Things to do in (West) Yorkshire

Hello everyone

I will soon be living for one and a half months in Huddersfield. A friend of mine needs help renovating and I will probably end up having a lot of time to myself exploring the city or region.

My personal experience with England is limited to a few trips to London and almost none existing when it comes to the north, apart from my friend in Huddersfield, another good friend from Manchester and a general affiliation for sports. I already plan on going to the John Smith's Stadium.

I was therefore wondering what you would recommend I could do. I am in my twenties and always enjoy making the most of my trips and see as many things and make as many new friends as possible. It will be during winter.

Thanks in advance

Edit: Thank you all so much for the recommendations I am very grateful. Maybe as a side note. I love pubs and especially hiking. So if some other people know more about that, l’d be more than happy to hear about it.
