Yongduam, or Dragon Head Rock, is a volcanic rock formation on the coast near Jeju City. Shaped by waves, it is said to resemble the head of a dragon rising from the sea. A short walkway leads along the shore for the best views. It is close to Jeju airport, making it a convenient first or last stop on the island, and lovely at sunset.

Manjanggul is one of the longest lava tubes in the world, formed by flowing lava thousands of years ago. About one kilometre of the tunnel is open to visitors, ending at a lava column about seven metres high. The cave is cool and damp all year, so bring a light jacket and good shoes. It is part of the UNESCO-listed Jeju Volcanic Island and Lava Tubes.

Seongsan Ilchulbong, or Sunrise Peak, is a volcanic tuff cone that rises from the sea on the eastern tip of Jeju. A steep trail climbs to the rim of its crater, where the sunrise over the ocean is famous. It is part of the UNESCO-listed Jeju Volcanic Island and Lava Tubes. Haenyeo women divers often demonstrate their traditional diving at the base.

Jeongbang Falls is a waterfall on the southern coast of Jeju that drops straight into the sea, one of the few of its kind in Asia. Visitors take a stairway down to the rocky shore at its base. Legend says an envoy sent to find the elixir of life left an inscription here. It is close to the centre of Seogwipo and easy to combine with Cheonjiyeon Falls.

Jusangjeolli Cliff is a stretch of coastline in Seogwipo lined with tall basalt columns formed when lava cooled quickly as it met the sea. Waves crash dramatically against the hexagonal pillars. A wooden walkway and viewpoints run along the top of the cliffs. It is part of the Jeju Global Geopark and is especially impressive on days with strong surf.

Hyeopjae Beach on Jeju's west coast is known for its white sand mixed with shell fragments and its shallow, emerald-coloured water. Across the bay lies the small island of Biyangdo, which gives the beach its famous view. A pine grove behind the beach offers shade. The beach is ideal for families and especially beautiful at sunset.

Hallasan is the highest mountain in South Korea, a shield volcano at the centre of Jeju Island. The Seongpanak Trail is the longest route to the summit crater lake, Baengnokdam, and takes most of a day. Hikers must reserve in advance and pass checkpoints before set cut-off times. The trail passes through forests and a shelter with views across the island.
