Delhi to Shimla
by Car

350 km by road, and 7-8 hours behind the wheel. The route divides into 5 stages, the longest being Delhi to Karnal at 130 km. The longest stage is not the slowest one: Pinjore to Solan covers 60 km in 2 hrs, which is where the hours actually go.

Pinjore to Solan — 60 km graded moderate, and 2 hrs of the day. Mountain ghat begins at Kalka, 22 hairpin bends. By contrast Karnal to Ambala is graded excellent, so the route is not uniform and planning it as one average speed is how people end up arriving after dark. The road quality on this corridor runs across excellent, good and moderate.

Pinjore to Solan — 60 km in 2 hrs, which is the slowest average on the route. Mountain ghat begins at Kalka, 22 hairpin bends. Delhi to Karnal is the longest stage at 130 km and takes 2 hrs, so distance and time are not in proportion on this corridor. Knowing which stage is slow is what lets a departure time be chosen properly rather than guessed at.

NH-44 expressway, smooth 6-lane road, GT Road heritage stretch, Pinjore Gardens worth a quick stop and Mountain ghat begins at Kalka, among others. These are on the route rather than detours from it, which is the practical distinction — a stop that costs you ten minutes is a different proposition from one that costs an hour each way. Tell the driver in advance which of them you want to stop at and the day gets planned around it instead of around the clock.

Stop at Barog for chai — the old railway tunnel nearby is a heritage attraction. Then: carry motion sickness pills — 22 hairpin bends after Kalka can be nauseating. Then: use lower gear on mountain descents — brakes overheat on the 30 km ghat section. Then: leave Delhi by 5 AM to enjoy the Kalka-Shimla mountain stretch in daylight. None of that is generic road-trip advice — it is what the drivers who run this corridor pass on, and the position-specific items are the ones worth reading twice.

The mountain work on this route is a different job from the highway part of it, and we treat it that way: a driver who knows this climb goes on this run. Pinjore to Solan is the stage that asks the most of the car and the driver. Lower gears on the descent rather than the brakes, a wider following distance than feels necessary, and a start early enough to finish the climb in daylight.

We would rather you did not, and we will say so. The hill section of this route is the part where visibility, unlit edges and oncoming traffic combine badly, and arriving three hours later in daylight is the better trade. If the journey has to run into the night, it runs with the night allowance for the driver and a start time chosen so the climb is behind you before dark. A driver asked to do 350 km on no sleep is the single worst risk on any booking, and we do not take it.

Murthal Dhabas at 40 km, Ambala at 200 km and Barog at 280 km. Those figures are measured from Delhi, not from Shimla — the same stops on the return journey sit at different numbers, and a list copied from the other direction puts every one of them in the wrong place. The useful halfway mark on this route is around 175 km.
