Located in the heart of the city, The Sanjay Gandhi National Park is a treasure of wilderness that spreads for over 100 square km. Built in the 19th century, it is home to more than 200 species of flora and wildlife species, two lakes Vihar and Tulsi, Kanheri, a 2000-year-old complex comprising of more than 160 rock-cut temples, which is a well-protected archaeological site.
You can go there for half a day or make it a day trip, where you can easily spend a day in the lush wild national park. There are many activities to indulge in, especially that which kids would enjoy if traveling with a family like Tiger & Lion Safari, boating, a toy train ride through the forest, and hiking in the park. Note that all these activities are not available on Mondays.
There is a unique project called Living with Leopards initiated by the park to conserve the Leopard, where you get to experience their habitats through workshops and awareness programmes. They also host internships for students.
