Eravikulam National Park

The air changes first. As the forest department bus climbs the last bends above Munnar, the windows fill with cool mist. It smells of wet grass and crushed leaves. Then you step out onto a narrow road at Rajamalai, and the ground falls away into rolling green hills. Clouds move across them so quickly that a whole slope can vanish and return in under a minute. Listen for a moment. Wind, water, and very little else.

Welcome to Eravikulam National Park, high in the Western Ghats of Kerala. The Western Ghats are a long chain of mountains that runs down India's western side, older than the Himalayas. This park sits on a high plateau in the Kannan Devan Hills, in Idukki district. Most of what you see here is grassland mixed with small pockets of dense forest. It looks gentle. In fact, it is one of the rarest landscapes in southern India.

That mix has a name. Ecologists call it the shola-grassland system. The shola are the dark, compact patches of evergreen forest tucked into the folds of the hills, usually along streams. The open slopes between them are montane grassland, shaped by altitude, frost, and constant wind. The two work together. The grass catches rain and mist, and the shola store it. Many streams that feed rivers in Kerala and Tamil Nadu begin in hills like these.

Now look along the rocks beside the road. With luck, you will see a stocky, goat-like animal with a coarse brown coat and short, curved horns. This is the Nilgiri tahr, a mountain ungulate found only in the Western Ghats. Ungulate simply means a hoofed animal. Eravikulam holds the largest surviving population of this species anywhere. The tahr is also the state animal of Kerala. That is a lot of responsibility for one small plateau.

Here is something many visitors miss. The tahr you see near the road are often calm, almost tame. They graze a few steps from people and barely lift their heads. This is not their nature everywhere. On distant cliffs, wild herds keep their distance and move across slopes that look impossibly steep. The relaxed animals at Rajamalai show what decades of protection can do. Please enjoy them, but do not feed or touch them.

The tahr were not always this safe. Through the nineteenth and twentieth centuries, these hills were tea country, opened up by British planters. Hunting was common. Over time, the planters themselves formed a game preservation association to manage the area, and the land slowly shifted from hunting ground to refuge. Kerala declared Eravikulam a wildlife sanctuary in 1975. It became a national park in 1978. The tahr population has been carefully monitored ever since.

Because the herds matter so much, the park sometimes closes for a period each year while the young tahr are born. Calving is a fragile time, and quiet helps the mothers. If you visit soon after the park reopens, keep an eye out for small kids. That is the word for young tahr. They stay close to their mothers and wobble over the rocks with surprising confidence. It is one of the gentlest sights in Kerala.

Now lift your eyes toward the higher ridges. Somewhere in that skyline is Anamudi, the highest peak in India south of the Himalayas. Its name is usually translated as elephant's head, and from certain angles the broad, rounded summit really does suggest one. Anamudi lies within the park. The public walking route does not climb it. For most visitors, the peak is a presence on the horizon, appearing and disappearing in the cloud.

The second surprise of this place is a flower. Across these grasslands grows a shrub called neelakurinji. For years it looks like nothing special, a low, green bush. Then, roughly once every twelve years, whole slopes bloom together in a soft blue-violet. The last great flowering here was in 2018, and visitors came from across India to see it. In ordinary years, you may find only a few scattered blooms. Locals measure time partly by this flower.

People have lived with these hills far longer than any park boundary. The Muthuvan, an indigenous community of the region, have long made their homes in the forests and valleys around the plateau. Their knowledge of the land, its plants, and its animals runs deep. The park today depends on that wider web of people. Forest guards, local guides, and nearby communities all play a part in keeping the tahr and the grassland intact.

Your own visit follows a simple path. Private vehicles stop at the lower gate, and forest department buses carry visitors up to Rajamalai. From there, a paved walking road leads along the hillside. It is not a hard climb, but the altitude and the slope can tire you more than you expect. Walk slowly. Stop often. The views open up best when you turn around and look back the way you came.

Weather shapes everything here. In the monsoon months, rain sweeps across the plateau in grey curtains, and the streams turn loud and white. In the cooler, drier season, the sky can be sharp and clear, and the grass turns gold at the edges. Mornings are often the clearest. By midday, cloud may roll in from the valleys and swallow the hills. Each version of the park is different, and each one is worth seeing.

Before you leave, stand still for a minute. Feel the cool wind on your face and the damp in the air. Look at the dark shola tucked into the valleys below, and the long green slopes above them. Watch a tahr move across the rock without hurry. As the bus carries you back down toward the tea gardens, notice how the forest closes in and the air grows warm again. You are leaving the high country behind.
