There is no best time to visit the Chhatrapati Shivaji Maharaj Vastu Sangrahalaya. You can come to visit this heritage complex at any time of the year. However, you should keep in mind that the museum remains open on all days of the week except Monday. If you like to explore Mumbai at its best then it would obviously be in the course of Ganesh Chaturthi. You can not only visit Ganesh Pandals but also visit all other places of tourist interest in Mumbai. Plan out trips to this amazing city that’s on the move at all times.
