Tourists getting down from a mini-bus inside the Eravikulam National Park. Once the bus reaches its final point, tourists can climb the winding road that climbs up the hillside (as can be seen with tourists at a higher point at the path) to go to higher locations in the park. A fog or mist is rolling down the hillside, to be followed by rain soon after. These are grasslands, with grass and the occasional trees. Eravikulam National Park is a relatively small national park located in the Idukki district of Kerala, being a part of the Western Ghats. Small because the area of the park is 97 sq. km, while traditionally the sanctuaries located in other parts of India can be many hundreds of sq. km or more. The park is interesting to visit, since it is located at a higher altitude, with the park being located at a height of around 2000 meter, on a hill plateau. The park has a number of animals, the most famous inhabitants of the park being the endangered Nilgiri Tahir (Nilgiritragus hylocrius) with a number of different predators also being found in the area. The park has 3 different regions of greenery - forests in some of the lower sections, grasslands and shrublands (located at higher levels and in rocky areas). Visitor vehicles are not allowed inside the park, with entry into the park being through mini-buses that are run by the park authorities. These buses take the visitor to a higher point, and from there visitors can climb higher on the turning and winding road and even come into contact with the Nilgiri Tahir who come close to the road.
