Heavenly Hot Springs in Northern California

We may be the among the most powerful and influential nations in the world, but when it comes to the art of relaxing, America lags far behind. Most of us have yet to discover what the Native Americans, Japanese, and many other cultures have known for centuries — that immersing ones body in a natural hot spring is incredibly rejuvenating to the body and spirit.

In the past, most hot spring resorts were havens for hippies and New Age types, but these days more and more mainstreamers are discovering the calming effects of a good mineral soak. In Northern California theres a hot spring resort for every type of person — luxury spas, New Age retreats, pro-nudity spas, Japanese bathhouses, and even inexpensive mom-and-pop enterprises. Hot Springs are one of the rare benefits of living in an earthquake zone.

Along Californias fault line, a mere 4 miles below the earths crust, lies an enormous magma core that superheats the mineral-rich ground water and brings it gushing to the surface. This isnt just tepid tap water, mind you, but mineral-enriched, spring-fed, naturally heated nectar that seeps into your pores, erases your worries, and turns your skin baby-soft. Give it a try — your body will love you for it.

If youve never been to 150-year-old Vichy Springs Resort in Ukiah, you simply have to visit this place. Its not only a piece of classic Americana — its a California Historic Landmark and was a favorite retreat for Mark Twain, Teddy Roosevelt, Ulysses S. Grant, and Jack London — its the only naturally warm and carbonated Vichy mineral baths in North America. Located about 100 miles north of San Francisco, the no-frills resort is quite affordable, with room rates starting at $215, which includes full use of the mineral baths (bathing suits required), hot soaking pool, Olympic size swimming pool, and unfettered access to 700 private acres for walking and hiking.

Harbin Hot Springs

Nestled in a secluded valley near Middletown — about 30 minutes north of Calistoga — is Harbin Hot Springs, one of the largest and most popular hot springs in California. The atmosphere at this nonprofit retreat is decidedly New Age; youll see a good number of aging-hippie types in the buff (clothing is optional and rarely worn), mingling with the occasional urban professional. The 1,160-acre resort has a sauna, four mineral pools, and large redwood sun decks for that full-bodied tan. Meditation sessions, moon ceremonies, massages, facials, aromatherapy and Watsu (a warm-water massage) are also available. Lodgings range from inexpensive campsites and mens and womens dormitory-style rooms to cozy cottages. Within the resort is a health food store, two small cafes, and the Stonefront Restaurant that serves breakfast and dinner daily.
