If you’re looking for a place near Seoul where you can enjoy autumn scenery and give your kids a taste of nature, Siheung Gaetgol Ecological Park is an easy one to add to your plans.
It’s more than a walking park. Traces of the old Sorae salt pans, tidal-channel wetlands and salt warehouses remain here, and you can enjoy a swaying observation tower and a salt-making experience too.
October is an especially good time to go, when the wide meadows, reeds and silver grass come together for a classic autumn outing.
Here’s everything based on 2026 operating information, from parking to kid-friendly activities and a recommended route.
1. Siheung Gaetgol Ecological Park Parking and Basic Information
Siheung Gaetgol Ecological Park is located at 287 Dongseo-ro, Siheung-si, Gyeonggi-do.
The park itself is open 24 hours and admission is free, but the information center is open only from 9 a.m. to 6 p.m. If you want to do the paid activities, plan your visit around program hours rather than park hours.
- Address: 287 Dongseo-ro, Siheung-si, Gyeonggi-do
- Park hours: 24 hours, open year-round
- Admission: free
- Information center: 09:00–18:00
- Phone: +82-31-488-6900
The parking lot holds 284 vehicles (266 regular and 18 large).
According to registered tourism information, parking is charged from 9 a.m. to 6 p.m.: 1,400 KRW for 1 hour, 2,800 KRW for 2 hours, 4,200 KRW for 3 hours and 5,600 KRW for 4 hours. It’s free outside those hours. Rates can change, so if you’re staying a long time, check the sign at the entrance.
The lot can get crowded on weekends and during events; Siheung Urban Corporation also warns that spaces may run short in peak season, on weekends and during festivals.
2. In Autumn, Start With the Swaying Observatory
The signature landmark of Siheung Gaetgol Ecological Park is the Swaying Observatory (Heundeul Jeonmangdae).
It’s a six-story wooden tower, 22 meters tall, designed — just as the name says — to move slightly in the wind. From the top you get a sweeping view of the tidal channels, meadows and the whole park.
In autumn, the tall grasses around the tower make for great compositions. Rather than shooting the tower alone, put the trail and silver grass in the foreground to capture the feel of the place.
Kids tend to love the tower itself. It gets higher as you climb and you can feel a slight sway, which makes it more fun than an ordinary viewpoint.
Note that it’s stairs-only with no elevator, so you can’t take a stroller up.
3. The Salt Pans and Salt Warehouses You’ll Miss If You Think It’s “Just a Park”
When visiting Siheung Gaetgol Ecological Park with kids, don’t just see the observatory and leave — visit the salt pan experience area and salt warehouses too.
This area was once home to the Sorae salt pans. The current ecological park was created from abandoned salt fields and an inner-bay tidal channel, and Siheung Gaetgol was designated a Marine Wetland Protected Area in 2012.
Restored salt pans and salt warehouses still stand inside the park.
It’s a great spot to explain to kids how salt was made from tidal flats. The trip goes beyond scenery to connect nature with the history of a local industry — that’s what makes this place special.
4. Check the Activity Programs Before You Go
In 2026, Siheung Gaetgol Ecological Park runs a salt-pan experience, multi-seat bicycles, water bikes and an electric-cart tour. Each program runs on different days, so if you just show up you might miss the one you wanted.
- Salt-pan experience: April–October, 5,600 KRW, 40 minutes, ages 36 months and up
- Multi-seat bicycle: April–November, 14,000 KRW, 30 minutes, minors must ride with a guardian
- Water bike: April–October, 14,000 KRW, 30 minutes, 140 cm and taller
- Electric-cart tour: March–November, 2,800 KRW, 15 minutes, first-come, first-served on site
For individual participants, the salt-pan experience runs at 2, 3 and 4 p.m. on weekends and public holidays, with first-come registration at the information center from 9:30 a.m. It takes a break in July and August and then resumes, so if you visit with kids in October, it should be high on your list.
On the other hand, the electric-cart tour does not run on weekends or public holidays. It operates mainly Tuesday to Thursday and on Friday mornings, and you can’t get off midway. Weekend visitors shouldn’t build their plans around it.
There’s also a free Eco Imagination Playground, so if you have little ones, add it to your route along with the observatory and salt pans.
5. An Easy Route With Kids
Siheung Gaetgol Ecological Park covers about 1.5 million square meters, so trying to walk every section takes longer than you’d expect. With young children, it’s better to pick the key areas.
Parking lot → Information center → Lawn plaza → Salt-pan experience area and salt warehouses → Swaying Observatory → Eco Imagination Playground → Parking lot
That’s a realistic plan for a family day out.
Allow about 2 hours if you focus on walking and the observatory, or 3–4 hours if you add the playground and the salt-pan experience or bikes. These are my estimates for traveling with kids, not official visit times.
If you bring a picnic mat, a rest on the lawn plaza is lovely. However, cooking isn’t allowed anywhere in the park except the designated cooking zone. In 2026 the cooking zone operates March–October and is closed on Mondays and Tuesdays.
Nearby Siheung Spots to Combine
If you want to add some history, Oido Prehistoric Site Park is a good choice. Remains from many eras, starting with prehistoric shell mounds, have been found at the Oido site, and the park lets you enjoy nature and history together.
To add more learning, pair it with the Marine Ecology Science Museum. In 2026 it’s open 10:00–18:00 and closed on Mondays; admission is 8,000 KRW for adults, 6,000 KRW for teens and 4,000 KRW for children. It’s indoors, so it’s handy on days with uncertain weather.
To finish the day with a sunset, I recommend Baegot Hanul Park. It stretches along the west coast and offers a very different seaside view from the tidal-channel park.
Siheung Gaetgol Ecological Park isn’t about one particular autumn flower — its strength is combining tidal wetlands, silver grass scenery, an observatory, salt-making culture and kids’ activities in one trip.
If you’re going with elementary schoolers, try to include the salt-pan experience. For families looking for a half-day nature trip near Seoul, it’s well worth adding to your autumn plans.
