The Northwestern Beach of Muuido Where Silmido and a Sandbar Meet

A place where a crescent-shaped white-sand beach stretches about 2 km northwest of Muuido Island

Silmi-do Beach is located on the northwestern coast of Muuido Island, where a crescent-shaped white-sand beach stretches for about 2 km. A beautiful forest of century-old Korean pine trees runs along the beach, creating deep shade even in the middle of the day.

Silmi-do Island can be seen nearby to the west. An amusement area has been developed around the beach, with restaurants and cafés, making it possible to plan an outing that takes in the beach, forest, and island scenery all at once rather than focusing only on water activities.

Understanding both the name Silmi-do and the traces of Unit 684

The name ‘Silmi Beach’ was given because it is connected to Silmi-do Island. Silmi-do is an uninhabited island belonging to Muuido Island, with a total area of approximately 0.26 km². A 80-meter-high hill stands in the center of the island, and its coastline is about 6 km long.

In the 1960s, the Korean Central Intelligence Agency secretly trained Unit 684 on Silmi-do for missions in North Korea. The film <Silmido>, released in late 2003, dealt with this tragic true story. The island is also known as a filming location for the drama <Stairway to Heaven>, but the film set has since been dismantled and no longer remains.

The tide determines the sandy path to Silmi-do, which appears twice a day

Between Silmi-do Island and the beach, a broad sandy flat is revealed twice a day when the sea recedes. At low tide, visitors can walk along this sandy path to Silmi-do. Official tourism information states that the walk takes about 10 minutes.

Tide times change every day, so low and high tide times must be coordinated with your itinerary. If you enter Silmi-do, you should prepare to return to the beach at least one hour before the tide comes in; otherwise, you may become stranded on the island. Experiences such as catching whelks and sea snails on the tidal flats are also available.

Tidal-flat activities and tent camping are charged separately

Silmi Beach offers tidal-flat experience programs. As of August 2026, the listed fees are 10,000 won for adults and 6,000 won for youths. The operating days, available times, and whether equipment is provided have not been separately confirmed, so do not assume that an experience session is guaranteed merely because the tide is out.

Tent camping is listed at 5,000 won for one day and 10,000 won for one night and two days. The area is known for camping and car camping. Silmi-do Naturally Formed Amusement Area is described as having a convenience store, shower facilities, restrooms, and a recycling station, but the operating status and usage fees of the showers have not been confirmed.

• Tidal-flat experience, adults: 10,000 won
• Tidal-flat experience, youths: 6,000 won
• One-day tent camping: 5,000 won
• One night and two days of tent camping: 10,000 won

Access by crossing Muuidaegyo Bridge from Incheon Airport Terminal 1 Station

Travelers using public transportation can use Incheon Airport Terminal 1 Station on the Airport Railroad as their starting point. Official tourism articles state that Muuido Island can be reached in about 30 minutes by taking a local village bus from the station, and that vehicles can access Muuido via Muuidaegyo Bridge, which opened in 2019.

However, the exact bus route number, stop, and service interval for reaching Silmi Beach have not been confirmed. Incheon City materials record that the terminal of Route 222 was changed to Keunmuri Ferry Terminal, the terminal of Jung-gu 2-1 was changed to Geojampo Hoe Center, and Route Muu 1 does not operate to Silmi Beach. Therefore, rather than departing directly from the airport, check the destination stop using the latest bus information.

• Starting point: Incheon Airport Terminal 1 Station on the Airport Railroad
• To Muuido Island: About 30 minutes by local village bus
• Vehicle access: Via Muuidaegyo Bridge
• Some past reviews mention taking Routes 222 and 2-1 from Gate 7 on the third floor of Incheon International Airport, but this information dates from 2015.
• Current bus schedules are highly subject to change.

Prepare based on paid parking and indoor restrooms

There is a parking lot, but it is paid. Parking fees differ between official pages, and the current amount has not been confirmed, so it is best not to calculate the parking fee as the same cost as the 2,000-won admission fee.

The restrooms are separated by gender and located inside a building. Official tourism information states that the access route is level and threshold-free and that wheelchairs can pass through the main entrance, but other tourism information indicates a step at the main entrance, so the accessibility information is inconsistent.

• Parking: Available, paid
• Restrooms: Available, separated by gender, inside the building
• Guide dogs: Allowed
• Pets: Allowed when accompanied by a leash and plastic bags for handling waste
• Foreign-language information service: Unavailable

Which is better: a one- to two-hour visit or overnight camping?

A 2024 review describes the combined sightseeing and activity time as approximately one to two hours. For a short visit, the key sequence is to see the pine forest and white-sand beach, then walk back and forth along the sandy path to Silmi-do according to the low tide. Because the round trip is possible only when the tide is suitable, determine the low tide time before deciding on your arrival time.

For those planning car camping or tent camping, the beach shade and the amusement area's auxiliary facilities are advantages. However, uncertain bus schedules and the lack of foreign-language information services may be drawbacks. Travelers who require English guidance, have difficulty calculating the time of the incoming tide, or find walking on sand and tidal flats challenging are advised to limit their visit to a brief beach sightseeing trip.
