Brúarfoss waterfall in Iceland is known for its stunning blue color, fed by glacier melt from Langjökull glacier. Visitors can choose between a short 5-minute walk from the new parking lot or a 7 km hike to see the waterfall. The hike offers views of smaller waterfalls along the way, making it a nice addition to a Golden Circle tour. While Brúarfoss may not be a must-see for everyone, it's worth a visit if you enjoy waterfalls and have the time to explore.
