Hverir Geothermal Area, also known as Námafjall, is a must-see stop in North Iceland. With bubbling mud pools, hissing fumaroles, and colorful grounds, it's like stepping into a surreal volcanic wonderland. The rotten egg smell might hit you at first, but once you get past that, the views are out of this world. Don't miss the 2.5-kilometer Namafjall hike for even more breathtaking scenery and a break from the crowds. Just remember to stay on the designated trail and watch out for those active geothermal elements!
