Geysir Hot Springs, located in the Haukadalur Valley of southwest Iceland, is a must-visit spot on the Golden Circle route. While Geysir itself is not very active these days, nearby Strokkur steals the show with its impressive eruptions every 5-10 minutes. Visitors can also explore bubbling mud pots and fumaroles in the area. Don't forget to check out the natural pool Kualaug for a relaxing soak. With no admission fee, Geysir is a great stop for those looking to experience Iceland's geothermal wonders up close.
