Folsom Berlin is the European edition of infamous San Francisco Folsom street party. Thousands of leather and fetish guys come to Berlin this weekend for numerous parties and events.
The main event is the street fair itself. This is held outside on Saturday in the afternoon at the Welser- and Fuggerstraße. Most guys wear some fetish gear, some have really spectacular outfits. This is a decent street party though, so no outside action.
The main inside parties (with a lot of action) are Pig and Perverts. Beside that there are many other parties for specific fetishes, and most of the gay bars organise something as well.
