Västanåfallet, Waterfall and nature reserve in Härnösand Municipality, Sweden

Västanåfallet is a cascade waterfall on the Eksjöån river in Härnösand Municipality, Västernorrland County. The water drops over rock ledges for a total fall height of over 90 metres. The falls and surrounding land form a 7-hectare nature reserve. South of the falls the river is called Hammarån before joining the Mjällån.

Västanå ironworks opened by the falls in 1744 and operated until 1867. Remnants remain on site, including a smithy building from the 1700s. The surrounding land became a 7-hectare nature reserve in 1978.

The falls gave their name to Västanå ironworks, which operated beside them from 1744 to 1867. A smithy building from the 1700s still stands, and the reserve's old lodge holds exhibits on the site's history and hosts local events.

The falls lie about three kilometres south of Viksjö, reached from county road (Länsväg) 331. The highest flows come in spring and early summer, so timing a visit to that period shows the cascade at its fullest. The surrounding nature reserve covers 7 hectares.

The river below the falls is called Hammarån before it joins the Mjällån; above the falls it is the Eksjöån. The falls drop over rock ledges in a cascade, and the highest flows come in spring and early summer.
