Hallasan National Park

Getting around: From Jeju City, take a bus to one of the main trailheads (Seongpanak or Gwaneumsa, about 40-60 minutes); trailhead access requires advance timed-entry reservations for the summit routes.
Hours: Trail entry times are restricted and vary seasonally; typically the last entry to reach the summit is required by early-to-mid morning to ensure a safe return before trail closure in the afternoon.

Hallasan is South Korea's tallest mountain and the dormant volcano that formed Jeju Island itself, its crater lake summit (Baengnokdam) reachable via a genuinely demanding full-day hike on one of two summit-accessible trails. Lower elevations pass through subtropical forest, transitioning to alpine scrub and volcanic rock near the top, with dramatically different ecosystems compressed into one climb.

Reaching the summit is a serious undertaking — typically 8-9 hours round trip on the Seongpanak trail — so it demands real planning: an early start, advance reservation where required, proper gear, and a realistic assessment of fitness, while shorter trails to lower viewpoints suit visitors who don't want to commit to the full climb.
