Deyr-e Gachin Caravanserai, located near Qom (though often associated with Tehran), is a well-preserved historical roadside inn dating back to the Seljuk era, with later additions. As one of the largest caravanserais in Iran, it features a vast courtyard, towers, and various chambers, offering a glimpse into the ancient Silk Road's infrastructure. Accessibility information is limited, but the site is generally flat. Visiting solo allows for independent exploration, while a guided tour can provide rich historical context. Seasonal restrictions are minimal, but the best time to visit is during the spring or fall to avoid extreme temperatures. The approximate cost of entry is minimal, with transportation being the primary expense. A typical visit duration ranges from 2 to 4 hours. It is advisable to arrange transportation in advance, as public transport options are limited.
