Manali to Sissu to Darcha Road Trip via Atal Tunnel: Complete 2026 Travel Guide
Manali to Sissu via the Atal Tunnel is a short Himalayan road trip of about 40 km that takes roughly 1–1.5 hours in normal conditions. Travellers often extend the drive to Keylong or Darcha on the Manali–Leh Highway. The route is accessible most of the year, though snowfall and BRO advisories can affect conditions, especially between December and March.
The drive from Manali through the Atal Tunnel into Lahaul Valley has quickly become one of the most scenic short Himalayan road trips in North India.
Before the tunnel opened, reaching Lahaul required crossing Rohtang Pass, which was often closed due to snow. Today, the Atal Tunnel provides an all-weather link between Kullu Valley and Lahaul, allowing travellers to experience snow landscapes, frozen rivers, waterfalls, and high-altitude villages within a few hours of Manali.
The route typically follows this order:
Manali → Atal Tunnel South Portal → Atal Tunnel North Portal → Sissu → Tandi → Keylong → Jispa → Darcha
This drive forms the first section of the larger Manali–Leh highway journey.
