Have you been to Cooper Spur Mountain Resort lately? WOW ... what a nice little Pacific Northwest Resort!! There is a new management team with a very friendly staff. The Cabins, Condos and Lodge Rooms are clean and welcoming! The Restaurant is quaint with a roaring fire and good food!! The outdoor hot tubs are a plus for star-gazing :) The Ski and Tubing Area has had great snow this year and the Ski Lodge is a wonderful gathering place for friends and family. Lodging is available year-round for hikers and bikers as well. If you are looking for a wonderful pacific northwest experience or just looking to get out of Portland ... give them a try. 541-352-6692
