Autumn is widely considered the most beautiful season in South Korea. From late September through November, the country transforms into a canvas of gold, amber, and crimson as the leaves change across mountains, islands, and river valleys. If you are planning a trip to Korea in the fall, these three destinations are absolutely unmissable.
Nami Island
Nami Island is one of South Korea's most iconic autumn destinations, and for good reason. This small crescent-shaped river island in Gangwon-do is famous for its long tree-lined avenues that turn into breathtaking tunnels of gold and yellow every autumn. It became internationally famous after featuring in the Korean drama Winter Sonata, and today it draws visitors from across Asia who come specifically for the fall foliage.
Autumn Season: Mid-October to mid-November
The peak of autumn colour on Nami Island typically falls between 20 October and 10 November, when the metasequoia and ginkgo trees are at their most vivid. The island is at its most magical in the early morning before the crowds arrive, with golden light filtering through the canopy of yellow leaves.
Highlights
The Metasequoia Lane is the most photographed spot on the island, a long straight avenue of towering trees that turns a deep golden-red in autumn. The Ginkgo Tree Road runs parallel and turns a brilliant yellow, carpeting the ground in fallen leaves. Beyond the famous avenues, the island has cycling paths, riverside walks, art installations, and a charming collection of cafes and restaurants. The ferry crossing from Gapyeong adds to the sense of arrival.
Getting There
Take the ITX-Cheongchun train from Seoul Cheongnyangni Station to Gapyeong Station, then a short taxi or bus ride to the ferry dock. The journey takes approximately one hour from Seoul. Nami Island pairs perfectly with a visit to Gangchon Rail Bike on the same day.
Seoraksan National Park
Seoraksan is South Korea's most celebrated national park and arguably the finest place in the country to experience autumn foliage. The dramatic granite peaks of the Taebaek Mountain Range provide a spectacular backdrop as the forests below erupt in vivid shades of red, orange, and gold. It is a destination that genuinely takes your breath away.
Autumn Season: Late September to late October
Seoraksan's autumn colour begins at the highest peaks in late September and gradually descends to the lower valleys through October. The absolute peak, when the entire mountain is ablaze with colour, typically falls between 10 October and 25 October. This is also when the park is at its busiest, so arriving early or visiting on a weekday is strongly recommended.
Highlights
The Seoraksan Cable Car (Gwongeumseong Cable Car) offers the most dramatic aerial view of the autumn foliage, lifting visitors above the treeline to a rocky fortress with panoramic views in every direction. On clear days the colours stretch as far as the eye can see. The Biryong Falls Trail is one of the most rewarding hikes in the park, passing through dense forest that turns vivid red and orange in autumn before reaching a beautiful waterfall. Sinheungsa Temple, one of Korea's oldest Buddhist temples, sits at the entrance to the park and is surrounded by ancient trees that frame the temple buildings in autumn colour. The giant bronze Buddha statue nearby is particularly atmospheric in the fall light.
Getting There
Take an express bus from Seoul Express Bus Terminal to Sokcho (approximately 2.5 hours), then a local bus or taxi to the national park entrance. Sokcho is a great base for exploring Seoraksan, with excellent seafood restaurants and accommodation options at all price points.
Gangchon Rail Bike
The Gangchon Rail Bike is one of South Korea's most unique and memorable autumn experiences. Riders pedal converted rail bikes along a decommissioned railway track that winds through the Bukhan River valley, passing through tunnels and over bridges with the autumn forest surrounding them on all sides. It is equal parts activity and scenery, and the combination makes it one of the most enjoyable things to do in Korea in the fall.
Autumn Season: Mid-October to mid-November
The rail bike route is at its most spectacular between 15 October and 15 November, when the riverside forest along the Bukhan River turns gold and red. The reflections of the autumn trees in the calm river water add an extra layer of beauty to the ride. Morning departures offer the best light and the most comfortable temperatures.
Highlights
The 4.6-kilometre route from Gimyujeong Station to Gangchon Station takes approximately 40 to 60 minutes to complete and passes through two tunnels that are illuminated with colourful LED lights, a fun contrast to the natural scenery outside. The route follows the Bukhan River the entire way, with the water on one side and forested hillsides on the other. At the end of the ride, a shuttle bus returns riders to the starting point. The nearby Gangchon area has several cafes and restaurants where you can relax after the ride, and the surrounding countryside is beautiful for a short walk.
Getting There
Take the ITX-Cheongchun train from Seoul Cheongnyangni Station to Gimyujeong Station. The journey takes approximately one hour. Gangchon Rail Bike is easily combined with a visit to Nami Island on the same day, as both are accessible from Gapyeong and Gimyujeong stations on the same train line.
Planning Your Autumn Trip
The ideal autumn itinerary combines all three destinations over two to three days. Day one works perfectly as a day trip from Seoul combining Nami Island in the morning and Gangchon Rail Bike in the afternoon, both accessible on the same train line. Day two and three can be spent in Sokcho using Seoraksan National Park as the main focus, with time to explore the coastal town and its famous seafood market.
Book the Gangchon Rail Bike in advance online, especially for weekend visits in October, as slots sell out quickly during peak autumn season. For Seoraksan, the cable car also has queues during peak weekends, so arriving at opening time (typically 9am) is the best strategy.
Stay Connected on Your Autumn Journey
Navigating train schedules, booking rail bike slots, checking foliage forecasts, and sharing your autumn photos in real time all require a reliable connection. A Korea travel eSIM activates before you land and keeps you connected from Seoul to Seoraksan without roaming charges or SIM card queues at the airport.
