18 Natural California Hot Springs That Are Not Resorts

California’s landscape has more than 300 thermal springs, each offering a unique location coupled with geothermally heated water. These hot springs are tucked away in various corners of the state, from the rugged cliffs of the Sierra Nevada to the serene Imperial Valley at the border with Mexico.

Many visitors seek out hot springs for their potential healing properties. Since the water is often saturated with minerals such as calcium, magnesium, and silica, which are believed to have therapeutic effects on the body. But we all agree that sitting in a hot spring can be incredibly relaxing with the right setting.

Whatever is the reason for your visit, there is a variety of hot springs in California for everyone – from secluded pools surrounded by forests to expansive spa-like facilities with modern amenities. However, this post is all about hot springs in natural setting.

What is a hot spring?

California not only has the highest number of national parks, but out of 1,700 thermal springs in 23 out of 50 U.S. States, more than 300 of them are located in California. The list contains springs, pools, mud pots, mud volcanoes, geysers, fumaroles, and steam vents at temperatures of 200C (680F) or greater.

There are no universal definition for hot springs, just like there is not one for eco-lodges. But National Park Services define it as natural pools of water heated by the Earth’s interior heat. In volcanic areas, they can be extremely hot due, sometimes dangerously so. In non-volcanic areas, they are heated by the Earth’s normal temperature increase with depth.

The water in these springs often carries dissolved minerals, contributing to the mineral-rich content. In other cases, the springs are also carbonated.

Many hot springs are accessible to the public, often found in natural settings, national parks, or designated hot spring resorts. Others require a hike or drive through beautiful but rugged terrain, adding an adventure component to the experience. Each hot spring presents its unique blend of temperature, mineral composition, and setting, providing a different experience to visitors.
