Orvis is a great place! 4 outdoor pools, ranging from the lobster pot (~5 person tub) to the pond (>2,000 sq ft). Great quiet ambiance, especially when it is snowing.
Head to Orvis after a day on the slopes in Telluride. There are 4 hot springs available to soak in, an outdoor sauna, and massage therapists. If you go at night, you can watch the shooting stars!
