Admission to the grounds of the Auschwitz-Birkenau Memorial and Museum is actually free of charge; however, visitors are required to reserve an entry pass on the official website in advance to guarantee access. While the basic entry is free, the vast majority of visitors opt for a "Guided Tour" (officially called a Study Visit), which in 2026 costs approximately 85 to 110 Polish Zloty (PLN) per person depending on the language and length of the tour. These fees cover the cost of a professional educator and a headset system, which is highly recommended for understanding the profound historical context of the site. It is important to note that during peak hours (usually 10:00 AM to 3:00 PM), entry is only permitted as part of a guided group to manage the flow of people and maintain the solemnity of the memorial. If you wish to visit without a guide for free, you must typically book the "individual entry" slots that are available very early in the morning or late in the afternoon. All funds generated from paid tours are reinvested into the preservation of the barracks, ruins, and artifacts, ensuring the site remains a testament for future generations.
