Susan and her husband, who live in Switzerland, came on holiday to Greece and stayed in a hotel in Kalymnos.
On Sunday, she and her husband left their hotel to visit Telendo for mountain climbing.
The elderly woman, who suffers from dementia, sat in a restaurant to wait while her husband and a friend went hiking on the island. At some point, she left the restaurant and has been missing ever since.
She has short brown hair, blue eyes, height 1.55m. and she is stout. On the day she went missing, she was wearing a brown hat, gray Bermuda knee-length overalls, a light brown cardigan, a gray short-sleeved top, gray hiking boots and a gray sweatshirt.
She also wore her wedding ring on her hand.
