Jämi is known for its esker landscape, like Soininharju Ridge and Niiniharju Ridge. Other specialities include expectional springs (Uhrilähde and Kuninkaanlähde) and depressions called “-vati”, like Koivistonvati. Ridges and depressions are at walking distance from the Jämi central area, which is next to Soininharju ridge. At the top of the Soininharju there is an observation tower.
