Getting to Yongseo from the new Hwangjeon IC couldn't be easier. Turn right at the first set of lights (onto Hwy 17) then stick to the right and take your first off-ramp. Turn left through the tunnel under the highway, then left again on the other side. Follow this service road up a small hill as it runs parallel to an off-ramp, then turn right at the next small intersection. Follow the road down under the railroad tracks and across the bridge into Yongseo Maeul.
