If you're coming from Mussoorie Mall on the Library side, it's a short 4 kilometre drive. Keep in mind that Mussoorie has two main gathering spots, one at Picture Palace and the other at Library Chowk.
To get to Seegreen from Library Chowk, you can get a private taxi for around Rs. 400/- but the fee is season dependent. Look out for the Seegreen Cafe 'The Best View Cafe in Mussoorie' signage. If you're ever in doubt, just ask any of the locals for direction to Seegreen, Hathipaon, or the George Everest point.
As you make your way, you'll notice the road winding through small settlements. From after you spot Convent of Jesus and Mary (Waverly School), it's a smooth journey through the lush forest. Roll down the windows, and enjoy the fresh, cool air and the soothing sounds of birds chirping.
After you pass through Bhatta village, keep an eye out for a left turn that will lead you to Hathipaon junction. This is a picturesque drive as you continue towards and pass the Nag Devta Mandir. Keep going till you get to Hathipaon junction, a quaint village that is home to five families. If you're ever in doubt, just ask any of the locals for direction to Seegreen at Hathipaon, Seegreen Cafe with view in Mussoorie, or the George Everest point.
