Hi Anika ! It has been 20 years since my trip ... And it stays in your soul... You can never forget it! Imagine flowers bursting with all kinds of colours everywhere, no buildings, no people - just you and your co-travellers! Do try and go back when you can... I heard you need to get some physical tests before the trek so dont leave it for too late. In those parts of the Himalaya, Ma Ganga is just born nearby at Gangotri, so she is young, like a 16 year old - very fresh and very chanchal restless with gurgling noises and tastes sweet and pure.
