The temporary closure of Jeju’s tourist attractions will be extended until October 5.
Please refer to the images below.
The above images were produced by Jeju Tourism Organization.
But it was hard to find on the official website and I referred to it on my blog.
The official website of Jeju Tourism Organization in English is the last notice in February.
