Woody Harrelson and Owen Wilson have been spotted frolicking in their skivvies in Peru, where the two stars went to visit the Casa de Milagros, a local orphanage they support, and do a little eco-touring.Wilson and Harrelson splashed around in an irrigation ditch in their boxers, and sought additional rejuvenation at the Hanaq Pacha Retreat Center, a yoga and spiritual retreat next to the Casa de Milagros orphanage which Harrelson also supports. The retreat has an organic vegetable garden and houses its guests in teepee-like structures called malocas, made from wood and canvas. The Chateau Marmont, it’s not, and that presumably suits these two Texan refugees from Tinsel Town just fine.
