There’s something unforgettable about soaking in a hot spring surrounded by nature.
Warm, mineral-rich water bubbling up from the earth.

Natural hot springs—often called “wild” springs—are undeveloped and free to access.

No fences, no admission fees. Just you and the earth.
But they come with responsibility. Always pack out your trash. Respect the land and fellow visitors.
Test the water before entering—it can be hotter than it looks. Some springs require long hikes or permits, so plan ahead.
