Hallyeohaesang National Park, Marine national park in southeastern South Korea.
Hallyeohaesang National Park is a marine national park in southeastern South Korea covering approximately 545 square kilometers. The terrain comprises coastal sections with numerous islands and peninsulas interspersed with mountainous regions crossed by hiking trails.
The park was founded in 1968 as South Korea's first marine national park, created to protect the southeastern coastline. This establishment marked an early turning point in South Korea's efforts to conserve marine ecosystems and coastal landscapes.
Local temples scattered throughout the park remain active centers for worship and celebration, reflecting the deep connection between coastal communities and the sea. Visitors encounter traditional ways of life still practiced by residents, from fishing methods to seasonal rituals.
Different sections of the park can be reached year-round through a ferry network connecting the mainland to multiple islands. Visitors should prepare for changing weather conditions and check ferry schedules in advance, as they can vary by season.
In 2015, North Pacific right whales were spotted in the park's waters, marking the first sighting of this species in South Korean waters in 41 years. This rare observation revealed that the ocean in this area plays a crucial role in supporting endangered marine life.
