Biryong Falls, Waterfall in Seoraksan National Park, South Korea

Biryong Falls is a waterfall in Seoraksan National Park, Sokcho, lying halfway between Yukdam Falls and Towangseong Waterfall. Its water drops over vertical rock walls of pinkish Cretaceous Seoraksan granite, whose joints guide the flow, and the loud sound of the falling water is compared to dragons rising toward the sky.

On 11 March 2013, the Biryong Falls valley area of Seoraksan was designated Scenic Site No. 95 by the Republic of Korea. The falls lie between Yukdam Falls and Towangseong Waterfall in Seoraksan National Park, Sokcho. The surrounding rock is Seoraksan granite from the Cretaceous period of the Mesozoic era, strongly pink in colour, with vertical cliffs developed along joints.

The name means Flying Dragon, taken from local legends that compare the sound of falling water to dragons ascending the mountainside.

Bathing or playing in the water is prohibited throughout the Seoraksan area to protect water quality, and littering is not allowed. No natural object, even a single stone, may be taken out of the national park. The falls lie halfway between Yukdam Falls and Towangseong Waterfall.

The rock is Cretaceous Seoraksan granite, strongly pinkish, with vertical cliffs following joints.
