The 3.7 km long Rönnby mountain biking trail (MTB Red) in Västerås. Many mountain bikers combine the Rönnby trails with those in the neighbouring Rocklunda area to get a little bit longer ride. The Rönnby MTB Red trail has parts with some technically challenging elements but it’s all bikeable with no drops. Quite simply, it’s a fun challenge. There are some smaller roots you can use to practice techniques and also potential mud holes when the weather is wet, but most trouble spots have alternative routes if you want to avoid the worst of it. The trails in Rönnby are actively maintained by the Västerås Cykelklubb (Västerås Cycling Club) and chances are high that you will meet club members on the trail.
Right next to the trail is the Rocklunda sports complex, which buzzes with activity due to its numerous indoor and outdoor sports facilities. The first stage of the [Bruksleden hiking trail] (http://bruksleden.se/) also starts here. So you get to experience the landscape transition from city to countryside and then the forest.
Anyone who’s a fan of craft beer will be delighted to learn that the local brewery [Coppersmith’s] (https://coppersmiths.se/rocklunda/) has recently taken over the restaurant at Rocklunda. Consider the potential of grabbing an after-biking beer at Coppersmith's Beergarden & BBQ.
If you want to extend your stay, there is the [Hem till Gården (Home to the Farm)] (https://www.hemtillgarden.se/), a hotel and a bistro within cycling distance where you can experience accommodations of a rural environment in the middle of the city.
