Askersund is a small wooden town at the northern tip of Lake Vättern in the province of Närke. It grew up around iron mining — nails and scythes were the local speciality — and the old centre still has the charm of painted timber houses and a handful of cafes along the harbour.
The main attraction is the lake. Vättern narrows here into an archipelago of about 50 islands, excellent for canoeing and small-boat exploring. Southwest of town lies Tiveden National Park, one of Sweden's wilder forests — deep ravines, mossy boulder fields, and lakes hidden in old-growth woodland. Several smaller nature reserves are scattered around the area as well. On the eastern shore, the old zinc-mining village of Åmmeberg is worth a detour for its industrial heritage and quiet swimming spots.
