In 1900 the Kundale Road and Tramway between Munnar and Top Station was completed by the Kanan Devan Hills Produce Company. The 35 kilometres (21.7 mi) road runs down the valley of the Kundale River. The road was built 4.6 metres (15.1 ft) wide of which 3.7 metres (12.1 ft) was metaled. The sharpest curve was 20 metres (65.6 ft) and the steepest gradient was 1 in 30. There were 22 timber bridges between 7.6 metres (24.9 ft) and 20 metres (65.6 ft) span. By 1905 the timber bridges were being replaced by steel and concrete structures.

In 1942, during World War II, Madras City  was bombed by the Japanese but the physical damage was negligible, though the public response was major and the city was evacuated because of fears of subsequent Japanese bombing and invasion. Many rich families from Madras moved permanently to the hill stations in fear.
In 1942 in preparation for a possible Japanese invasion of India, the British began improvements to the road to facilitate its use as an evacuation route from Berijam Lake

Beyond km marker 13 on the Berijam road there is a firewatching tower from where one may have a fine view of the secluded Berijam Lake and the surrounding forest.
At km 21 at 2180 metres (7,152.2 ft) elevation, Berijam has a Forest Department Camp including an Eco-Education Center for visitors. Nature areas to be visited here include: swamp ecosystem, fresh water ecosystem, nature trail, bridge, medicinal demonstration garden, museum, nature walk, grassland and shola. This camp also is the site of an old two-story brick building, partly damaged and blackened over the years, with a bright yellow painted name reading "Britisher's Transit Camp". This is one of several transit camps built during World War II for British soldiers to rest along the 230 km (143 mi) British “Escape Route” from Kodaikanal via Top Station and Munnar to Cochin. While most of the transit camps are now either dilapidated or demolished, the one at Berijam is still used as a Forest Rest house. At this point an old road, now just a trail, forks off to the north for 12 km (7.5 mi) down to Kavunji village at 1975 metres (6,479.7 ft) elevation.

West of Berijam Lake, the road is closed for public vehicles and not maintained. Though the road is heavily damaged and overgrown till the Kerala border, it is well maintained within Kerala past Top Station.

The road meanders southwest and passes south of Konalar Dam and reservoir at km 25. It then continues southwest and around the south side of a 2320 metres (7,611.5 ft) hill at km 31, then northwest around 2517 metres (8,257.9 ft) Ibex peak and through a shallow 2390 metres (7,841.2 ft) pass at km 34. 1.5 km over a hill past a rest house, it passes down across a bridge over Kathirikkai Odei (the Second Trout Stream). There is a path from there up along the stream to a waterfall on the stream. The road then proceeds northwest, bridges the Pulavachiar river at km 39, makes a loop north and then passes south along the east side of Vandaravu Peak. The road crosses its highest point of 2480 metres (8,136.5 ft) just south of Vandaravu Peak at km 50 where it crosses the Kerala state boundary and enters Pampadum Shola National Park

A pamphlet, "Sholas For Survival", available from the District Forest Office, Kodaikanal describes 17 local treks ranging from leisurely walks to challenging day long treks. This booklet provides a trekking map of the Palani Hills and details the degree of difficulty for each trek.

Shelters

There are several structures on or near the road which may be available for overnight use by trekkers. Proceeding east to west, they are:
  • The Forest Dept. checkpost at 10°12′39"N 77°26′53"E near Muir Point after Km 9 is not for overnight use but may offer temporary daytime shelter during a rain shower.
  • Green Hut is an old Forest Dept. bungalow at 10°11′50"N 77°26′06"E near km 14, which has been used for overnight camping since at least 1943. It will be renovated soon.
  • The Fire lookout tower at 10°11′32"N 77°25′11"E just past km 13, 8 km (5 mi) before Berijam lake, has a roofed hexagon structure not meant for overnight use but can offer short term safety from Gaur and elephants.
  • There is a Forest Rest House at Berijam Lake, first developed as a British Transit Camp, at 10°10′54"N 77°23′20"E, at km 23, with limited accommodations, which serves as an overnight base camp for Forestry Department staff, researchers and trekkers. Trekkers must get advance permission to stay overnight there. Visitors must bring their own provisions, but cooking facilities are available.


  • There are two huts at a place variously called Marian Shola Bungalow and Sebastian Camp on a trail south of the road at 10°8′47"N 77°20′38"E. These are shown on the Army map. The bungalow there was fixed up several years ago and equipped with flush toilets and an elephant ditch was built around it. There is a separate kitchen building out back.
  • There is a Forest Department Hut and other Forest Department buildings at 10°8′56"N 77°20′9"E at the first trout stream. Tamil Nadu Forest Dept. built the buildings to house Dept. staff who lived there while supervising wood cutting enterprises and road work crews. The laborers, mostly Sri Lankan Tamils, built temporary shacks of poles and matting. The shacks were abandoned when the cutters moved on to another area. The supervisors' "pucca" huts remain and now provide basic overnight shelter for trekkers. Limited overnight accommodations may be used with advance permission.
  • Pulavachiar Forest Quarters is an old British Transit Camp at 10°9′56"N 77°17′42"E, near mile stone: "Top Station 12". This camp shows below a red star on the Army map. There is overnight shelter here for trekkers.
  • Vandaravu camp is two structures at 10°9′26"N 77°16′26"E on the north slope of Vandaravu Peak, as shown on the 1959 Army Map. Current condition and suitability for shelter is unknown.
  • There is a small corrugated steel shelter on the lower square platform of the observation tower at Pampadum Shola National Park

This shola/grasslands ecosystem was effective in conserving monsoon rainfall and letting it soak in to replenish the watertable for year round release into the streams.

 already taking over the grasslands around the road. A detailed dynamic map of 2002 vegetation shows distribution of various plantation species that have replaced most of the grasslands and native evergreen forests. Another 2002 map of Palni Hills, showing distribution of wattle plantations, also shows wattle dominating the route of the Kodaikanal Munnar Road. Exotic forests now cover over 80% of the area which was previously covered by Grasslands. These non-native species now dominate thousands of acres once dominated by native grasses.

These extensive wattle plantations are sometimes blamed as the major cause of reduced soil moisture and stream flows across upper Palni catchments, though it is likely that reduced rainfall during the Southwest monsoon period, combined with a pattern of heavy downpours and longer dry spells between rain events in the non-monsoon months is also responsible. Wattle plantations in the upper Palanis seem to help regrowth of indigenous shola species and associated wildlife, and also reduce cutting of shola forests by providing superior fuel wood. It is probable that these old, non-productive plantations, that are slow-growing or partially invaded with native woody species, are similar to native forest in terms of water use.

New route

Though the old evacuation route is now impassable for vehicles, there remains a desire and need among farmers and tourists for a direct road link between Kodaikanal and Munnar.

The Kadaveri– Kilvari road is a horse trail used by farmers of Kadavari to take their products to Kodaikanal, via Kilavarai. It is possible but not practical to pass here by off-road vehicle

.
Straight line distance from Kadaveri to Kilvari is 5.9 km (3.7 mi). The new route is 14.6 km (9.1 mi).

This is the least improved section of a new Munnar–Kodaikanal Highway proposed by the Roads and Bridges Development Corporation of Kerala Ltd. This highway would provide a direct road link between the two popular hill stations of Munnar and Kodaikanal. The proposed road connects Vattavada (near Munnar) and Kadavari at the Kerala–Tamil Nadu border. Length of the proposed Vattavada - Kadavari Road is 22.37 km (13.9 mi) A 4.5 km (2.8 mi) extension of the above road from Kadavari to Kilavari in Tamil Nadu is also proposed.

The proposed road would reduce the travel distance between the two hill stations 41% from 198 km (123 mi) (via Kodaikanal – Perumal Malai
