The main group contains around 25 of them, and it extends from Assi Ghat (Next to us) in north to Raj Ghat. A highly recommended, although touristy, thing to do is take a dawn boat ride along the river starting from Assi Ghat to Manikarnika Ghat.

Dashashwamedh Ghat is known as the main ghat in Varanasi on the Ganges River. It is located close to Vishwanath Temple and is probably the most spectacular ghat.
