Jeju Island

Depends on what you want to do, but spring time is my favorite! Lots of flowers in bloom (canola, camellia, etc) and so many good photo spots. Maybe a bit too cold for going in the ocean.

October was also nice with the cosmos flowers blooming.

Summer is hot and peak season so everything is more expensive and super crowded.

We went in august and it rained the entire time! It still was beautiful and fun, but wasn't a beach vacation. We stuck more to hiking and trying the amazing food!

Hot as blazes in July. I went in May and it was chilly. Maybe early June?
