This being my first Solo trip ever made me a little nervous since Parvati Valley in Kullu is quite famous among Hippies for its magical 'Prasad'.
However, not being very familiar about the same and super excited about the beauty of Parvati Valley I decided to runaway!
My short itinerary for a 3D2N trip :
You can get overnight buses from Delhi to Kasol, which you can book from RedBus (even local HRTC buses can be booked) . But I chose to go via Bhuntar.
Delhi to Bhuntar AC Semi-Sleeper cost me around ₹900. From Bhuntar there are frequent buses to Kasol , I boarded the first one which leaves at 8am. They charge around ₹120 and take 2 hours to reach Kasol.
There are many options to stay in Kasol. I would suggest not to pre-book your stay unless you are going in peak season since booking online might cost you a bit more than the offline booking. For Groups - single room can cost from ₹200-500/night, whereas for Family - a decent room can cost from ₹1000-2000/night.
