Brúarfoss is a beautiful waterfall in Iceland known for its stunning blue color, fed by glacier melt from Langjökull glacier. Visitors have the option to hike a 7 km trail to reach the waterfall, passing by smaller waterfalls along the way, or park at a new parking lot for a shorter 5-minute walk. While some may find the hike a bit long and unexciting, others appreciate the unique beauty of Brúarfoss and consider it worth a visit, especially if exploring the Golden Circle area.
