Are hot springs free?
Many natural springs on public land are free. Resorts and town pools charge entry. 5 of the 15 springs on Hot Springs Route are free to visit, and each page lists current prices with the source.
What is the difference between a natural hot spring and a resort?
A natural spring is a pool where hot water comes out of the ground, often with no facilities. A resort pipes spring water into built pools and adds changing rooms, food and staff. Check the type badge on each page.
What should I wear to a hot spring?
It depends on the place. Some require swimsuits, some are clothing optional, and some change rules after dark. Every page shows the dress rule its operator or land manager publishes.
How hot is the water?
Soaking pools usually sit between about 98°F and 106°F, and source water can be much hotter. Each page lists the temperatures its sources report.
