One can hire a full day Toto (Electric Rickshaw) ride to all of the tourist spots.
3 years back, I and my friend took the same and paid 200 rs (after bargaining ) and toured all the important nearby spots. I went there by Hazarduari Express and returned that day by Ganadevata Express, after the Toto dropped us at Jiaganj Ghat (on the other banks of AZ). Of course, it was extremely tight and we didn't waste any time in having a relaxed tour.
