Day 5: Jeju, Udo

Seongsan Ilchulbong Peak, a UNESCO site. It's not the only dormant volcano in the world, but I think this is the most accessible one.

The top of the peak.

Taken from the peak.

The longest lava tube in the world, Manjanggul Cave.

At the end of our day, we just decided to drive around. This was taken at a higher level around Hallasan, and I think we were driving through the clouds, maybe.
