This is the Gotjawal Forest, characteristic of Jeju in general and south-west Jeju in particular – Global Education City is surrounded by it. The forest floor is covered with dark, broken, volcanic rock; the soil drains easily and the trees are typically shrubby and short.
I often run on paths through the forest, although I can only do so at weekends at this time of year. I regularly see deer and I’ve come across a herd of horses on several occasions. They’re wild as far as I know, but pretty docile.
