Mountain Retreat
"We stayed in a Japanese style family room. It was clean and comfortable. Futons were a little thin so we stacked the extras for my husband. The food was delicious and the staff very warm and welcoming. We took the trailhead across from the hotel and enjoyed a run by the lake. Beautiful area."
