The Maharashtra Nature Park is a one of its kind park in Mumbai, where one can observe both terrestrial and intertidal species of flora and fauna. This park is walking distance from the Sion railway station on the central line. Those that are familiar with the geography of Mumbai, will agree that it can't be more perfectly located.
Sprawling over 37 Acre area, several species of flora and fauna have been documented here which includes over 14000 varieties of flora, 85 species of butterflies, 125 species of birds, 3 species of mammals (which includes the Indian Flying fox and short-nosed fruit bat), over 30 species of spiders and several species of reptiles and amphibians (as of now not adequately documented).
I visited the park in April 2014 and got an opportunity to do macro photography. I am showcasing some of those here:
A tiny cricket on the tip of grass. Its unbelievable, the kind of sound these tiny things can make by rubbing their behinds!
