It ends on the last Sunday in October at 03:00 local CEST time, when clocks fall back to CET.

CEST and CET are two phases of the same Central European Time zone. CET (Central European Time) is the winter offset at UTC+1, observed from late October through late March. CEST (Central European Summer Time) is the summer offset at UTC+2, active during the EU Daylight Saving Time period — meaning Berlin, Paris, and Rome run one hour ahead of their winter clock for roughly seven months each year.
