Ålleberg, Nature reserve in Västra Götaland, Sweden.

Ålleberg is a table mountain southeast of Falköping in Västergötland, rising 335.2 metres above sea level. Its flat summit plateau covers only about 100 hectares, and the mountain is part of the Västgöta table mountains. The northern tip, called Ållebergs ände, is where the Ålleberg collar was found.

Ålleberg's northern tip, Ållebergs ände, is where two men found the three-ringed Ålleberg collar in 1827, one of Sweden's finest gold finds. In the Middle Ages the parishes around the mountain formed Ållebergs fjärding, a district of Vartofta härad. A 199.4-hectare nature reserve was established on parts of the plateau in 2002, also a Natura 2000 site.

Three marked trails lead across traditional grazing lands where animals maintain the open meadows from May to October. This living connection between pastoral practice and nature conservation shows how the two work together here.

Several parking areas serve different sections with spots near the rest area, the summit curve, and the Gliding Museum. The trails are clearly marked making it easy to find your way through the reserve.

The name Ålleberg likely comes from the local word ålla, meaning a hollow or depression, referring to a fissure on the mountain's north side. At the northern tip, called Ållebergs ände, two men found the three-ringed Ålleberg collar in 1827, one of Sweden's finest gold finds. Nearby, the never-drying Hokällan spring flows into a stone basin by the old country road.
