A student fell to her death while posing for a photograph on cliffs at Seven Sisters, an inquest heard.
Hyewon Kim, 23, came to the UK to study English and on 22 June took a trip to Cuckmere Haven, East Sussex, alone.
She asked a stranger to take her picture, but as she jumped in the air for the shot she lost her footing and fell 200ft (60m).
The court heard Ms Kim, from South Korea, suffered catastrophic injuries in the fall.
Eastbourne senior coroner Alan Craze recorded a conclusion of misadventure.

"What we would say is to urge people to stay well away from cliff edges.
