Which way in
Plan on Kinnaur from Shimla. The Border Roads Organisation clears the Kunzum road through May: in 2026 it reopened for 4×4 vehicles on 20 May after more than six months shut, with heavy vehicles allowed only after full restoration. The date moves every year. See Is Spiti open?.
Weather
Kaza averages a high of about 5 °C and a low of about −6 °C in May, with little rain or snow. Days in the sun are pleasant; nights still freeze.
Who May suits
