The town of Calistoga, at the north end of Napa Valley, offers some of the world's best mud bath spa experiences. The reason for their renowned reputation is the special mixture of mineral-rich mud found only in Calistoga, the long history of mud bath traditions dating back to the 19th century, and the modern spa luxuries found in Napa Valley.

Calistoga's mud is not your average mud. Emanating from the long-ago volcanic activity of nearby Mount St. Helena, the legendary mud combines mineral-rich volcanic ash with waters from natural, mineral hot springs. The resulting mixture – this magical mud – has been touted for its many nurturing benefits.

Ingredients & Benefits

Calistoga mud is made with volcanic ash powder mixed with naturally heated mineral water. The mixture is prepared in a large concrete tub, producing a warm, heavy mud. The minerals present in the mud, including sulfur, are thought to offer various benefits for the skin, such as hydrating the skin, reducing inflammation, promoting general relaxation, and more.


Depending on the spa you visit, you can either "paint" the mud on yourself or "bathe" in a mud bath. The mud bath tubs are heated from the bottom and you lie on top of a layer of mud. Spa attendants lather mud on top until you are covered to the neck. You will feel suspended and weightless, for a truly relaxing experience. After a short period of time, the mud is washed off. Many of the same spas offer a soak in hot springs and mineral pools to complete your therapeutic spa experience.


In the early 19th century, when Spanish explorers arrived in what is now Calistoga, they found indigenous tribes already making use of hot mineral springs. The A'shoichamai or Wappo villages contained sweat lodges, and people in these tribes also partook in hot mud bathing to eliminate toxins. This practice wasn’t much different from the mud baths of today.


Are mud baths sanitary? Yes, every treatment incorporates copious amounts of scalding hot mineral water, which effectively acts as a sanitizer. Specifically, the sulfur in mineral water mixed with the alkaline in volcanic ash kills all bacteria every time.

What kind of mud baths are there?

In Calistoga, there are two ways you can expect to get muddy:

  1. Soak it in – bathe in a prepared tub already full of the good stuff and relax. After the restful soak, you’ll be helped out and given the opportunity to rinse and soak in a tub to remove any residual mud.

  2. Paint it on – a few spas offer the opportunity to paint your body with mud. You’ll spend time relaxing and warming up in the soothing sun before rinsing off.
