Overview

National Highway 505, was designated Himachal state highway 30 prior to its being notified on 4 March 2014 as national highway. The highway runs through high altitude cold desert area of Lahaul and Spity valleys which receive negligible rainfall. The terrain is barren and treacherous, prone to landslides and disruptions. The road is narrow and rough at places and crosses high altitude Kunzum pass, requiring good driving skills in mountains.[6] NH-505 provides connectivity to some major Buddhist monasteries and various interesting places.[7]

Route

Kinnaur district

The route of NH-505 starts at Khab in Kinnaur district from National Highway 5. It connects Khab Sangam, Nako and Chango, then enters Lahaul and Spiti district at Sumdo.[2] This is the preferred point of entry to Spiti valley which is located at an average elevation of 3350 meters (10,988 feet).[5] This mostly all-weather access point to Spiti valley from Khab is at an elevation of about 2600 meters. Travelling from Shimla to Khab gives a chance for travellers to gradually acclimatize themselves to avoid altitude sickness.
