Birkenau is the second and largest part of the Auschwitz camp complex, built by the Nazi regime from 1941 on the flat land near Brzezinka, just outside Oświęcim in southern Poland. It is where most of the million or so people murdered at Auschwitz were killed, the great majority of them Jews. The camp was meant to be seen from the entrance, with the brick gatehouse and the railway line running straight through it, and that scale is the first thing that silences visitors. There is no softening it, and nobody who goes should expect to.
The ground here is flat, damp, birch-fringed farmland by the Soła river, and in the main season the car parks fill early and queues form at the entrance. Free entry passes are offered, but timed tickets or guided tours are common in busy months, and it is wise to check the current arrangements before you ride out. Motorcycle parking is normally available nearby, though gear is a problem: you will be walking for a long time in jackets and boots, in weather that is often cold and wet. Take layers. Take water. Plan for at least a couple of hours, and give yourself time afterwards to sit and gather yourself before getting back on the road.
Oświęcim itself is a normal small Polish city of forty thousand with petrol stations, cafés and a chemical works that has shaped its economy since the war. It is a place where people live, which is part of why the memory is difficult. Some riders plan this stop alone as a quiet day. Others find that it fits better at the start or end of a longer journey, where they are not trying to cross a mountain pass in the afternoon. The nearby Auschwitz I main camp, a few kilometres away, has its own museum, and many visitors see both.
The roads that lead here from Ostrava and the Beskids are unremarkable and fast, flat plain after rolling foothills. This is a place that asks for attention more than a good line through a bend, and the ride is best remembered as the part that gets you here.
