Mark and Elliott landed in Austria on Sunday morning (6 April) for the week-long festival, where days are spent skiing and nights are transformed into parties.
TOWIE's Elliott has been sharing plenty of photos on Twitter and it seems like the boys have hit the slopes in style.
Captioning one snap, Elliott told fans: "First beer of the day!!!"
Mark, who is engaged to Coronation Street actress Michelle Keegan, excitedly told his Twitter followers on Saturday (5 April): "Just packed my case!! Full to the brim of top end @Dare2bOnline ski gear!! #lookgood #skigood @Snowbombing here we come!!"
We're not surprised that Mark was so excited, as he last enjoyed a winter ski holiday in April last year, so no doubt he was desperate to get back on the snow!
It's been one holiday to another for Elliott, who headed back to Alicante in Spain, following TOWIE's series finale last week.
Elliott, who runs his own restaurant in Spain, also spent some quality time with his children by relaxing on the beach and going quad biking.
Elsewhere, Mark recently made a brief return to TOWIE in the last series, when he supported Elliott during his pro boxing debut.
Viewers saw Mark cheer on Elliott, who successfully beat rival Lewis Bloor at the fight in Romford, Essex. A proud Mark, who quit TOWIE in November 2011, was then seen lifting Elliott on his shoulders as he celebrated his cousin's success.
