Tranquility Salt Cave
A serene wellness sanctuary lined with over 10,000 pounds of imported Himalayan rock salt boulders and loose salt granules covering a heated floor. The cave diffuses micro-sized pure salt particles (halotherapy) while offering heated vibro-acoustic biomats and infrared saunas.
The story
Behind an unsuspecting glass entrance at 30 Dillmont Drive, co-owners Leslie and Rob Dahn assembled a subterranean chamber out of five tons of imported geology. Over 10,000 pounds of Himalayan rock salt boulders—shipped in directly from Pakistan and India—form the perimeter walls, while a heated floor warms a bed of loose salt granules underfoot.
The real draw isn't just looking at glowing pink rock; it's breathing it in. A generator continuously grinds pharmaceutical-grade salt into micro-particles, filling the dimly lit room with an airborne mist while you recline in zero-gravity chairs beneath color-changing chakra lights. Book a session during a Full Moon Sound Bath, and resonant gongs vibrate through the salt-heavy air while microscopic sodium crystals settle around you.
Beyond the main cavern, the space houses a collection of targeted heat and frequency therapies. You can lie on a heated vibro-acoustic BioMat packed with amethyst crystals and far-infrared emitters, step into a full-spectrum infrared sauna, or soak in an ionic detox foot bath. Just heed the strict house rule before walking through the door: socks with colored soles or logos are strictly off-limits.
What it's like
Pulling up to Dillmont Drive feels like arriving at a routine office park, but the ritual inside is precise. You'll complete a QR-code waiver at check-in, stash your phone in a locker (devices must remain off or on airplane mode), and step in wearing clean, plain white socks—if you arrive with colored soles or logos, you'll be buying a white pair at the front desk or slipping on protective paper booties. Inside the cave, you'll sink into a zero-gravity recliner as the heated floor radiates through the granular salt. Sessions run 45 minutes and start strictly on the hour; arrive 15 minutes early, as latecomers are locked out to preserve the quiet environment.
The move: Wear your cleanest white socks and book a 'Full Moon Sound Bath' or guided meditation session inside the cave, reclining in zero-gravity chairs under the glow of color-changing chakra lights.

Good to know
What should I wear to a salt cave session?
Wear comfortable, loose clothing and clean, solid white socks with no colored soles, logos, or patterns. If needed, plain white socks can be purchased at check-in, or paper booties will be provided.
Can I bring my phone or take photos inside the cave?
No. All cell phones must be turned off or switched to airplane mode and stored in lockers outside the room to prevent salt dust from damaging electronics and to maintain a quiet atmosphere.
How long do salt cave sessions last?
Standard halotherapy sessions last 45 minutes and begin on the hour. Guests are asked to arrive 15 minutes early to check in, as late entry is not permitted once a session starts.
What other treatments are available on-site?
In addition to the main salt cave, services include full-spectrum infrared saunas, heated vibro-acoustic BioMats combining infrared heat and amethyst crystals, ionic detox foot baths, hydromassage beds, and crystal light therapy.
