Anundshög, Sweden's largest burial mound, offers a fascinating journey into the Iron Age and Viking era, featuring impressive stone ship settings, runestones, and grave fields near Västerås. The outdoor site is generally accessible, though some paths may be uneven; it's best explored independently with informative signs in English, or through occasional guided tours for deeper insights. While open year-round, spring to early autumn provides the most comfortable conditions for a visit, as winter snow can obscure features. Entry to the historical grounds is typically free, with parking possibly incurring a minor fee, and a typical visit lasts 1-2 hours, allowing ample time to absorb the rich history and unique landscape.
