Cheongsapo Daritdol Skywalk

This guide to the Cheongsapo Daritdol Skywalk in Busan opens with a mystery: city hall has filed two wildly different price tags for rebuilding the same cliffside walkway, more than four times apart. It traces the site back to the Donghae Nambu Line, a coastal railway that ran along this cliff from 1934 until 2013, and follows how engineers turned the old track bed into a cantilevered deck hanging above the waves. Stand where the walkway curves back toward the cliff, on the old rail bed itself, to catch both angles of the loop.
