A Unesco World Heritage Site, Manjang Caves (admission: 2,000 won) is the largest volcanic lava tunnel in Jeju Island. Even if you’re not into geology, it’s worth visiting to see how lava once flowed here, leaving spectacular rock formations and patterns on the walls of the passage. At the end, you’re greeted by the world’s tallest lava column – 7.6m tall. Temperatures inside the tunnel can drop to a chilly 11 deg C so bring a jacket.
Formed when Mount Hallasan – a dormant volcano that’s also the tallest mountain in South Korea – erupted, the Jusangjeolli Cliff (admission: 2,000 won) is made up of majestic, cube-shaped lava rock formations. From observation decks overlooking the ocean, you’ll get a stunning view of the crashing waves at high tide.
