Kullu Manali –
I stayed there for 2 and 1/2 days.
1st half day: Local sight seeings – 2 temples (Hadimba temple and Manu temple) & Market in Manali.
Second day: Rohtang pass and some “S” valley where you can do para gliding over the hills.
3rd Day: Kullu (We did Beas River rafting), played in the river and then headed to manikaran (Hot valley springs + Sikh temple)
That was our itinerary. But I believe you can spend upto 7-9 days there.
Contact Himachal Pradesh tourism for more details (we booked rooms thru them).
