Get ready for a truly unique experience at Tvísöngur, a remarkable sound sculpture nestled on the hillside overlooking the fjord. It’s a bit of a walk to get to—about a 15 to 20-minute uphill hike along a gravel path—but you'll be rewarded with stunning views. The sculpture consists of five interconnected concrete domes, each resonating with a different tone from Iceland's tradition of five-tone harmony. Step inside, hum a few notes, and feel the incredible acoustics.
