My most favourite place/hang out spot in Ahmedabad would definitely be the Sabarmati Riverfront.
Developed on the banks of river Sabarmati, this was the result of an sustainable development and environmental improvement.
A major tourist attraction now, owing to it's lush green promenades, beautiful parks and an all-round soothing ambience, once you visit here, you'll definitely love to visit it more often.
If you are the one who loves to read in solitude and enjoy some me-time, this is the right place.
Also the place enthralls with young crowd riding the rent bicycle, chit-chatting and having fun all the way.
Be it anyway, Riverfront is one place where you are sure to have some good time.
