Geobukseom is a tourist site on the sea in Songdo, Busan, connected to a small rocky island by a bridge. A 365m cloud walkway includes a section of clear tempered glass, and the night sea and night views stand out. Free telescopes are available, and the site is reachable on foot from the Songdo cable car, taking 10 to 30 minutes to look around. Typhoons have blocked the entrance to the cloud walkway and closed some sections, so visitors need to watch their step.
