Here's a fun but obscure trail that goes around the west side of Biseul Mountain (Biseul-san or 비슬산) from Okpo on the north side. The trail begins in the edge of Okpo and connects into the more-traveled main entrance to Biseul Mountain park area. It's a very peaceful way to get from Daegu to the mountain.
