First Lady Michelle Obama and her two daughters skied at a posh resort in Aspen, Colo., with the help of numerous instructors on private ski runs during Presidents Day weekend.

While President Obama was golfing with Tiger Woods in Florida, Michelle — who brought along a few friends and daughters Sasha and Malia — headed to the slopes.

They were given all-day private lessons with pro skiers from the Ski and Snowboard School of Aspen — a few instructors with the adults, and more with the kids, we’re told.

Other Aspen sources told us the Obamas, surrounded by security, skied at Buttermilk Mountain, one of the peaks in the Aspen Snowmass resort, which includes the fearsome superpipe featured on the Winter X Games. But Michelle and her daughters stuck to the beginner “Panda Pipe” area.

One witness told us, “Michelle was with two big groups and were in Aspen all weekend. Both girls were skiing, one in blue and one in a purple coat, and black pants. Michelle was in a navy ski suit. There were crowds of security guards dressed in black around them, all parked off the bunny slopes. Michelle and the girls were mainly going out each morning before the lifts opened.”

We’re told some wealthy Aspen visitors were annoyed when “air space was blocked because of [the Obamas’] plane, so others couldn’t get their private jets in. Many people nearly didn’t land or had to be diverted.” We’re told the Obama family stayed at the home of Aspen Ski Company owners Jim and Paula Crown, who are big Democratic donors. Their security team occupied another entire house next door.

Also in Aspen over the weekend were Leonard Lauder and new girlfriend Linda Johnson, who hosted a dinner Saturday night at his home with guests including Estée Lauder CEO Fabrizio Freda, Starwood Capital Group’s Barry Sternlicht, George Lindemann, Sloan Lindemann Barnett, Aerin Lauder, Julie and Billy Macklowe, William Lauder and Lori Kanter Tritsc
