The pass is traversed by National Road DN10, from Crasna, in Covasna County, to Gura Siriului, in Buzău County.

The road follows the course of the Buzău River; Lake Siriu is an artificial dam lake on the river, located at the southern end of the pass.

This is why the nearby region, known as Țara Bârsei was settled by Teutonic Knights in the 13th century, who built fortifications, to be prepared against such an invasion.

When Ottoman forces or other invaders would break through the pass, the village of Prejmer was the first place they encountered; the village was destroyed over 50 times between the 13th and 17th centuries, while the Prejmer fortified church was only rarely captured.
