Occupied since Median times, Khoy (Salt) was named for the salt mines that made the town an important spur along the Silk Road. These days it's sugar beets that are making its fortune – you'll see trucks packed with them outside the sugar mill on the main road in from the motorway. While not a destination in itself, Khoy sits at the crossroads of several alluring secondary routes and travellers regularly end up here needing a bed for the night.
Roads radiate from Khoy like spokes, leading to Kapiköy in Turkey, to Jolfa and hence the Azerbaijani enclave of Nakhchivan, to Orumiyeh (via Salmas) and to Maku (and Turkey again). But the most interesting road heads northeast up winding curves and across a high alpine plateau ringed by mountains to the lonely town of Chaldoran (Siah Cheshmeh) and nearby Qareh Kalisa church.
