Jeju Island 맛집?? Walking trail?? Please recommend.

This summer vacation, I decided to go to Jeju Island for the first time in a while. Haha. Since prices have gone up these days, Jeju's prices have also increased, and there might be some rip-offs... but still, I decided to go for a trip after a long time. I haven't been there in so long that I don't remember where I went, what I ate, what I did, or where I gathered pine nuts.ㅠ

About five years ago, I went on a family trip with a tour bus package along with other senior groups, mainly focusing on sightseeing. Haha.
