Gullfoss' water plunges 105 feet (32 meters) in two steps over a deep, dramatic crevasse in the river valley. As you approach, it's possible to hear the falls before you see the wild, tumbling water, and upon arrival, you can stand at an overlook at the top or walk down the path to the edge of the falls. The site is most often visited on full-day tours from Reykjavik, and is almost always included on various Golden Circle route tours. On any popular Golden Circle tour from the city, you're likely to also stop at highlights such as the Kerid volcanic crater, the famous Geysir geothermal area, the Strokkur geyser, and Thingvellir National Park. Some tours also include a stop at the Blue Lagoon, the Secret Lagoon, or other hot springs in southwest Iceland.
