안나 & I went out to the Han River and rented hybrid electric bikes and rode from 압구정 [Apgujung] to 여의도 [Yeouido] and back. I managed to snap this photo at 반포대교 [Banpo Bridge], but didn't really take photos of anything else.
Express Bus Terminal Station [고속터미널역] (Seoul Subway Lines 3, 7 & 9) - Exit 8-1
I know this sounds a little confusing, but follow these walking directions, and you will get there. Turn right out of exit 8-1. Walk for approx. 7 minutes until you run directly into a building. Walk around the left side of the building, and continue walking in the same direction you have been for about 50 meters. You will find a path beyond the parking, follow this to the right for another 50 meters or so. You will see a tunnel on your left; this leads directly to Banpo Bridge.
