Ive also been to pin Parvati and adjoining areas...Solo. Dharamshal n Mcleod Ganj is a good option. Currently am thinking for spiti, but transportation as a solo traveller can be a little hectic.
Start your journey from mudh village in pin valley... mudh is famous for it's colourful mountains and hills... tara homestay is the best place to stay there... they also organise trek to pin parvati...
