Gunnuhver Hot Springs is Iceland's largest hot spring located in the southern tip of the Reykjanes Peninsula. It's a unique and fascinating place where you can experience the power of geothermal activity up close. The area is filled with boiling mud pools, steam vents, and even a massive 20-meter wide mud pool that bubbles vigorously. But here's the kicker: Gunnuhver got its name from a haunting story dating back 400 years. Legend has it that a woman named Gunna, suspected of being a witch, took revenge on those who wronged her. So, if you're up for an adventure and a bit of spooky history, Gunnuhver Hot Springs is definitely worth a visit. Just remember to stay safe and follow the rules!
