It's a 3 day event in the gay village in Manchester(round Canal St) mostly (it's sectioned off and wristband entry only( but they do a parade through the city, a brilliant one at that.
It's somewhere people have a safe space environment with lots of gay friendly things going on. I say mainly in the village but lots of other local businesses have banners and welcome flags off and put events on.
It's a Manchester tradition now, very very popular and a great weekend. I've been to watch the parade loads of times and have been into Pride area a few years and had a great time.
We have plenty of other parades, Manchester Day, Chinese New Year, St Patricks Day, footballs ones, all sorts.
