The Snow Machine Festival has taken place at both the Remarkables and Coronet Peak skifields.
Organisers said the four-day event attracted a crowd of about 8000 festival-goers per day.
There were more than 1000 people at the Polar Bare at the Remarkables on Thursday.
The Bare started in 2022 with the first festival and is the world’s biggest annual spring ski swimsuit challenge, organisers said.
Snow Machine patrons from all over the world strip down to their boardies, budgies and bikinis for a slow fun run down the mountain.
This year there was a Snow Machine night ski event at Coronet Peak.
The event runs for four days and three nights, although most people stay the whole week.
The last of the festival’s events is today.
