Tourism advice

I'm from Himachal and Jammu Kashmir, with family thinking of visiting UP for the first time in 29 or 30th of January this year and will stay until 4th Feb. not sure which places to visit but one is confirmed that is Ganga. Now I didn't wanted to visit UP in particular since I thought it was overrated especially ganga it's polluted as hell. But off let's not blam everyone There's always illiterate people in every community. Now when I think of it visiting UP isn't really that bad considering I was kind of believing in stereotypes. So, as a female traveler with a family of 7 deciding to visit, are there any tourism tips, safety and any suggestions for places to visit? Extra info would be nice too. Or anything I should avoid
