Tips for Visiting Hot Springs in Idaho

Safety should always come first when visiting hot springs in Idaho. Test water temperature before entering — some springs exceed 150 degrees Fahrenheit at the source and can cause severe burns. Never submerge your head in geothermal water, as harmful microorganisms can thrive in warm environments. Stay on established trails when hiking to remote springs, carry a first-aid kit, and let someone know your plans. If you are visiting a developed resort, staff will guide you, but at primitive springs you are responsible for your own well-being. Cell service is often unreliable near backcountry springs, so download maps and directions ahead of time.
