Chotdaebawi is a stack of weathered sandstone left standing when the softer rock around it eroded away, and it happens to be shaped like a candle. That, plus the fact that it faces east into the sunrise, is the whole story — and it is enough to have made this little beach in Donghae one of the most photographed places in Korea.
The beach itself is short and pebbly at the southern end, sandy at the northern. It is fine for a swim in August, but nobody comes here for the swimming.
The walk is the thing: a boardwalk and suspension bridge threading along the rocks past the stacks, taking maybe forty minutes to do properly. Go at first light and you will share it with a hundred photographers, which is part of the experience.
