Not much needs to be said about the Valley of Flowers trek. It is one of very rare treks that has a space dedicated to it on Wikipedia and rarer still, a place among the UNESCO World Heritage Sites. The name rightly suggests that it is a Valley full of Flowers and the spectrum of colours on display is unreal when you go there in months between July and September. The Valley has over 300 different species of flowers that have been identified and each of these are in full bloom during the season.
