Discover USA Best Hot Spring Spas for Ultimate Relaxation

Native, Nature’s Nurturing … Hot Springs

For thousands of years, mineral waters and hot springs have been treasured for their therapeutic and restorative powers. These natural oases, bubbling up from the earth’s own hydrothermal energy, were once humble bathhouses and towns centered around their healing waters.

Now the ancient practice of soaking in these geothermal springs has evolved into a multi-billion dollar industry, as modern wellness resorts integrate the traditional medicinal uses of hot springs with innovative spa treatments and luxurious amenities.

However, the core principle remains the same – immerse yourself in the warm, mineral-rich waters to soak away stress and emerge revitalized in body, mind, and spirit. From historic baths to five-star retreats, hot spring spas offer the ultimate environment for relaxation and rejuvenation.

From Sacred to Serene: The Evolution of Hot Springs Then Hot Spring Spas

  • Native Americans believed hot springs were a sacred gift from the Great Spirit with special healing powers. They considered them “Big Medicine Fountains” and neutral territory for warring tribes.
  • Hot springs are naturally heated underground when hot rocks and minerals trap hot water that rises bubbly to the surface. The water must be over 100°F to be considered a hot spring.
  • In the U.S., hot springs developed in three stages: used first by Native Americans, then by early European settlers emulating European spas, and finally as relaxation and fitness destinations.
  • Native Americans guarded the locations of hot springs and fought battles against settlers to preserve access.
  • Early Spanish explorers like Ponce de León sought mythical “Fountains of Youth,” likely inspired by legends of hot springs’ healing properties.
  • In modern times, hot springs are popular for relaxation and fitness. But the core appeal remains the natural heat and mineral content unlocked from the earth itself.
  • From historic baths to luxury five-star retreats, hot spring resorts and hot spring spas allow guests to soak in the therapeutic thermal waters.

Hot Spots: A Guide to Geothermal Springs in the U.S.

  • There are over 115 major geothermal spas in the USA and many smaller ones along with thousands of hot springs.
  • Saratoga Springs, NY had around 18 springs and hot wells discharging mineral water. Used by Mohawk and Iroquois tribes during hunting trips.
  • Warm Springs, GA also had mineral springs used by Native Americans. Became a resort area and was known for polio treatment from the 1920s to 1960s. Promoted by President FDR who had polio.
  • Hot Springs, AR was a popular commercial spa area modeled after European spas. 47 springs producing 4 million liters of water daily. Used by humans for over 10,000 years.
  • Calistoga, CA springs area settled by Pomo and Mayacmas Indians for 4000+ years. People came to use hot springs, fumaroles, and heated mud. Built sweat houses. Main attraction since the 1860s.
  • Harbin Hot Springs, CA – where Watsu water therapy originated. Remote springs over 2000 acres.
  • Hot springs come in various colors depending on sunlight, temperature, and microbes present. Microbes create color and thrive in different temperatures.


The Healing Embrace of Nature’s Hot Springs

  • Soaking in hot springs gradually warms the body, killing harmful germs and viruses.
  • Thermal bathing increases blood flow and oxygen, dissolving toxins and boosting circulation.
  • Hot spring bathing sends oxygen-rich blood through the body, nourishing organs and tissues.
  • Bathing increases metabolism, stimulating digestion and organ function.
  • Repeated hot spring bathing can normalize endocrine and nervous system functions.
  • Minerals like carbon dioxide and lithium are absorbed, stimulating immunity and relaxation.
  • Mineral springs contain negative ions that promote physical and mental well-being.
  • Sulfur-rich thermal waters can treat skin conditions like psoriasis, dermatitis, and infections.
  • Some mineral waters aid wound and injury healing.
  • Lower Blood Pressure: Soaking in hot water increases heart rate while lowering blood pressure, providing benefits similar to exercise with less strain on the heart.
  • Sleep Better: Soaking 1-2 hours before bed in ~103°F water for <15 minutes can help reduce insomnia by easing the transition into a deeper, more restful sleep.
  • Improve Joint Mobility: The warmth and buoyancy of water relieves muscle tension and reduces stress on joints, increasing range of motion. This allows safer exercise for arthritis sufferers.
  • Eliminate Toxins: Hot baths stimulate sweating to increase the elimination of toxins. Adding Epsom salts aids arthritis/rheumatism, and sea salt promotes healing and reduces inflammation.

Hot Springs … Who should not sweat it

Contraindications to Hot Water Natural Mineral Springs Therapy:

  • Conditions involving high fevers
  • Extreme Hypertension
  • Malignant tumors and cancerous conditions ( internal )
  • Liver, kidney, or circulation disorders
  • Conditions presenting the risk of hemorrhaging
  • Anemic Conditions
  • Pregnancy
  • Congestive heart failure, recent stroke, or recent heart attack
  • Bathing under the influence of drugs or alcohol

Having certain health conditions does not mean you cannot benefit from mineral waters, but you should take precautions. Soaking in very hot water can be risky if you have an underlying medical issue.

Check with your doctor first. If you have any concerns, contact your physician. A tepid or warm bath around 95-99°F is generally safe, similar to bathing at home.

Take care and consult a professional if you are unsure about using hot springs with a pre-existing condition. The benefits may outweigh the risks in some cases, but proceed cautiously.
