Located at The Osthoff Resort on Wisconsin's Elkhart Lake, whose waters were considered sacred by Native Americans, Aspira Spa combines indigenous healing techniques from around the world with local, organic products and a feng shui-influenced design for a holistic experience. A globally minded spa menu showcases an eclectic array of treatments, from a Moroccan hot oil massage to a traditional Hawaiian lomi lomi. However, guests wishing to sample a little local flavor can opt for a body masque using chamomile and lavender harvested from the resort's garden, or cedar aromatherapy inspired by Native American rituals. While leaving the spa may be difficult, be sure to set aside some time to explore the historic hotel grounds. Bike rentals are available by the hour or day, as well as sailboats, canoes, paddle boards and a variety of other lake-going vessels.
