Much of the remainder of the land is occupied by agricultural lands, specifically on the fertile plains over the river valleys. These geological structures resulted in a diversified landscape, dotted by parks, lookouts, belvederes, beaches and salient waters, including the Lagoa das Furnas (Lake Furnas) a volcanic crater lake and the manicured gardens of the Terra Nostra Garden (). The Furnas valley is a source of important horological resources, resulting from the active volcanism of the region, with fumaroles, boiling mud, thermal baths and at least one recognized tepid beach (Ribeira Quente). This valley includes 22 classified mineral-rich medicinal waters (the largest center of its kind).
