Holmsund lies at the mouth of the Ume River. To the west, across the river estuary, is a town called Obbola, the towns are connected by the E12 road which is carried over the river estuary by the Obbola Bridge. Both Holmsund and Obbola have wood and paper industries. From the southern end of Holmsund a ferry service runs to the Finnish port of Vaasa.
