Red Rocks Banya, Denver

Within Red Rocks Banya's traditional Russian sauna, nothing has changed since medieval times. The steamy, wood-paneled banya is steeped in history as much as sweat—it harks back to a ritual that has opened pores and provided warmth in the icy Russian climes for centuries. The spa's rustic decor, punctuated with Russian nesting dolls and trinkets, heightens the sense of historicity. After an organic honey-mask treatment and a glass of organic herbal tea, clients can slip into the candlelit cold-plunge pool to cool down or easily remove the skin from tomatoes.
