are the same as the museum’s operating hours.

Transportation Information That Is Difficult to Use Directly from Jangheung Station or an Airport

The address is 20 Haengwon-gangbyeon-gil, Jangheung-eup, Jangheung-gun, South Jeolla Province, Korea, and the listed coordinates are latitude 34.686038 and longitude 126.900108. The official materials currently available do not include connecting routes, alighting stops, exit numbers, or walking times from Jangheung Station, the bus terminal, or an airport that foreign visitors might use as their starting point.

Therefore, this article does not provide an unverified public-transit route stated as “take bus number X.” After traveling to Jangheung-eup, foreign visitors can realistically enter the address exactly into a map app and show “20 Haengwon-gangbyeon-gil, Jeongnamjin Water Science Museum” to a local bus driver or taxi driver.

Parking information conflicts between sources. The official Jangheung-gun tourism page says there is no parking lot, while another tourism information source says parking is available and free. If traveling by car, do not assume that free parking is available; call 061-863-0051 before departure to confirm whether parking is possible and where it is located.

Wheelchair Access and What Foreign Visitors Should Prepare

Accessibility information states that there is a ramp at the main entrance, an elevator for visitors with disabilities, and two accessible parking spaces, and that wheelchairs and strollers can be rented. Since visitors must move through the entire four-story building, stroller and wheelchair users should first ask at the entrance where the elevator is and whether rentals are available.

The available information does not confirm photography-restricted areas, controlled-access areas, the extent of access to exhibits behind glass walls, or whether English information and audio guides are provided. Since the 4D Theater and interactive equipment may operate differently from standard exhibitions, ask staff after purchasing a ticket whether they can explain the participation process in English.

Plan to arrive well before the 17:00 admission deadline. An efficient order is to check the first-floor aquarium and experience options, then coordinate your visit with the second-floor 4D Theater schedule. Considering a 2025 review that described the facility as not very large and reported an overall visit of about one hour, it is better suited as a stop between other activities in Jangheung-eup than as an all-day destination.
