Seoul and Busan headline nearly every South Korea itinerary, and for good reason. But travelers who venture past the two big names often find the trips they remember most. The country's southern and eastern coastlines are lined with port towns, island views, cliff-top temples and traditional markets that see a fraction of the crowds.
This guide from Gohub rounds up four of the best hidden gems in South Korea: Tongyeong, Namhae, Sokcho and Yeosu. Each one pairs slower-paced sightseeing with fresh seafood and coastal scenery, and each is easy to reach once the main cities are ticked off. Below, you’ll find what makes each destination worth visiting, who it suits and what to know before adding it to your route.
The big cities are unmissable, but they are also where most international visitors concentrate. Stepping out to smaller coastal destinations changes the trip in a few ways. Prices for food and stays tend to be gentler, popular sights feel calmer outside weekends and holidays, and the scenery shifts from skylines to seascapes.
These towns also show a different side of Korean daily life, from working harbors to family-run seafood restaurants and markets that have traded for centuries. For anyone who has already seen the palaces and shopping districts, this is where a second trip to Korea earns its keep.
A quick note before diving in: crowd levels vary by season. All four destinations can get busy on weekends, public holidays and during the peak summer and autumn travel periods, so midweek visits reward travelers with the quietest experience.
Sitting on the south coast of Gyeongsangnam Province, Tongyeong is a picturesque port city often nicknamed the "Naples of Korea" for its harbor setting and scatter of nearby islands. It makes an easy addition to any trip that already includes Busan, roughly two hours away by road.

The signature experience is the 1,975-meter Tongyeong Cable Car, which climbs toward the upper slopes of Mireuksan Mountain in around nine minutes. From the top, the view opens across the Hallyeohaesang seascape, a maze of green islands drifting across the bay and the highlight of Hallyeohaesang National Park.
Back at sea level, Jungang Traditional Market is the place to slow down. Jungang Traditional Market is one of the city’s best-known places for fresh seafood, dried fish, local snacks, and everyday market life. Tongyeong is also known for its oyster harvests, so a seafood lunch here is close to mandatory. Travelers with extra time can hop a short ferry to one of the surrounding islands for even quieter coastal walks.
Good for: Coastal panoramas, seafood lovers, first-time visitors to Korea's south coast.
Suggested stay: 1–2 nights
Best reached from: Busan by intercity bus
When to go: Spring or autumn for comfortable weather and clear coastal views
Getting around: Local buses and taxis connect the main attractions. A rental car is useful for exploring quieter coastal areas outside the city center.
Namhae is a scenic island county connected to the mainland by a series of bridges, which makes it far easier to reach than its remote feel suggests. It is one of Korea's larger southern islands and is best known for dramatic coastal drives, terraced fields and peaceful fishing villages.

Three sights anchor most visits. Gacheon Daraengi Village is famous for its steep rice terraces that step down the hillside toward the sea, one of the most photographed rural landscapes in the country. Namhae German Village, built by Korean workers who returned from Germany, brings an unexpected European streetscape and cafés overlooking the bay. And Boriam Hermitage on Geumsan Mountain rewards a short hike with sweeping views out over the water.
Namhae is more about scenery and stillness than checklist attractions, which is exactly its appeal. A rental car or organized day tour makes it easy to link the island's spread-out highlights in a single day.
Good for: Road trips, photography, travelers chasing quiet countryside views.
Suggested stay: 1–2 nights
Best reached from: Busan, Jinju or Yeosu by intercity bus, followed by local transport
When to go: Spring for green landscapes and flowers, or autumn for mild weather
Getting around: Namhae’s attractions are spread across the island, so a rental car or organized tour is the most convenient option. Public buses are available but may run infrequently.
Up on the northeastern coast, Sokcho is the go-to base for exploring Seoraksan National Park, home to some of South Korea's most dramatic mountain scenery. Granite peaks, forested valleys and temples make it a favorite for hikers, and the trails run from gentle walks to serious summit climbs.

Sokcho itself is a rewarding stop even for non-hikers. Daepo Port is the spot for fresh seafood pulled straight from the boats, and the city's beaches and markets offer an easy, low-key day by the water. The contrast of mountains on one side and the East Sea on the other is what makes Sokcho stand out.
Autumn is the marquee season here, when Seoraksan's foliage turns, though that also makes it the busiest. Travelers who prefer space to breathe should aim for a weekday visit.
Good for: Hikers, nature lovers, anyone combining mountains and coast in one trip.
Suggested stay: 2 nights
Best reached from: Seoul by express or intercity bus
When to go: Spring for hiking, summer for the coast, or autumn for Seoraksan’s foliage
Getting around: Local buses connect central Sokcho with Seoraksan National Park and other major attractions. Taxis are convenient for shorter trips around the city.
On the southern coast, Yeosu is a port city known for its scatter of islands and a waterfront that comes alive after dark. Once host to a World Expo, the city has an easygoing seaside energy and some of the best sunset-to-night views on this list.

The clifftop Hyangiram Hermitage is the standout, a small temple perched on a rocky hillside above the sea and especially popular at sunrise. The Yeosu Maritime Cable Car offers another vantage point, carrying passengers over the water between the mainland and Dolsan Island. As evening falls, the illuminated bridges and harbor make the waterfront a natural place to end the day.
Yeosu also connects well by train, making it one of the more accessible destinations on this list for travelers based farther north.
Good for: Night views, temple settings, relaxed coastal evenings.
Suggested stay: 1–2 nights
Best reached from: Seoul by train to Yeosu-Expo Station, or from Busan by intercity bus
When to go: Spring or autumn for pleasant coastal weather; early spring is also popular for camellias on Odongdo Island
Getting around: City buses and taxis cover the main waterfront attractions. A rental car is helpful for visiting Hyangiram Hermitage and more distant parts of Dolsan Island.

Tongyeong, Namhae, Sokcho and Yeosu are four of the most rewarding. They offer a change of pace from Korea’s largest cities, although popular attractions can still become busy on weekends and during peak seasons.
Spring and autumn bring the most comfortable weather and the best scenery, especially around Seoraksan National Park near Sokcho. Weekdays outside public holidays and peak summer are quietest.
Yeosu has the most convenient rail connection, including trains from Seoul. Tongyeong and Sokcho are commonly reached by intercity or express bus, while Namhae is easiest to explore by rental car or organized tour. Always check current schedules before traveling.
