Top 3 beaches on South Korea's west coast

In my opinion I think these are the top 3 beaches on the west coast of South Korea.

1) Mallipo Beach (만리포해수욕장)
Located in Taean-gun, Chungcheongnam-do province.

2) Seonyudo (선유도)
A little island off Gunsan.

3) Daecheon Beach (대천해수욕장)
Located in Boryeong-si, Chungcheongnam-do province.

(Not the clearest photo. This was taken when the beach was overrun by people due to the annual Mud Festival held here every summer)
