Two sisters who died during a waterfall climb in Vietnam have been named as Beth Anderson, 24, and Isobel Mackensie Squire,19.
In a statement their family said "two bright lights have gone out". Another Brit Christian Sloan, 25, also died.
It has been reported the trio may have been with an unauthorised tour guide when the tragedy happened.
A guide in charge of a tour in which three British backpackers died has said they were swept away after ignoring safety warnings.
Half sisters Beth Anderson, 24, and Isobel Mackensie Squire,19, died along with fellow Briton Christian Sloan, 25, in an accident during a waterfall climb.
Their guide, Dang Van Sy, said the trio were killed after they ignored warnings to stay away from fast-flowing waters, in an interview with the English-language website Tuoitre News.
Mr Sy said that he had rushed to the edge of the water and instructed the women to stand up in the hope they could get out, but they were also swept away moments later.
An ex-Royal Navy sailor who died whilst climbing waterfalls in Vietnam was one of "life's one offs," his family have said.
The two women and a man were at the popular tourist spot with an unauthorised tour guide.
