Gobok Nature Reservoir Park

Designated as Sejong's sole official Natural Park in 1990, Gobok Nature Reservoir Park covers 1.94 million square meters surrounding the pristine Yongam Reservoir in Yeonseo-myeon. Originally engineered in the 1960s to supply agricultural water to the surrounding orchards, the area was redeveloped into an eco-friendly ecological sanctuary that protects rich wetland habitats while offering tranquil waterside leisure to travelers.

The park features a modern 3.5-kilometer elevated wooden boardwalk known as the Suyeon Eco-Trail, which skims gently above the lake's shimmering surface under weeping willows and alder groves. Along the loop, visitors discover an open-air sculpture park, the Lotus Blossom Observation Marsh, shaded waterside pergolas, children's ecological playgrounds, and cantilevered fishing observation piers.

Spring is celebrated with the vibrant Yeonseo Cherry Blossom Festival, when thousands of king cherry trees form a 4-kilometer continuous pink canopy looping around the reservoir road. Summer blankets the upper coves in white water lilies and lush green reeds. Autumn turns the surrounding forest hills into brilliant shades of crimson oak and amber chestnut, while serene winter mornings bring migrating wild waterfowl across calm ice-edged waters.

The reservoir boardwalk and public parklands remain open 24 hours daily with free access. Soft LED ambient lighting lines the entire wooden water boardwalk from sundown until 22:00 every evening, creating a romantic nocturnal strolling route. The most photogenic visiting window is late afternoon around 16:30, letting you enjoy serene birdwatching followed by sunset glowing across the water.

Entry to Gobok Nature Reservoir Park, its sculpture meadows, and the aquatic boardwalk trail is completely free of charge. Complimentary public parking lots are spaced conveniently along Dosingobok-ro, adjacent to the Minrakjeong pavilion and the sculpture park.

The 3.5-kilometer Suyeon Eco-Trail is built with level wooden decking, broad wheelchair turnaround platforms, and non-slip textured surfaces. The trail is fully accessible for baby strollers and wheelchairs without step barriers. Accessible public restrooms and shaded resting shelters are located at the main parking plazas and near the outdoor sculpture garden.

Recommended 2-Hour Lakeside Leisure Route: Start at Minrakjeong Pavilion parking area → walk out onto the floating wooden Suyeon Eco-Trail → pause at the water lotus observation deck → explore the outdoor sculpture park featuring works by contemporary Korean sculptors → stroll along the pine-shaded bank to the southern wetland weir → conclude with a meal at the famous Gobok duck & spicy catfish food street.

Gobok Reservoir is celebrated throughout the Chungcheong region for its signature culinary village: indulge in piping-hot Spicy Catfish Stew (Megi Maeuntang) boiled with hand-torn dough flakes and fresh aromatic water celery, herbal Braised Duck Stew (Ori Baeksook) simmered with medicinal roots, and savory char-grilled spicy chicken.

Vegetarian travelers can savor rustic countryside specialties at lakeside family restaurants: seasoned wild acorn jelly salad (dotori-muk muchim), golden pan-fried potato pancakes (gamjajeon), and buckwheat noodles served with fresh regional mountain herbs. Waterfront lifestyle cafes surrounding the lake serve artisanal pour-over coffees and sweet sweet-potato pies.

To protect native freshwater fish and migratory bird sanctuaries, motorized personal watercraft and swimming are strictly forbidden throughout the reservoir. Fishing is permitted only within designated eco-angling zones with barbless hooks. Camping, open wood fires, and littering are strictly prohibited. Leashed pets are welcomed on the boardwalk.

Safety ring buoys and CCTV emergency call poles are stationed every 200 meters along the water deck. Lifeguards and municipal safety rangers patrol the shoreline daily.
