When visiting hot springs or geothermal pools in Iceland, it's important to follow some key rules. First off, make sure to shower before taking a dip - sans swimsuit if possible. And don't forget to wear your swimsuit once you're all clean! Oh, and remember to kick off your outdoor shoes before heading into the changing rooms. Each place might have its own specific rules, so keep an eye out for those too. And most importantly, respect nature by staying on designated paths, avoiding harmful products, and leaving no trace behind. Just some simple guidelines to ensure everyone has a great time soaking in Iceland's natural wonders!
