The group of French tourists were reported missing at 9pm on Sunday when they did not reach Kebnekaise mountain station after departing Nikkaluokta at lunchtime.
Police searched through the night on snowmobiles, but the weather was too poor to use a helicopter. On Friday morning a police helicopter and two Armed Forces helicopters were used to search for the group.
Shortly after 10am police said the six tourists had been found safe and well. Four of them were found in the mountains and two at Nikkaluokta.
“We still don't know how they spent the night or what happened,” police spokesperson Marie Jakobsson told TT.
