Driving the Munnar ghat road in monsoon

June to September, the road from Kochi to Munnar becomes a different road. Not a dangerous one — but not one to take casually, and not one for a driver seeing it for the first time.

We run it every week through the monsoon. Here is what it is actually like.

Where the road changes

The first 60 km, Nedumbassery through Perumbavoor to Kothamangalam, is ordinary wet-weather driving. Flat, four lanes in places, decent drainage. Rain slows it a little. Nothing else.

It changes at Neriamangalam. The bridge there is where the climb starts, and from that point to Adimali you have about 25 km of ghat road with the Periyar on one side and cut rock on the other.

This is the stretch that matters.

The three things that actually happen

Water across the road

Common, undramatic, and the thing people worry about least when they should worry about it most.

After heavy rain, water sheets across the road at the same handful of points where streams cross above. It is usually ankle-deep and moving. The danger is not depth — it is that it hides potholes and it is running.

The way to drive it is slowly, in one gear, without stopping in the middle. Every driver who works this road knows the specific corners. A driver who does not will find them at speed.

Landslides

The one that closes the road. Most years it happens at least once, typically between Neriamangalam and Adimali, usually after several consecutive days of heavy rain rather than one big storm.

What it looks like in practice: earth and rock across one or both lanes, cleared by the PWD in anything from four hours to two days.

There is an alternative. Munnar can be approached from Kothamangalam via a longer inland route that adds about an hour. We take it when the main road is closed or looking marginal. It is not a secret — every local driver knows it — but a driver from outside the district often does not.

Fog on the top section

Above Adimali, from roughly 1,200 m, cloud sits on the road. Visibility drops to twenty or thirty metres and stays there.

This is why we care so much about arrival times in monsoon. Fog plus dark plus hairpins is three problems at once, and the only one you can control is the third.

How much longer it takes

Conditions	Journey time
Dry season	3 hrs 30
Ordinary monsoon day	4 hrs
Heavy rain	4 hrs 30
Landslide diversion	5 hrs

We do not charge extra for any of it. The fare is the fare. What we do instead is leave earlier — if the forecast is bad we will ask to move your pickup forward, and it is worth saying yes.

What we will and will not do

We will drive the ghat road in heavy rain in daylight, with a driver who runs it regularly, at a speed that suits the conditions.

We will not start the climb after dark in heavy rain with a full car. If your flight lands at 9pm in July, we will suggest a night in Kochi and a 6am start.

That costs us the evening run and costs you a hotel night. We suggest it anyway, and we would rather you booked someone else than argued us into it.

If you are driving yourself

Some people hire a self-drive car. If that is you:

• Go in daylight. Not negotiable in monsoon.
• Check the road before you leave. Local news or the hotel will know about closures. Google Maps will not — it routes you into closed roads cheerfully.
• Fuel at Adimali. Last reliable pump before the top.
• Use engine braking on the descent. The hairpins coming down from Munnar will cook your brakes if you ride them for 25 km. This is the single most common mistake and it is how people end up in trouble.
• Do not stop on blind corners for photographs. Obvious, and it happens constantly.

Is it worth coming?

Yes, with a caveat.

Monsoon Munnar has mist moving through the tea at eye level, Cheeyappara at three times its dry-season volume, empty viewpoints and rooms at half price. The green is a colour the dry season never produces.

The caveat: give it three nights minimum. Two nights with one washed-out day means you drove eight hours to see cloud. Three nights and you will get at least one clear morning, and that morning will be better than anything February gives you.
