One of the hidden secrets of Napa Valley is its naturally occurring mineral hot springs in Calistoga.
Powered by geothermal and volcanic activity, these mineral hot springs were discovered over 8,000 years ago. The earth's heat from below the surface warms the water, creating hot springs that are rich in minerals. Today, these healing waters are piped directly into the pools and spas of Calistoga, offering therapeutic benefits to the skin, body, and mind.
These remarkable waters are infused with skin-loving ingredients like sulfur, calcium, and magnesium. The hot springs and mineral pools can also have healing effects, ranging from deep muscle relaxation to aiding skin conditions, promoting sleep, and providing stress relief.
The best way to access these hot springs is to book an overnight stay or a spa service at one of Calistoga’s many resorts and spas. Most offer at least one pool that pipes in these mineral-rich waters, but many offer several pools at various temperatures, from piping hot to the ever-popular cold plunge! Be sure to peruse these spa menus closely – most resorts and spas offer communal hot springs, while a few select locations offer private or in-room experiences for couples or small groups.
Add a Mud Bath
For the ultimate therapeutic spa day, start with a soak in Calistoga's famous mud baths. The same geothermal and volcanic activity that produce hot springs also led to the presence of warm volcanic ash – creating mineral-rich mud, renowned for its skin-nourishing magic. Follow up your mud bath with a plunge into a mineral pool to leave you feeling relaxed and rejuvenated. Calistoga's mud baths and mineral pools are not just an experience – they're a love letter to self-care.
Insider Tip: before you settle in for a soak, we recommend checking out the Old Faithful Geyser, located just north of downtown Calistoga. This geyser erupts every 30 minutes, shooting hot water up to 100 feet in the air.
