Introduction to Gullfoss: Gullfoss is 2,500 meters wide and 70 meters high. It is one of the most spectacular waterfalls in Iceland and is located 125 kilometers northeast of Reykjavik. The water droplets splashed by the cascading waterfall fill the sky, forming rainbows under the sunlight, as if the entire waterfall is made of gold. The scene is so magnificent that tourists will never forget to leave.
