The funeral of Isobel Squire and Beth Anderson will take place in Sheffield today, following their deaths last month.
It is open to family and friends of Izzy and Beth only.
The tragic pair were almost seven weeks into a tour of South East Asia when their bodies were found at the Datanla Waterfalls in the Da Lat area of Vietnam.
A spokeswoman for Beth and Isobel’s family said that their lives would never be the same again.
She said: “Two bright lights have gone out. They shone brightly for 24 and 19 years for everyone who loved and adored them and everyone who came into contact with them.
“Sisters, Beth and Izzy were living a life of adventure and did so, right to the end.”
Police in Vietnam have launched an investigation into the circumstances surrounding the deaths.
