Hwangnyeongsan Observatory on the Seomyeon side of Busan is a hiking course that looks down over the city center below. From it you can see the Nakdong River, Busan Port, Yeongdodaegyo Bridge, and the direction of Dongnae and Geumjeong-gu, along with the night view. Around sunset you can watch the sun set over the city center. Many tourists come here, so the observatory is crowded rather than quiet.
