Mount Hallasan is a shield volcano which builds the centre of Jeju Island (Korea). It is 1950 meters high and holds up impressive basalt formations. The Mount Hallasan National Park is UN Natural National World Heritage and a very well managed site. Access is free. I approached it from the West and could not cross the summit into the crater as this region is protected, which I of course respect. Tried my new hiking boots here the first time: Vibram sole, tight grip and hard edges as always. Perfect. Asking for more.
