Jeju · Seogwipo, Jeju
중문색달해수욕장
Four colours of sand, real waves, and the island's surf and dive centre.
Jungmun's sand is famously mixed — black, white, red and grey grains together — and it sits under a cliff on Jeju's southern side.
The waves here are the biggest of any Jeju beach, which makes it the island's surfing and bodyboarding beach and means swimmers should watch the flags.
What else is here
Jungmun Saekdal sits below the Jungmun resort complex on Jeju's south coast. It has the biggest waves on the island, the darkest sand, and more to do within walking distance than any other beach here.
Jeju's main break
The south coast catches swell the north never sees, and Jungmun is where it lands. There are surf schools and board hire on the beach, and in autumn — when typhoons are passing well offshore — it produces the best waves in Korea.
Ten minutes away
A wall of hexagonal basalt columns dropping straight into the sea, formed as lava cooled and cracked. One of the most striking geological sights on the island and an easy walk from the resort.
Three waterfalls and a bridge
A chain of three falls in a wooded gorge just inland, crossed by the ornate Seonimgyo bridge. Flat paths and about an hour.
For better and worse
Jungmun is Jeju's planned resort district — the big international hotels, the convention centre and the golf are all here. That means good facilities and very little local character.
The south coast
Jungmun Saekdal faces south into open water, and that changes everything about it. Where the northern Jeju beaches are flat and shallow, this one has a genuine shore break — good for surfing, and worth respecting if you are swimming with children.
The sand is dark, coarse and volcanic, framed by black cliffs, with a cave in the rocks at the eastern end. It is a more dramatic beach than Hyeopjae or Hamdeok and a less relaxing one.
Everything else is within walking distance because the resort district was planned that way: the columnar cliffs at Jusangjeolli, the Cheonjeyeon waterfalls, the Yeomiji botanical garden. If you want one base on Jeju that requires no driving, this is the argument for it.
Hyeopjae Beach
White shell sand, water the colour of a swimming pool, and an island offshore.
Hamdeok Beach
Shallow, calm and close to the airport — the easy Jeju beach day.
Woljeongri Beach
A row of cafés looking straight out at very blue water.
