Czantoria Wielka, Mountain summit at Czech-Polish border in Silesian Beskids, Czech Republic.

Czantoria Wielka is a mountain peak on the Czech-Polish border that rises to 995 meters and forms a natural divide between the Oder and Vistula river basins. A mountain lodge built in 1904 sits at the summit, and a 29-meter observation tower constructed in 2002 serves as a focal point for visitors.

The mountain belonged to the Duchy of Teschen until 1653, when territorial changes made it part of the Bohemian Crown. This shift in political control reshaped the region's administrative ties.

The name Czantoria was first recorded in a 1615 deed of Duke Adam Wenceslaus of Cieszyn; the older form Czartoryja referred to ground said to be ploughed by devils. Czech sources also link it to čantoryjka, the local name for common centaury, a herb once gathered here for folk medicine.

The site is accessible by chairlift from Ustroń, making the ascent easier for most visitors. Good walking shoes are important for the final approach and exploring the summit area.

The 29-metre steel tower on the Czech side, built in 2002, holds up to 170 people and on clear days shows the Malá Fatra, the Tatras, the Ostrava basin and the Katowice conurbation. A chairlift from Ustroń Polana, built in 1967 and modernised in 2007, ends below the summit at the Stokłosica clearing.
