Gisseberget is one of the smallest table mountains in Västergötland in terms of surface area but it is also one of the highest, reaching 327 metres above sea level. The mountain lies in Tidaholm municipality and is thus not a part of Platåbergens Geopark. Gisseberget is a part of the same limestone plateau as Plantaberget, Varvsberget, and Gerumsberget, and the actual visible mountain thus consists only of clay shale and dolerite.
