Kochi to Munnar and down to Alleppey

Kochi to Munnar is about 130 km and takes four hours, and the disagreement between those two numbers is the whole character of the drive. As far as Kothamangalam you are in flat, wet, built-up Ernakulam and the road belongs to buses. The trip actually begins at Neriamangalam, where NH 85 crosses the Periyar on an arch bridge opened in March 1935 and still called the gateway to the high ranges. Above it the road climbs roughly 1,500 metres in 45 kilometres of hairpins, and two waterfalls, Cheeyappara and Valara, arrive a kilometre apart directly beside the carriageway. Munnar sits at 1,600 m where three streams meet, which is what the name says in Malayalam. The town itself is a traffic jam with tea around it, and the sightseeing points that every itinerary lists — the echo point, the photo point — are car parks with a view. What is worth the drive is Eravikulam, thirteen kilometres north, where Nilgiri tahr graze the Rajamala slopes and Anamudi stands behind them at 2,695 m, the highest peak in India outside the Himalaya. You are taken up by park shuttle; private cars stay at the base. Then you come back down the same ghat and keep going, and over 175 km the country changes completely — tea, then rubber, then coconut, then paddy and standing water. It ends on Vembanad at Alappuzha, and the last day of this trip is spent not driving at all.

NH 85 is a hill road that exists because of tea. The Kannan Devan Hills were opened to planting in the 1870s and 1880s, and everything above Adimali — the estates, the tramway that once ran to Top Station, the bungalows on the ridges — was built to get leaf down to the plains and labour up to the slopes. The Neriamangalam bridge of 1935 was the piece that made the whole thing a road rather than a track, which is why a bridge gets a nickname usually reserved for a pass.

The 1935 arch bridge at Neriamangalam, Cheeyappara and Valara falling beside the road, the Nilgiri tahr at Rajamala with Anamudi behind them, the Top Station road past Mattupetty, and the descent from tea through rubber and coconut to water.

Two roads in one. As far as Kothamangalam it is flat, wet, continuously built-up Ernakulam — rubber, bus stops, a town every few kilometres, and slow going that has nothing to do with the surface. Above Neriamangalam it becomes a hairpin ghat cut into forested slope, climbing about 1,500 m in 45 km. The ghat is being widened, and the cutting has made the slopes unstable. A landslip at Adimali in October 2025 buried houses below the road and closed the highway for five days. Expect single-lane working, expect to be stopped, and do not plan a tight connection around this stretch.

Do the climb in the morning and the descent before dark; the ghat holds mist from mid-afternoon and the lorries do not slow down for it. Cheeyappara and Valara arrive about a kilometre apart on the left as you climb, directly beside the carriageway — there is no turning to look for and no detour to make, which is why most people drive past both and realise afterwards. Coming down, use engine braking. The long continuous descent from 1,600 m is where brakes overheat, and this road has killed people that way. If you are aiming for Eravikulam, the gate takes visitors from 8 a.m. to 2 p.m. An afternoon arrival in Munnar means you are not going that day.

ERAVIKULAM IS SHUT 1 FEBRUARY TO 31 MARCH, every year, for the Nilgiri tahr calving season, on the order of the Chief Wildlife Warden. It reopens on 1 April. Those two months are also Munnar''s clearest, driest, most photogenic weather and peak domestic holiday season, which is exactly why people keep arriving to find the one world-class thing here locked. If your dates are fixed in February, plan a tea-and-driving trip and do not build the days around the park. Gate hours are 8 a.m. to 2 p.m. Entry is Rs 200 for Indian adults and Rs 500 for foreign nationals, with camera fees on top. Only the Rajamala tourism zone admits visitors; the park is 97 sq km and the rest of it is core and buffer. On the kurinji: Neelakurinji flowers once in twelve years. The last mass bloom around Munnar was 2018 and the next is expected in 2030. There is no annual kurinji season, whatever a hoarding tells you. On houseboats: Kerala Tourism classifies them Silver, Gold or Diamond, and the classification is worth checking rather than the photographs. Boats do not cruise after dark. Check-in is around midday, which is the constraint that breaks three-day versions of this trip — you cannot leave Munnar after breakfast and make a noon boarding 175 km away. On season: September to January is the window. The tea is greenest after the monsoon, the ghat waterfalls still run, and the park is open. June to August is the southwest monsoon, when the falls are at full volume and the ghat is at its most dangerous. Late August is when Alappuzha runs the Nehru Trophy on Punnamada — the 72nd edition was held on 22 August 2026 — which is a reason to accept monsoon risk on purpose.
