The British woman was on the island of Kalymnos together with her husband for vacations.
According to state broadcaster ERT, on the eve of May Day, the couple and a friend sailed to the nearby island of Telendos for hiking and climbing.
However, due to health problems, the woman sat in a restaurant in the harbour while her husband and his friend went climbing. When they returned, the woman was gone without leaving any trace behind.
Her husband alerted authorities, launched a search and rescue operation, and issued a Silver Alert.
