Petersberger Bittweg, Processional way and hiking trail in Königswinter, Germany

The Petersberger Bittweg is a historical pilgrimage route in Königswinter that winds about two kilometers through steep terrain, ascending from the old town center to the Petersberg mountain plateau. The climb gains roughly 250 meters and passes a series of religious stations spaced along the path at regular intervals.

The twelve surviving stations of processional altars and wayside crosses date from the 17th and 18th centuries; the route was one of five processional paths from Königswinter, Oberdollendorf, Niederdollendorf, Heisterbach and Ittenbach to the pilgrimage chapel on the Petersberg. The path was fully renovated in 1928, with partial rerouting. Stations 1–5 were restored before 1979 and in 1980/81, stations 6–12 in 1983 and 1984; the first five were renovated again from April to July 2019. Stations 6–12 were listed as monuments on 12 March 1990, stations 1–5 on 6 June 2018.

The route linked five villages — Königswinter, Oberdollendorf, Nieddollendorf, Heisterbach and Ittenbach — to the pilgrimage chapel on the Petersberg; the Bittweg is the last of these five processional paths still preserved. Its twelve surviving stations, processional altars and wayside crosses of the 17th and 18th centuries, are individually listed: stations 6–12 since 12 March 1990, stations 1–5 since 6 June 2018.

The trail starts above Königswinter's old town near the Mirbesbach stream at about 80 metres above sea level and climbs roughly 250 metres over two kilometres to the Petersberg plateau. It crosses the access road to the Grandhotel a few metres below the top. The upper stations 6–12 are on federal land; the lower stations 1–5 are municipal or private.

The route is the steepest ascent to the Petersberg: it starts above Königswinter's old town near the Mirbesbach at about 80 m above sea level and covers roughly two kilometres of path, one kilometre as the crow flies, to gain some 250 metres of height. Stations 6 to 12 have belonged to the federal government since it acquired the Petersberg in 1979, and two wayside shrines were stored in a depot during the 1983/84 restoration.
