The southern section of the Seefelder Straße (B 177), runs up the southern slopes and across the eastern side of the Zirler Berg. This road section is also called the Zirlerbergstraße. The Seefelder Straße is oriented mainly in a south to north direction and climbs up the mountain from the Inn valley from Zirl (622 m) with a gradient of up to 16% heading for Leithen (1,010 m) and then continues through Reith, Auland and over the Seefeld Saddle (1,185 m) about 4 km (as the crow flies) northwest of the Zirler Berg to Seefeld. Between Zirl and Leithen the road climbs 388 metres in less than 4 km, and continues to climb, albeit less steeply, as it makes its way towards the Seefeld Saddle.
