The source of the Msta is in Lake Mstino in the Valdai Hills immediately north of the town of Vyshny Volochyok. The river flows north, accepts the Berezayka from the left, and enters Novgorod Oblast. There, it accepts the Uver from the right and turns northwest. Downstream from the town of Borovichi, it forms the border between Borovichsky and Okulovsky Districts, and further downstream between Okulovsky and Lyubytinsky districts. It departs from the border to the north, and downstream of the settlement of Lyubytino sharply turns southwest. It makes one more curve at the border with Krestetsky District and has its mouth downstream of the settlement of Proletariy.
