Jeju Olle Trail Route 10

Jeju Olle Trail Route 10 delivers the most dramatic coastal hiking in Korea over a 15-kilometer stretch between Hwasun and Moseulpo. The path weaves past black lava beaches, traditional haenyeo fishing villages, and the island's southernmost point, where volcanic basalt columns and sea stacks create a landscape that outperforms #5. Unlike any other coastal trail in East Asia, it combines raw volcanic geology with cultural immersion, and a 2025 survey found 87% of hikers rated the seaside views as "exceptional."
