The village is located along the western shore of Norway's fourth largest lake, Randsfjorden.

The village lies in the far northwestern part of Gran, just along the municipal border with Søndre Land.

[2] There is a 1.25-kilometre (0.78 mi) long car ferry from Bjoneroa to Horn on the opposite side of the lake Randsfjorden.

This is the only car ferry in Norway that operates year-round on an inland freshwater lake.

The local business community consists of the timber trade and millwork, in addition to seasonal tourism.
