The Solling is a range of hills up to 527.8 m above sea level (NN) high in the Weser Uplands in the German state of Lower Saxony, whose extreme southerly foothills extend into Hesse and North Rhine-Westphalia. Inside Lower Saxony it is the second largest range of hills and the third highest after the Harz (Wurmberg; 971 m) and the Kaufungen Forest (Haferberg; 581 m). Together with the smaller and lower Vogler range and the little Burgberg to the north, the Solling is part of the Solling-Vogler Nature Park.
