Today, tourism is rapidly becoming one of the main pillars of economic, social, cultural and political development.

The purpose of this research is to investigate and evaluate the tourist attractions of Darmin County (the land of historical castles) and find solutions to attract tourists and develop geotourism in the region. For this purpose, 8 geosites and tourist attractions (Abgarm Village due to its hot spring and the tomb of Sultan Ebrahim Reza, Lakhdarideh, Dushangan Tree, Mulla Emad Sand Hill, Hindalan Mosque, Tabas Asbad, Forg Castle and Torsh-Ab) were investigated.
