Its very correct in saying it queens of hills. It is very easily approcable from Delhi-NCR, you start from Friday night reach there by Saturday morning then you will be having 2full days and you may return back in Sunday night and resume your work/office from Monday if you really have to and you specially if cannot afford to manage your boss. This is USP of going to Mussorrie during weekend.
I have been there couple of times the last was in recent past and that time it was the 1st snow of that season and moment I reached Barlow Ganj it started snow and finally when I reached the epic mall road the snow was upto 1feet and our vehicle cannot go further, so we spend some of our most mischievous time over there.
And finally when snowfall stopped we started again our journey uphill and happened to see Gunhill, campty fall, laal tabba, dalhousie.
I had no other option as I had to be back to work on Monday so I returned back but one thing for sure is if you have not been to Mussorrie till now, you are missing a big thing, so who ever is in that list just head out there and have a wonderful experience enjoy.
