Healing Waters

Our geothermal waters emerge year-round at 90–102°F, naturally rich in hydrogen sulfide, bicarbonate, silica, sodium, lithium, manganese, chloride, and other trace minerals. This unique profile supports relief from inflammation, arthritis, joint and muscle pain, and skin conditions while promoting relaxation, better sleep, and lymphatic stimulation. The waters refresh completely in each pool every 30 minutes to 6 hours, remain untreated, and carry a naturally alkaline pH of 10.5–11.15 with a negative ORP of -230 to -313 mV — offering strong antioxidant effects that help neutralize free radicals and support cellular vitality.

Though the alchemy of Jacumba’s waters defies measurement, its chemistry is proven: alkaline pH, negative ORP, and a mineral profile recognized by the Balneology Association of North America as therapeutic. Safe, pristine, and free of harmful contaminants, our waters continue a tradition of healing recognized for centuries.

SODIUM -rich waters relax stiff muscles and joints, improving symptoms of rheumatological disorders and psoriasis. They enhance buoyancy, easing arthritic and muscular pain, while supporting natural electrolyte balance.
MANGANESE contributes to bone density, wound healing, and enzyme and antioxidant production. It supports immune function, lowers inflammation, regulates blood sugar, and is traditionally used to help with diabetes, psoriasis, osteoporosis, and epilepsy.
LITHIUM aids in neurogenesis and mental stabilization, helping calm the nervous system and offering protective effects against neurodegenerative conditions such as dementia.
CHLORIDE regulates electrolyte and pH balance, supports digestion by producing hydrochloric acid, and assists detoxification. It plays a role in electrical signaling essential for muscle and nerve function.
SILICA boosts bone density and collagen production for healthy skin, hair, and nails. It strengthens cardiovascular and immune function by lowering inflammation and cholesterol. With its natural exfoliating and antiseptic qualities, silica softens irritated skin and supports acne treatment.
HYDROGEN SULFIDE responsible for the signature sulfur scent — is one of the most beneficial aspects of our waters. Absorbed through skin and lungs, H₂S functions as an antioxidant and anti-inflammatory agent. It reduces pain and stress, improves circulation, supports skin healing, and offers respiratory benefits such as opening airways and easing congestion.

Our hotel guest rooms and hotel mineral hot spring pools offer respite and recharge for humans age 21+.

The mineral content of the waters here tends to tarnish silver jewelry. Not to worry – it can be easily polished back to its original luster or be left to do so on its own. If you want to be extra careful, we recommend leaving your jewels in your in-room safe before you soak.
