's latest rehab stint is bringing her closer to nature, with bicycling and whitewater-rafting excursions.
The 21-year-old actress entered the exclusive Cirque Lodge program in Utah following her July 24 DUI arrest
in Santa Monica after a car chase. Since then, she's been spotted in the Rocky Mountains on field trips from the facility. She and a group hit the road Aug. 16 for a 90-minute bike ride around Orem, Utah. The next day, Cirque took Lohan and others on an afternoon rafting trip on the Provo River.
Dressed in a pirate bandana, with some of her companions wearing black painted-on pirate moustaches, Lohan "looked like she was having a good time," says a source at High Country Rafting in Provo, Utah. "They were all splashing each other and stuff."
Lohan, who was said to have relapsed
just 11 days after leaving Promises rehab in Malibu, also has taken part in retail therapy while in Utah. At the Shops at Riverwoods in Provo, she was seen shopping at an Abercrombie and Fitch store and at the Rocky Mountain Chocolate Factory, where she picked up $70 worth of chocolates.
"She looked healthy," a Rocky Mountain employee says. "She seemed happy."
