Pocheon Sanjeong Lake, a 4 km lakeside trail that was once an agricultural reservoir in 1925

The 1925 reservoir and the name of Sanjeongho Lake, meaning "a well in the mountains"

Sanjeongho Lake is a reservoir built in 1925 to secure water for agriculture. Its name means "a well in the mountain," and it literally describes the terrain surrounded by peaks such as Myeongseongsan and Gwanumsan. The lake area currently guided by Pocheon Urban Corporation is 644,500㎡, and its location is around 451-3, Sanjeong-ri, Yeongbuk-myeon, Pocheon-si.

The lake, originally an irrigation facility, was designated as a national tourist site in March 1977 and changed its character into a tourist destination. Around the lake are a walking trail, boat dock, bungalow accommodations, sculpture park, playground, public restrooms, and the Pocheon Gallery, and in August 1996 Hanhwa Condo opened at the entrance to the tourist site. In other words, the current scenery of Sanjeongho Lake is the result of overlapping identities: a mountain reservoir, a base for hiking Myeongseongsan, and lakeside leisure facilities.

A 4 km, about 1 hour loop around the lake starting from Sangdong Parking Lot

For a first visit, it is clearer to set Sangdong Parking Lot at 188-4, Sanjeong-ri, Yeongbuk-myeon, Pocheon-si, Gyeonggi-do as your destination. From Sangdong Parking Lot, the usual route is to pass the Sculpture Park and then circle the lake clockwise. According to the accessible tourism guide, the full loop is 4 km and takes about 1 hour to complete. The Korea Tourism Organization's English guide also lists the trail as 3 km, so it is safer to plan around 1 hour 30 minutes including photos and breaks.

On the southwest side of the lake is Hadong Parking Lot, and at the 4 o'clock direction on the east side is Sangdong Parking Lot. Both parking lots have tourist information centers, disabled parking spaces, and accessible restrooms, and Sangdong Parking Lot also has EV charging stations. At the fork at the entrance to Sangdong Parking Lot, the left path is easier for walking without assistance, while the right path is a section where some walking assistance is recommended.

• Sangdong Parking Lot: 188-4, Sanjeong-ri, a starting point close to the Sculpture Park

• Recommended time: 4 km loop about 1 hour, 1 hour 30 minutes including breaks

Free admission and 2,000 won for a small car: separate the lake use fee from parking

Admission to Sanjeongho Lake itself is free, and there are no annual closing days or time restrictions. The Korea Tourism Organization guide lists it as open 24 hours a day, year-round. Late at night, walking is possible, but individual facilities such as the music fountain and tourist information center follow separate operating conditions.

For vehicles, parking fees apply once per day: 2,000 won for small cars, 5,000 won for medium cars, and 10,000 won for large cars. Pocheon citizens are exempt from parking fees upon presenting identification. Therefore, the information that it is a "free tourist site" refers only to admission to the lake, and visitors by private car must calculate parking fees separately.

The official information website is https://www.sjlake.co.kr, and the tourist information address for Sanjeongho Lake is also listed as 402, Sanjeongho-ro, Yeongbuk-myeon, Pocheon-si, Gyeonggi-do. Inquiries about management and facilities can be made at 031-540-6350 or 031-540-6355.

The music fountain runs from 11:00 on weekdays and 10:00 on weekends, and stops in rain or strong wind

The music fountain operates for about 25 to 30 minutes each session. On weekdays, it runs at 11:00, 13:00, 15:00, 17:00, and 19:00; on weekends and public holidays, it is scheduled to run 10 times on the hour from 10:00 to 19:00. When planning your walking route, starting from Sangdong Parking Lot and passing the Sculpture Park and the area around the music fountain can reduce waiting time.

However, this timetable is not a fixed reservation schedule for performances. It does not operate during winter or in bad weather, and it is suspended if the forecast shows a 60% or higher chance of rain or if strong winds exceed 5 m/s. Because operations are adjusted flexibly depending on energy conditions and the season, it is a good idea to call 031-540-6350 on the day you plan to visit if you are coming specifically for the fountain.

Myeongseongsan at 922.6 m and Jeungnyong Waterfall: how to decide on the next turn after a lakeside walk

Myeongseongsan behind Sanjeongho Lake is a mountain with an elevation of 922.6 m, straddling the border between Pocheon-si and Cheorwon-gun, Gangwon-do. Pocheon Urban Corporation explains that the name Myeongseongsan comes from the story that Gungye cried bitterly here after being defeated by Wang Geon. The silver grass colony on the eastern side of the southern Samgakbong ridge has also been the background for the Silver Grass Flower Festival held from late September to early October since 1997.

For travelers who want only a light visit to the lake, finishing with the 4 km loop is appropriate, while those with hiking gear and enough time should separate the Myeongseongsan course into a different schedule. Jeungnyong Waterfall, guided as the water source of Sanjeongho Lake, and Biseon Waterfall on the upper part of the lake are different in character from the flat sections of the lakeside trail, so it is better to avoid planning them as one route without sneakers and preparation for uphill walking.

Wheelchairs and strollers should first choose the left entrance road at Sangdong Parking Lot

The Sanjeongho Lake loop trail is Informationed as a barrier-free trail usable by wheelchairs throughout, but it is not completely flat. There are sloped sections near the observatory, and the route mixes wooden decks and unpaved paths, so users of manual wheelchairs are advised to have a companion's assistance. For the same reason, strollers are relatively easier to use when starting from the left entrance road at Sangdong Parking Lot.

There are five disabled parking spaces each at Sangdong and Hadong Parking Lots, and accessible restrooms are located in six places including the parking lots and the loop trail. If you enter through Sangdong Parking Lot, you can use a nursing room, and the Sculpture Park also has an accessible restroom and a baby rest area. Manual wheelchairs are available for rental from 09:00 to 18:00.

• Wheelchair rental: 09:00-18:00, manual wheelchairs
• Disabled parking: 5 spaces each at Sangdong and Hadong Parking Lots
• Accessible restrooms: 6 places including parking lots and the loop trail
• English information: Available on the Korea Tourism Organization VISITKOREA English page

About 30 km from Jeongok Station, this lake is easier to reach by car than by bus

From the perspective of railway stations, Sanjeongho Lake's Sangdong Parking Lot is about 30 km from Jeongok Station, and the drive takes about 40 minutes. Sanjeongho Lake is not a place you can reach on foot directly from a subway station in central Seoul, so you should check private car, rental car, or local Pocheon bus times before departure. Bus routes and intervals may change frequently, so it is necessary to check real-time information from Pocheon City or a map service on the day you depart.

The address provided by the user for "Galbi1987 Pocheon I-dong Main Branch" is not the official address of Sanjeongho Lake, but the separate address of a restaurant in I-dong-myeon. For lake visits, use navigation to "Sanjeongho Lake Sangdong Parking Lot (188-4, Sanjeong-ri, Yeongbuk-myeon, Pocheon-si)" or "402, Sanjeongho-ro, Yeongbuk-myeon, Pocheon-si, Gyeonggi-do" to reduce destination confusion. Sanjeongho Lake is open 24 hours, but parking lot congestion, seasonal events, and music fountain operation may vary by time of day.
