The Sanjay Gandhi National Park in Borivali is the lung of Mumbai city, a patch of green in a sea of infrastructure. It is home to lions, tigers, leopards, deer, monkeys, snakes and many exotic birds. Both the Vihar and Powai lakes also lie within its borders.
You can visit the park and avail of a safari-type excursion through it in a minibus all through the week except on Mondays. Entry charges to the park are as reasonable as it gets -- Rs 30 per adult, Rs 15 per child.
When I visited the park on July 5 and took the minibus tour, I was lucky enough to spot five tigers (one was a white tiger), a lion and a lioness. And all of them looked much healthier than the ones at Mumbai's Ranibaug Zoo in Byculla!
