Varanasi is the most beautiful and holy place to visit, its my hometown and I hope I might be able to help in exploring Varanasi in more traditional way.
1-First iconic to visit is Kashi Vishwanath Temple, this place attracts tourists from all over the world.
2- Ghats - My most favorite place of Varanasi, here in morning and in evening you can enjoy the scenic Ganga Aarti and you will find lots of crowd gathering there. try to view aarti from the boat, you will enjoy the mesmerizing view of the whole place. 3- Foods- Probably one of the best city to enjoy the streets foods and I recommend to must try Lassi near Kashi temple, its really delicious.
4- Sarnath - Around 10 Km from Varanasi, a UNESCO world heritage site, its good place for day outing, for photographer and traditional Varanasi Saree.
4 - Stay - There are many hostels near Ghats ,which are affordable and with good view. Some of the hotels are expensive too depending on your requirements.
I hope this would help you to know Varanasi more.
