Himachal Pradesh

Hi Everyone

I'm a solo Male traveller coming from the U.K.

I will be Travelling to Himachal Pradesh from Delhi on 17th October 2018

I have posted on here before but have changed my itinerary slightly.

How long would It take me to travel the route below,

Delhi - Shimla - Reckong Peo - Sangla&Chitkul- Nako - Tabo - Kaza - Losar - Manali - Dharamsala - Mcleodganj - Pathankot - Delhi

I would like to stop off in some places to enjoy the scenery and relax. Will the route from Gaza to manali be open at this time of year? What modes of transport can people suggest to complete the route? Will I need to book places to sleep before I travel?

Any help our suggestions will me much appreciated

Many Thanks
Emiel
