Sanmagi Yet-gil in Goesan is a quiet lakeside walk where the forest stays close on one side and Goesanho Lake opens up on the other. The route follows an old path once used by residents traveling between Oesa-ri and Sanmagi Village, so it feels more like a restored village road than a purpose-built city promenade.
The main trail is 3.93 kilometers long. Most visitors can enjoy it without technical hiking gear, but the uneven ground, steps and gentle rises make comfortable walking shoes a better choice than sandals. A one-way walk followed by a sightseeing boat can be a pleasant option when boats are operating, while an out-and-back walk gives you more control over your schedule.

Why This Goesan Lake Trail Feels Different
The name Yet-gil means “old road.” Rather than cutting a new line through the landscape, the restored route follows the contour of an earlier path used by local residents. Eco-friendly restoration kept much of the forest character intact, and long stretches still feel closely tied to the hillside.
You will alternate between shaded woodland, wooden walkways, rocky edges and open lake viewpoints. The trail is not difficult in the way a mountain summit route is, but it is not completely flat or barrier-free. Roots, steps and narrow sections require attention, particularly after rain.
Goesanho Lake Views Along the Walk
The lake is the reason to take this walk slowly. Through gaps in the trees, you can see long folds of water framed by low mountains. In calm weather the slopes reflect clearly, while mist gives the valley a softer, quieter look.
Morning is good for a cooler walk and fewer people. Later in the day, the lower light can bring out the shape of the hills, although the direction of the sun varies by season and by viewpoint. Instead of waiting for one famous photo spot, watch for openings in the trees as the path bends around the shoreline.
The best views do not always appear at the widest platform. Use tree trunks or railings as foreground elements, and step aside before taking a photo so you do not block the narrow trail.
Trail Difficulty and Route Choices
For regular walkers, the main Sanmagi Yet-gil route is generally easy to moderate. The distance is manageable, but the natural surface and repeated small changes in elevation can be tiring for young children, older visitors or anyone expecting a level boardwalk.
Walk from the entrance to a few nearby viewpoints, then return the same way.
Classic one-way walk
Follow the 3.93 km old trail to Sanmagi Village and return by boat only if service is confirmed.
Independent plan
Walk out and back. This takes longer, but it avoids relying on a boat timetable.
Extended hike
Add a nearby mountain route only if you have a proper trail map, enough daylight and suitable footwear.
Allow about 1.5 to 2 hours for the one-way trail if you stop for photos. Fast walkers may need less, while families and photographers should leave more time. Start early enough to return before dark if you are not certain about the boat service.
Small Bridges and Forest Viewpoints
The walk includes several playful structures and named scenic stops. A short suspension bridge between pine trees is one of the most memorable, but it is only a small part of the route. The surrounding forest, rocky shoreline and changing perspective across the water are more rewarding than rushing from one signposted attraction to the next.
Some structures can sway, and wet wooden surfaces may be slippery. Keep children close, give other walkers room and follow any closure signs posted on site.
Sanmagi Village and the Boat Return
Sanmagi Village marks the far end of the classic old-trail walk. Depending on the day and season, small businesses or rest areas may be open, but do not assume every facility will operate when you arrive. Carry water and a light snack from the start.
Sightseeing boats may connect the village area with the main entrance side of the lake. Returning by water gives you a wider view of the shoreline you have just walked and saves you from retracing the entire route. It is an appealing plan, but service can change with weather, water conditions, season and passenger demand.
Confirm the departure point, last sailing and current fare on site before starting a one-way walk. If service is unavailable, be prepared to walk back.
Admission, Parking and Facilities
Official tourism information lists the old trail as open year-round and confirms that parking is available. It does not provide a current parking price or a fixed daily opening timetable for the trail itself, so check the rate displayed at the parking area rather than relying on an old blog post.

The trail itself is an outdoor walking route, not a staffed attraction with a guaranteed closing bell. That makes daylight planning important. Temporary access restrictions can still occur because of heavy rain, snow, wind, maintenance or wildfire risk.
Best Time to Visit Sanmagi Yet-gil
Spring
Fresh leaves and mild temperatures make spring comfortable for a full walk. After rain, however, shaded surfaces can remain damp longer than expected.
Summer
The forest provides useful shade, but humidity can be high. Start in the morning, carry water and check the forecast for heavy rain.
Autumn
Autumn is the most popular season because the foliage frames the lake beautifully. Weekends can be busy, so an early start gives you a quieter path and more parking choice.
Winter
Bare trees reveal wider lake views, but ice and snow can make wooden decks, steps and shaded bends hazardous. Boat service may also be limited. Treat winter as a walking visit only after checking local conditions.
Visit on a dry spring or autumn morning. You will have cooler walking weather, clearer lake views and enough daylight to change plans if the boat is not running.
Is the Trail Good for Families?
Families with children who are comfortable walking several kilometers can enjoy Sanmagi Yet-gil. The lake, forest features and small bridges add variety, so the route rarely feels monotonous. Younger children should stay close on narrow or elevated sections.
The full trail is not ideal for strollers or wheelchairs because of steps, uneven surfaces and changes in width. Visitors who need a level route can still enjoy the entrance area and nearby views, but should not assume the complete 3.93-kilometer course is accessible.
How to Get There Without a Car
Driving is the simplest option because Sanmagi Yet-gil lies outside central Goesan and rural bus departures can be infrequent. If you travel by public transport, first reach Goesan-eup by intercity bus, then check a current route to the trail in Naver Map or KakaoMap.
A taxi from the town area may be more practical when local-bus timing does not match your walk. Before entering the trail, arrange how you will return; taxis may not wait near the far end, and mobile reception can vary in mountain areas.
Easy First-Time Sanmagi Yet-gil Route
Check the weather, parking notice and boat board before setting out.
2. Forest entrance
Settle into a comfortable pace and use the restroom before the quieter section.
3. Lakeside old trail
Follow the main path, stopping where the trees open toward Goesanho Lake.
4. Sanmagi Village
Rest and decide whether confirmed boat service fits your return plan.
5. Return
Take the boat only after confirming service, or walk back with enough daylight.
Sanmagi Yet-gil and Sanmagi Lake Trail Are Not the Same
Goesan tourism information lists Sanmagi Yet-gil and the newer Sanmagi Lake Trail as separate attractions. Their entrances, access rules and seasonal conditions can differ. This guide covers the classic 3.93-kilometer Sanmagi Old Trail, so do not apply a timetable found for the newer lake trail to this route.
If you want to combine both, check the latest Goesan tourism notice first and allow extra time. Dam-area controls, maintenance or winter conditions may affect the newer route independently.
What to Bring
Comfortable walking shoes
Water and a light snack
Sun protection in warm weather
A light rain or wind layer
Insect repellent in summer
Naver Map or KakaoMap
Enough battery for navigation and calls
Expect slippery wood, mud and damp leaves. Slow down on steps and bridges, and postpone the walk if heavy rain or strong wind is forecast.

The classic Sanmagi Old Trail is 3.93 kilometers long and connects the Oesa-ri side with Sanmagi Village.
How much time should I allow?
Allow about 1.5 to 2 hours for a relaxed one-way walk. Add waiting time for a boat, or considerably more time if you plan to walk back.
Is Sanmagi Yet-gil open all year?
Current official tourism information lists no regular holiday and describes the trail as open year-round. Weather, maintenance and safety conditions can still cause temporary restrictions.
Can I return by boat?
Boat return may be available from the village area, but departures and fares are variable. Confirm service on site before committing to a one-way route.

Final Advice
Sanmagi Yet-gil is most enjoyable when the walk itself is the plan. Leave room to pause beside the lake, listen to the forest and turn back if the weather changes. The optional boat is a bonus, not something you should depend on without checking.
For a first visit, arrive in the morning, walk toward Sanmagi Village at an unhurried pace and decide on the return only after seeing the current boat notice. That simple approach avoids most timing problems and lets the Goesanho scenery remain the focus of the day.
