Anyone entering the Badelunda nature reserve experiences one of Sweden's most archaeologically dense areas. Burial mounds, stone circles, individual menhirs and Hålvägar (hollow ways), which have been carved into the ridge of Badelundaåsen by millennia of trampling by humans and animals. The Ice Age ridge rises in places 20 meters above the surrounding land. Below the medieval church bubbles the Jungfrukällan, a spring said to have healing powers.

Anundshög is no ordinary burial mound. With a height of nine meters and a diameter of 60 meters, it is the largest in Sweden. It is surrounded by one of the country's largest Skeppssättningar (stone ships), several stone circles, and individual menhirs from the Viking Age. The entire area is located in the Badelunda nature reserve, which holds over 200 archaeological monuments. The so-called Hålvägar (hollow ways), created by millennia of trampling by humans and animals, are still recognizable today.

Björnön (just outside town of Västerås) is normally off limits for mountain biking, but a short 3 km track has been approved by the county administrative board and is maintained by a small business nearby specialising in renting out outdoor equipment. Trail is well marked. Both bus stop and car park nearby. In summer time there are a lot of bathing opportunities along the shore of Björnön.

Fun and technically challenging short trail section between Framnäs and Börjnön. Difficulty level S2. A lot of rocks and roots. Take care if wet as it become slippery. Elbow and knee protection recommended if you are beginner MTB or use click shoes. Offers partial view of lake Mälaren and Björnön. Beware that area is also frequently used by a nearby horse riding club so slow down or stop if you meet riders. Call out to avoid frightening the horses unnecessarily.
