Embrach is situated in the "Embrachertal" (Embrach Valley), 6 kilometers northeast of the international airport of Zurich, in a wide U-shaped side valley of the river Töss. A plain of 500 ha size, 5 km length and up to 1.5 km width forms the ground of the valley. The plain is bounded by the slopes of the hill Blauen to the east, by the hill Dättenberg to the west, by the Ghei and the Egg to the south, and by the Tössschlucht (canyon of river Töss) to the north. The stream Wildbach drains the "Embrachertal" northwards into the river Töss at Rorbas. The landscape was formed by the Linth glacier during the ice-age.
