While saying that Nordgren, 30, has put thousands of miles between herself and her scandal-ridden husband, 34, the U.K. tabloid the Sun reports that Nordegren has been staying in an $8,000-a-night, seven-room chalet outside the resort town of Chamonix since last Sunday.
Sources tell PEOPLE that Nordegren and her twin sister Josefin, along with several close friends, have been skiing in Les Houches, an exclusive ski area adjacent to the Chamonix valley under the watchful paid eye of a private five-man French security force.
Though the chalet includes a full staff as well as its own chef, Nordegren and her sister have been out to a local restaurant, hosting a New Year's Eve celebration which at midnight became the twins' 30th birthday party, according to one restaurant staffer.
In its report, the Sun quotes a "family friend" as saying that Nordegren wished to escape "from the minefield Tiger has created by his behavior" and that Elin told her husband "she needed a lengthy time apart to reflect on how they might possibly salvage the marriage."
