Saeyeongyo Bridge

Oedolgae Sea Stack

A rock pillar about twenty metres high standing alone off the Seogwipo shore, left behind when the softer rock around it wore away; pines grow on top of it. Jeju Olle Trail Course 7 passes here and continues along the coast, so it works naturally as the first or last stop of a walking day rather than as somewhere to drive to and leave. Two stories attach to it: one in which General Choe Yeong of late Goryeo dressed the rock as a commander to frighten off an enemy, and one about an old woman who turned to stone waiting for her husband to come back from the sea.

Jeongbang Waterfall

Buy a ticket at the entrance and walk down about five minutes of pine-lined steps — there is no way to see the fall from the top. Sonammeori, on the cliff above it, is a Jeju April 3 site where detainees were summarily executed; the setting is a beauty spot and a killing ground at once.

Hallasan National Park

Choose the trail before planning transport: only Seongpanak (9.6 km) and Gwaneumsa (8.7 km) reach the summit, both need an advance reservation, and both turn walkers back at a mid-mountain control point if they arrive after the cut-off. Every other trail is a half-day walk with no summit at the end of it.

Yongmeori Coast

A sea cliff where the foot of Sanbangsan runs out into the water, named for its likeness to a dragon's head going under. Volcanic debris from three craters offshore piled up here and the waves cut it into layered, curving rock. In front of the cliff — about 700 m long and 25 to 40 m high — a flat wave-cut platform carries the walking route. The monument to Hamel's shipwreck, put up in 1980, stands nearby. What governs a visit is not the posted timetable but the tide on the day: at high water or in heavy swell the route is closed outright.
