Residing close from mumbai, Matheran is a crowded hill station on any vacation time given. Be it summer, Monsoon or winter, tourist are attracted towards it anytime. Mini train travel time is too long. Takes almost 2 hrs to reach to the top. I suggest you to take taxi from Neral station which will cost you around 70-80 ₹ per seat. I also suggest you to visit here in Monsoon so you can enjoy the greenery as well as cold weather. In summer, there is no point in going as no greenery and because of dry, you will have dusty red feet as well:D And be aware of monkeys everywhere.
