The cave in Gümüşhane most visited by tourists is the long Karaca Cave, popular because of its speleothems (= dripstone formations), including stalagmites, stalactites, columns and travertine pools. It is a fossil cave located between Torul and Gümüşhane, in which the lime-rich water percolating through fissures in the roof has slowly built up calcite structures of remarkable complexity. Other geological features of Gümüşhane include the numerous plateaux commanding views of the forested areas which surround them. These include the Zigana, Taşköprü, Artabel, Şiran and Kalis plateaux, which form fitting sites for the Summer festivals which are held there annually. Many native tourists participate in these festivals - not only for entertainment's sake, but also to shop for regional delicacies.

In addition to köme and pestil, rosehips, apples, and walnuts are notable local foods put to use in the many different desserts which are numbered among the regional specialities of Gümüşhane. Nor is the town's rich food culture restricted to sweetmeats : "mantı", "lemis", "erişte", "borani", "kuymak", "evelek, dolması" and "siron" feature among the savoury dishes local to Gümüşhane.
