Heullimgol Valley설악산 흘림골

At a glance

Heullimgol is a deep valley on the Yangyang side of Seoraksan, named for the mist that so often hangs in it and makes the day look overcast. The trail passes 20 m Yeosim Falls, then climbs a very steep 300 m to Deungseondae, a lookout over the Manmulsang crags, before continuing past Deungseon Falls and Geumgangmun Gate down Jujeongol Valley to the Osaek mineral spring. Closed after a 2015 flood and rockfalls, it reopened in 2022 with detours and protective tunnels at 22 rockfall spots. Entry is capped at 5,000 people a day in timed slots, so you must reserve through the Korea National Park Service.

Tips

• 01
  The 300 m from Yeosim Falls to the Deungseondae entrance is very steep, so wear proper hiking shoes.
