장봉도

Jangbongdo is a small island in the West Sea off Incheon, accessible by ferry from Samsanhang Port. The island offers wide tidal flats (one of the strongest mudflat ecosystems in the Incheon area), a long sandy beach (Hanagae Beach), pine forest walking paths, and quiet rural hamlets. For travelers based in Seoul or Incheon who want a low-pressure West Sea island day trip — without the time commitment of southwestern islands like Heuksando — Jangbongdo is one of the cleaner picks, with a slow-travel feel and clear ferry access. Best treated as a half-day to full-day single-island trip.
