Hey we are leaving for tosh and kasol next week! I guess Google could really help. Even I learned from one of the travel article but we googled and it pretty much helped. If you need some. Help. In planning do let me know
You can go on your own from delhi. I have done this exact trek before. You have to take a bus from delhi to Bhuntar. From there you can opt a bus or taxi service towards kasol. And from there one bus will take you to bershaini. From bershaini you have to trek for kheerganga. There is a village called Nakthan, you'll come across when you'll trek towards kheerganga. Once try their momos or noodles. Very delicious. Good luck. Happy Travelling!!
