Seooreung Gogae Green Link Trail is a natural green bridge connecting the slopes of Bongsan and Aengbongsan, and it is a walking path that is part of the Eunpyeong Dulle-gil. The route runs along the ridge from Bongsan through Aengbongsan to Gupabal, combining uphill and downhill sections. It is an Aengbongsan slope course where the Seoul Dulle-gil and Eunpyeong Dulle-gil meet. There are many stairs, so you become short of breath going up and down.
