Meet a hidden gem for a weekend escape in Imsil, North Jeolla Province.
Okjeong Lake is a vast man-made reservoir that formed in 1965 after construction of the Seomjin River multipurpose dam. The name comes from a mid-Joseon legend in which a monk predicted the emergence of a “clear lake” (Okjeong) in this spot.
The showpiece is Carp Island, a small island seemingly floating in the middle of the lake. Viewed from Guksabong, its silhouette resembles a swimming carp, which is how it got its name. In spring and fall, when daytime and nighttime temperatures differ sharply, sheets of morning mist rising from the water create an otherworldly scene.
In spring, the lakeside road becomes a tunnel of cherry blossoms—perfect for a slow, scenic drive. This year’s festival was held on the 11th and 12th at the Okjeong Lake suspension bridge and Carp Island Ecopark, timed to peak bloom to spotlight Imsil as a top spring destination under its “Ten-Million Tourists Imsil Era” initiative.
Imsil County planted roughly 31,000 spring blooms—pansies, anemones, and daffodils—throughout the Carp Island Ecopark, and placed floral spheres and planter boxes along main paths to greet visitors.
Where to find the best cherry blossoms around Okjeong Lake
Local Route 749 snakes about 10 km from Unam Bridge to Gangjin-myeon and is celebrated as one of Korea’s “100 Most Beautiful Roads.” Cherry trees line the curves of the lake, creating a tunnel effect: one window frames blue water, the other rains down blossoms. There are pit stops and small overlooks where you can pull over, stretch your legs, and take photos with a cool lake breeze. At night, illuminated sections add a dreamy, romantic vibe.
At Carp Island Ecopark, daffodils, tulips, and spiraea bloom alongside the cherry trees for a bright, layered spring display. The 420 m suspension bridge offers striking waterfront views of the cherry blossom line from above the lake. Follow the island’s walking trails and you’ll find benches tucked beneath blossoms that invite you to pause and drink in the view.
The Guksabong observatory, near the Guksabong rest area, is the highest vantage point for sweeping views of Okjeong Lake. From here, pale pink cherry blossoms, dark-green pines, and Carp Island combine into a surreal panorama. It’s about a 15–20 minute climb up decked steps from the parking area to reach the first lookout.
Guksabong is a modest 475 m peak, but the trail from the parking lot to the summit has some steep sections. As you climb, Okjeong Lake’s S-shaped curves and the surrounding ridgelines unfold like a panorama. Reaching the second and third lookouts takes around 15–20 minutes on foot. From the summit, you get 360-degree views that include the lake and the Obongsan ridge across the way.
Admission to the Okjeong Lake suspension bridge is 4,000 KRW (3 USD) for adults; 3,000 KRW (2.25 USD) for seniors 65+ and people with mild disabilities; 2,000 KRW (1.50 USD) for elementary, middle, and high school students; and 1,000 KRW (0.75 USD) for Imsil County residents. (Summer operating hours are 9:00 AM–6:00 PM, with last entry at 5:00 PM.)
Parking is free. By public transit, take the Imsil–Gwanchon–Unam or Imsil–Unam–Gangjin bus from Imsil Station, get off at the Ipseok stop, and walk about 14 minutes to reach the site.
