Jeju Ttukbaegi

Seongsan Ilchulbong Tuff Cone

Two separate walks share the site: a ticketed climb to the summit, 30–40 minutes of stairs, and a free coastal path around Umutgae with a much gentler gradient. The monthly closure is the thing that ruins trips — it is the first Monday, not a holiday pattern anyone guesses.

Seopjikoji

A headland running out into the sea on Jeju's eastern coast. Koji is the Jeju word for a cape; for Seopji the publisher records two readings side by side — that it describes ground said to produce men of talent, and that it comes from hyeopji, meaning narrow land. The path crosses hills of red volcanic scoria and follows low rock cliffs, and a Joseon-period beacon mound stands on the open grassland. What sets it apart from Jeju's other coastal walks is that Seongsan Ilchulbong stands in the background for most of the way round, which is why it photographs the way it does.
