Probably the most famous island of Korea, Jeju. This island is known as the ‘Hawaii of Korea’, with its volcanic landscapes, waterfalls and beaches.
At the center of the island stands Hallasan, the highest mountain in the country, offering hiking trails with rewarding panoramic views. Along the coast, you will find unique lava tube caves and striking rock formations shaped by ancient eruptions. Waterfalls such as Cheonjiyeon and Jeongbang add to the island’s natural appeal, with some flowing directly into the ocean.
Jeju is especially suited for first-time visitors and those who enjoy road trips, as the island is best explored by car. Renting a car will allow you to move freely between its many natural attractions and hidden spots.

Located near Chuncheon, Nami Island is known for its picturesque landscapes and seasonal charm. The island became widely popular after appearing in Korean dramas, and it continues to attract visitors with its tree-lined avenues that transform beautifully throughout the year, especially during autumn when the leaves turn a vibrant yellow.
Visitors can enjoy peaceful walks along the riverside, rent bicycles to explore at their own pace, and discover small art installations scattered across the island. Cozy cafés and quiet corners make it an ideal place to slow down and take in the surroundings. It is particularly popular among couples and photographers. A little tip: try to visit this island in the morning to avoid larger crowds.

One of the best ways to experience Udo is by cycling or riding a scooter around the island, allowing you to stop at scenic viewpoints and quiet beaches along the way. The island is also known for its local specialty, peanut ice cream, which has become a must-try for visitors. Udo is ideal for travelers who prefer a slower pace and want to enjoy nature without the crowds often found on the mainland.

Situated near Busan, Geoje Island is known for its dramatic coastline and tranquil atmosphere. The island offers sweeping ocean views, particularly from locations like Windy Hill, where the landscape opens up to reveal the sea stretching endlessly into the distance.

One of its highlights is Oedo Botania, a beautifully maintained marine garden that combines natural beauty with carefully designed landscapes. The island is well suited for road trips and travelers looking to go beyond the typical tourist destinations.
Ganghwa Island Where History Meets Nature
Located just outside Seoul, Ganghwa Island is one of the most accessible islands in the country, yet it remains relatively overlooked. The island is rich in history, with ancient dolmens that are recognized as a UNESCO World Heritage site, offering insight into Korea’s prehistoric past.
Beyond its historical significance, Ganghwa also features peaceful countryside landscapes, rice fields, and coastal viewpoints that are especially beautiful at sunset. Its proximity to Seoul makes it an excellent choice for a day trip, particularly for those who want to escape the city without traveling far.
From the iconic landscapes of Jeju Island to the quiet charm of Ganghwa Island, South Korea’s islands offer something for every kind of traveler.
