Experience our Renowned
Cedar Enzyme Bath

Experience transformation in the only Cedar Enzyme Bath in North America and discover its powerful health benefits. Immersed in a warm bed of softly ground evergreens, your body is evenly supported with a gentle, penetrating heat. The warmth is generated biologically by fermentation. The bath boosts your metabolism and circulation, casts your skin in a radiant glow, and is profoundly relaxing.

Relax with a 75-Minute Massage or Organic Facial

The healing power of good hands remains the best way to relieve stress and revive body and soul. We specialize in exceptional 75-minute massage. Every day our guests tell us “that was the best massage of my life.” Look and feel fantastic with a rejuvenating organic facial. Our botanically derived, certified-organic skin care products will amaze you.

Feel Rejuvenated in Our Tranquil Meditation Garden

The culmination of the Osmosis experience is the Meditation Garden on our very private 5-acre sanctuary. This serene Zen garden will move you to deeper levels of inner peace and tranquility. It’s the perfect place to savor the increased levels of sensory awareness and well-being that follow spa treatments.
