Tunnels are basically actual magic tricks hidden inside ancient rock.
It is pretty mind-blowing when a traveler realizes they are driving right through the dark, cold belly of a mountain range that has stood for millions of years, while listening to the radio and sipping lukewarm tea. The sheer engineering willpower required to blast through longest tunnels in India, dealing with freezing temperatures and unpredictable water channels just to connect two isolated worlds, is extraordinary. It changes the entire rhythm of travel.
With Kashmir’s Zojila Road Tunnel nearing completion, the whole game is changing for wanderers heading up north by securing cheap flights to Kashmir. No more waiting out massive blizzards or watching the calendar to see if the pass is open. It is pure, uninterrupted access to some of the most jaw-dropping landscapes on earth.
