Cologne Winter Carnival, Germany

Millions of people travel from all over the world to the city to attend Middle Ages-inspired celebrations. One of the warmest and booziest festivals to attend in the winter is this one. This is one of the most intoxicating winter festivals on this list because, being in Germany, the beer and glühwein are excellent and plentiful.

Crazy activities at the Cologne Winter Carnival include "Fat Thursday," when women cut off men's ties and give them a kiss, and "Rose Monday," a day of street parties, marching bands, and outrageous floats to cap off the weekend of drinking and fun. While businesses are still open, you can actually find people dressed up and in the holiday spirit, all week long, even while working, as the celebrations last for about a week.

Date: February 16 – 22
