Long one of Europe's great gay playgrounds, and - along with Prague - a top GLBT destination in Eastern Europe, the beautiful and culturally rich city of Budapest is hosts a 10-day-long Budapest Gay Pride in early July. The dates for 2013 hadn't yet been announced but will be posted here as information becomes available.
Here's more on Budapest Gay Pride from last year:
After some initial controversy, when the Budapest police canceled the Gay Pride March in 2011, the festival and parade went as planned, in early June. This year, the Pride festivities take place a bit later, in early July, kick off on Sunday and include a full slate of arts and cultural events, including film screenings, parties, workshops, art exhibits, political and LGBT rights discussions, women's pride and men's pride celebrations, and lots more.
The big event is on Saturday afternoon at 4 pm when the Budapest Gay Pride Parade marches through the city, from City Park to Kossuth Square, via Heroes' Square, Andrassy Avenue, Bajcsy-Zsilinky, and Alkotmany Street. The Pride March follows a Pride Picnic (from 1:30 to 4 pm) with music, theatrical performances, and speeches. Following the march will be a Budapest Gay Pride Rainbow Party, from 10 pm until 4:30 am, at Durer Kert (here's a map of the location).
Additionally, gay-popular bars, restaurants, hotels, and shops in the area have more going on than usual during Pride week. Check online resources about the Budapest gay scene, such as the GayGuide.net Budapest Gay Guide and the NightTours Gay Guide to Budapest. Also take a look at the excellent visitor site produced by the city's official tourism organization, the the Budapest Tourism Services Center.
