I need to travel to Vadodara and Kochi on an official tour later this month. As there is no flight connectivity between Vadodara and Kochi, I will have to go to Ahmedabad to board my flight to Kochi. I will have an entire day to spare in this historic city. So just thought do some local sightseeing within Ahmedabad city limits. It would be great if someone can guide me about the major tourist attractions at Ahmedabad that can be visited in one day. I may not be able to visit all Ahmedabad attractions in a single day, so please include the must visit places of tourist interest, especially the historical places and heritage sites of Ahmedabad.
