Visiting Himachal This May? Avoid These Routes to Keep Your Trip Smooth

May is the peak of the “heat escape” season, but 2026 has brought a series of Western Disturbances that have made mountain travel unpredictable. To ensure your itinerary doesn’t end in a 10-hour traffic jam or a closed mountain pass, follow these strictly vetted route advisories.

1. Manali & Lahaul

The Situation: While the Atal Tunnel has revolutionized access, the stretch between Manali and Gulaba is facing heavy pressure.

• What to Avoid: Driving toward Rohtang Pass on Tuesdays. The District Administration of Kullu has maintained a strict “No-Go” policy for all tourist vehicles every Tuesday for essential road maintenance and debris clearance.
• Sourced Advice: According to recent reports in The Tribune, tourist vehicles are currently being restricted at Marhi due to lingering snow accumulation and narrow road width beyond that point.
• The Smooth Route: Stick to the Kiratpur-Manali National Highway. It is now a full four-lane stretch, but leave Chandigarh before 4:00 AM to avoid the heavy tourist bus convoys that peak around 9:00 AM.

2. Spiti Valley

The Situation: You can see the snow, but you cannot cross it yet.

• What to Avoid: The Manali-Kunzum-Kaza road. BRO (Project Deepak) has confirmed that while snow clearing is at its final stage, Kunzum Pass (14,931 ft) is still officially CLOSED to civilian traffic. Any Google Maps suggestion showing this as a “shorter” route is currently incorrect and will lead to a forced U-turn at Gramphu.
• The Smooth Route: You must enter via the Shimla-Kinnaur (NH-5) route. It is longer, but it is the only legal and physical way into the valley right now.

3. Kinnaur

The Situation: Recent IMD Shimla bulletins have issued an Orange Alert for the Kinnaur and Lahaul-Spiti districts due to forecasted hailstorms and lightning.

• What to Avoid: The Nigulsari and Tranda Dhank stretches after 5:00 PM. News reports from Hindustan Times have highlighted increased “shooting stone” incidents in these specific zones during evening rain showers.
• The Smooth Route: Plan your transit through Kinnaur between 8:00 AM and 2:00 PM when the weather is typically stable.

4. Shimla

The Situation: Shimla was recently ranked as one of the “Most Welcoming Regions” in the world for 2026, leading to record-breaking footfall.

• What to Avoid: The Kalka-Shimla NH-5 on Friday evenings and Sunday afternoons. Traffic snarls at Parwanoo and Solan are currently lasting up to 3 hours.
• The Smooth Route: If your destination is Narkanda or Upper Shimla, take the Shimla Bypass via the Apple Cart Inn road to avoid the city center entirely.

5. Dharamshala

The Situation: The Kangra administration has implemented strict “One-Way” traffic to manage the May surge.

• What to Avoid: Driving a private car into the McLeodganj Main Square. Local news outlets have reported that police are frequently diverting private cars to lower parking lots 3km away.
• The Smooth Route: Use the Dharamshala-McLeodganj Skyway (Ropeway). It’s a 10-minute trip and bypasses the entire uphill traffic jam.

6. Dalhousie & Chamba

The Situation: The Jot Pass connects Chamba to Dalhousie, but it is currently treacherous.

• What to Avoid: The Jot Road during rain. Jagran recently reported multiple vehicles skidding on this route due to unseasonal hail accumulation on the sharp bends.
• The Smooth Route: Stick to the Pathankot-Banikhet highway. It is better surfaced and handled by the PWD more frequently during weather events.

Summary of Sourced Advisories (May 11-15, 2026):

• Weather: Orange Alert for hailstorms and lightning in Kullu, Mandi, and Shimla (IMD Shimla Press Release, May 11).
• Road Closures: Rohtang road closed every Tuesday for maintenance (DC Kullu Official Order).
• Spiti Access: Only via Kinnaur; Kunzum Pass remains snowbound (BRO Status).

The mountains are calling, but in May 2026, they are also demanding respect. With the IMD’s Orange Alert in effect and the BRO still battling 20-foot snow walls at Kunzum Pass, the secret to a successful trip isn’t just a fast car—it’s real-time information. By choosing the safer NH-5 route through Kinnaur and timing your transit to avoid weekend bottlenecks in Shimla and Manali, you can stay ahead of the crowds and the chaos. Preparation is the difference between a nightmare in a traffic jam and a serene mountain escape. So, as you finalize your bags and prepare for your Himachal trip from delhi, keep these verified road statuses bookmarked to ensure your journey is as smooth as the view from the top.
