When I was in trip to manali, I visited solang valley, place is not so good as it is hyped, just a wastage of money, nothing is there, yes paragliding is there but you can do paragliding in other places also more the persons are not trained enough there are chances of accidents. my suggestion is if you visit manali go other places near by dont waste money to go to solang valley if you want to go by bus beacuse taxi will charge high & its not worh for money
