The Copper Cave Salt Cave

The Copper Cave Salt Cave in Plaistow, New Hampshire is a dedicated halotherapy wellness destination — a genuine salt cave environment using pharmaceutical-grade Himalayan salt to create a therapeutic microclimate associated with respiratory relief, skin wellness, and deep nervous system restoration. Plaistow’s position at the New Hampshire-Massachusetts border makes the Copper Cave accessible for wellness seekers from both states — particularly the greater Salem-Haverhill-Londonderry corridor where quality halotherapy options are limited.

Salt cave sessions are passive and deeply restful: guests relax in comfortable zero-gravity chairs while micro-dispersed salt particles fill the air, creating an environment that supports relief for asthma, seasonal allergies, chronic sinusitis, eczema, and psoriasis while producing a profound quality of calm that many clients describe as unlike any other wellness experience. Regular session packages and memberships are available.
