If you are planning to visit Kullu-Manali in the month of October, do check the news below which states that Kullu Dusshera festival will start October 17, 2010 and end on October 23, 2010 this season. During this time of the festival the streets would be flooded with people and you wont be able to enjoy the beauty of Kullu Manali region at any cost. Huge herds of people will stock into the markets of Kullu and mall road of Manali. So, if you are considering to go Manali and enjoy nature, beware of this fact.
My suggestion is to avoid these dates and +/- 5 days as well to better enjoy what valley offers best, NATURE else the experience won’t be less than Indian Trade Fair 😉
