Tansa Wildlife Sanctuary in Thane district, Maharashtra, is only some 85km or so from Mumbai. It forms the catchment area around lake Tansa, which supplies much of Mumbai’s water. The sanctuary is almost three times the size of Sanjay Gandhi National Park in Borivali, Mumbai, but much lesser known, and seems to have much less wildlife. “There are atleast 54 species of animals and 200 species of birds do exist in the sanctuary. Major wild animals are Panther, Barking deer, Mouse deer, Hyena, Wild boar etc.”
I didn’t go inside the sanctuary, but in the peripheral villages, spent a morning photographing wildflowers, butterflies, and the odd reptile. This was early October 2013, right after the rains.
There is practically no place here to eat. So carry your snacks and water. If you like, try and carry your tea/coffee as well.
