Jeju -Volcanic Island

Jeju island was produced by volcanic activities which occurred from about 1.2 million years ago. The island and its lava tubes are very well preserved. Three volcanic landscapes (Hallasan, Lava tubes, and Seongsan tuff cone) have been listed as protected sites for UNESCO's World Natural Heritage (2007). 

Lava Tubes -Manjanggul is the largest cave and the only one that is open to the public. The length of the cave is 7,416 meters.  The channel was formed through the path of the lava flows. There are more than 120 lava tubes scatted throughout Jeju island.

Volcanic Tuff Cone -Seongsan Ilchulbong is rising out of the ocean and is regarded as the finest example of Surtseyon-type volcanic eruptions.

Mt. Hallasan is 1,950 meters above sea level. It is a dormant volcano displaying pristine natural beauty throughout the changing seasons. There is no guided tour to the mountain top. Hiking to the peak takes all day (9 to 10 hours round trip).  

Eoseungsaeng --the guided tour took us to this small volcanic mountain in the Mt. Halla area. It may need additional two hours hiking from this location to get near the peak. 

This way does not lead to the Peak.

    The Peak is behind the cloud.
