Jeju Island: 1100 Altitude Wetland Trail in Mt Halla NP

Jeju is essentially one big volcanic mountain – Mount Hallasan – towering in the middle of the island. It’s almost perpetually in fog and clouds. The highest road on the island goes up to 1100 meters (over 3000 feet), where a boardwalk trail takes you around a volcanic wetland (which is actually quite a rare phenomenon as usually lava rocks are porous and water doesn’t stay). Local flora here is quite unique and several species are endemic.
