The Dättenberg ridge lies between the lower Töss valley and the Glatt valley in the canton of Zürich. Its highest point is the Büliberg (Bülacherberg) at 597 m above sea level, southeast of the village of Eschenmosen. The 1,800-metre Dättenberg Tunnel of the Winterthur–Bülach–Koblenz railway runs beneath the ridge between Embrach-Rorbas and Bülach.

The western slopes of Dättenberg maintain traditional Swiss agricultural practices through small vineyards that contribute to local wine production.

The summit is accessible via several hiking trails that depart from different starting areas around the region. Routes are open year-round, though conditions vary depending on weather and the season.
