Perched like a volcanic gem in the Korea Strait, Jeju Island is the largest island in South Korea. The island, known for its subtropical climate, is cloaked by Hallasan Mountain and experiences mild winters and warm summers with intermittent rainfall all year round. Scattered across the island are unique ecosystems formed by lava tubes, waterfalls, and striking coastal structures.

A significant distinction of the island lies in its culture, which greatly differs from mainland Korea. This is primarily because of its matriarchal society and the fascinating haenyeo - female divers who have harvested seafood for generations. These women, most of whom are now in their 60s and 70s, represent a dying way of life that has been commemorated by UNESCO.

The charm of Jeju Island lies in the blend of natural wonders and cultural heritage it offers. The tourist hotspot is home to three UNESCO World Heritage sites: Hallasan Mountain, the Geomunoreum lava tube system, and Seongsan Ilchulbong, an impressive tuff cone created by a volcanic eruption. As for local cuisine, it revolves around fresh seafood, black pork (a regional speciality), and unique ingredients such as hallabong citrus.

Remember to pencil in a hike to Hallasan, the tallest peak in South Korea, where you can experience crater lakes and breathtaking views. The Olle Trail system, which includes 26 routes circling the island, is perfect for exploring coastal villages and hidden beaches. To immerse yourself in the island's unique architecture and customs, a visit to the Jeju Folk Village is highly recommended.
