A wooden haven nestled against the backdrop of Mount Timpanogos, The Spa at Sundance is so devoted to a seamless relationship between its services and the natural world, it can be hard to tell where its walls end and the plants outside begin. Vanity Fair sums up the universal appeal of the resort's hideaway: "There’s a mystical, magical quality that comes with being pampered high in the mountains in the middle of the dark woods." This backdrop helps promote the spa's mission to respect the healing powers of nature and to encourage personal transformation and wellbeing.

Many of the treatments here rely on raw ingredients. Scrubs are made from pure organic sugar and ground herbs, and an herbal poultice massage eases tense spots with muslin bags full of lavender, chamomile, and peppermint. Perhaps the most signature experience is the Sage and Sweet Grass Ritual, during which Great Salt Lake mud is applied to clients' skin. As they relax, the smoke from burning sage and sweet grass sweeps over their body in a ritual process called smudging.
