The basalt cliffs. The beaches. The fields. Everything came from volcanic eruptions over millions of years.<\/p><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">What you don&#8217;t see from the surface: an extensive underground network of lava tubes\u2014tunnels formed when molten rock drained from beneath the island.<\/p><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Manjanggul is one of these tubes. And you can walk through it.<\/p><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>What it is:<\/strong> A lava tube 7.4 kilometers long total (one of the world&#8217;s longest). Only 1 kilometer is open to the public, but that&#8217;s plenty.<\/p><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>How it formed:<\/strong> At least 100,000 years ago, during one of Hallasan&#8217;s eruptions, lava flowed downslope in a channel. The surface of the flow cooled and hardened into a crust. Beneath that crust, molten lava kept flowing. Eventually the eruption stopped and the liquid lava drained out. What remained: a hollow tunnel with solidified lava walls.<\/p><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Many lava tubes collapse over time or fill with debris. Manjanggul remained intact for 200,000+ years. The geological features inside\u2014lava stalactites, flow marks, secondary mineral formations\u2014are exceptionally well-preserved, making it a UNESCO World Heritage Site that Koreans seem pretty proud of.<\/p><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>What you&#8217;ll see inside:<\/strong><\/p><ul class=\"[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"><li class=\"whitespace-normal break-words pl-2\">Lava tube ceiling: 10-20 meters high in places, formed rock crust<\/li><li class=\"whitespace-normal break-words pl-2\">Lava pillars: Where dripping lava hardened mid-fall (like stone icicles)<\/li><li class=\"whitespace-normal break-words pl-2\">Flow marks: Patterns in the walls showing how lava moved<\/li><li class=\"whitespace-normal break-words pl-2\">Multi-tiered structure: Multiple lava flows created layered floors<\/li><li class=\"whitespace-normal break-words pl-2\">Stone Turtle: Massive lava column formation (highlight of the walk)<\/li><li class=\"whitespace-normal break-words pl-2\">Temperature: 11-21\u00b0C year-round (cool even in Jeju summer heat)<\/li><\/ul><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Remember how I said almost everything visible on Jeju came from Hallasan?
