2,500 pounds of sea salt on the floor. CANēY Salt + Wellness Studio in Holliston offers a one-of-a-kind indoor beach experience for families. Kids dig and play in a floor covered in sea salt — a sensory experience that feels like the beach year-round. The active salt rooms disperse fine microscopic salt particles designed to be gently inhaled, supporting respiratory health, seasonal allergies, asthma, skin concerns, and overall immune balance. Features a dedicated Children's Salt Chamber, Adult + Teens Community Salt Chamber, and family sessions. Tip: Bring spill-proof water bottles and avoid wearing black (salt dust shows on dark clothing).
