Even New Yorkers need a break from the busy city streets and Aura Wellness Spa is the perfect retreat for some R&R. The four Therapeutic Grottoes are a highlight here; each are made of loess soil which contains micro-organisms and minerals that help remove toxins from the body. The four types include the Hwangto Dry Grotto, Crystal & Jade Dry Grottoes, Crystal & Jade Steam Grottoes and Stone Ice Grotto, and guests can choose to do one or a combination. Massages, facials, body scrubs and even teeth whitening are also offered. The spa also keeps late hours and is open seven days a week until 2 a.m. for all you night owls.
