Its spring is located at an altitude of 500 metres in the Tudora Comune, Botoșani County, in the eastern part of Suceava Plateau. It flows through the Jijia Plain, from north-west toward south-east and through the cities of Hârlău (formerly named after the river: Târgul Bahluiului) and Iași. It flows into the Jijia near Holboca, east of Iași. The quality of its waters is rather low, due to spills of industrial plants, especially in Iași. The Pârcovaci and Tansa-Belcești are located on the Bahlui River.
