Dear Nalin,
Greetings from Top China Travel! Thanks for your message.
If you take a Yangtze River Cruise, yes, you will have chance to visit the Three Gorges Dam. And I think that will be the most convenient and substantial way to do the visit.
More info, please click Yangtze River Cruise
If you have any further question, please feel free to contact us.
Kind regards,
Zoe
