Eravikulam National Park is one of the most beautiful protected areas of Kerala. It is one of the last strongholds of the Nilgiri tahr, a critically endangered mountain goat. The park is also home to the neelakurinji or Strobilanthes kunithianus, a shrub that flowers only once in twelve years. Both this flower and the Nilgiri tahr are in the tourist zone of the park, Rajamalai, which is open to tourists. While planning your trip to Eravikulam, do remember that the park remains closed for 2 months during the calving season of the tahr in April-May every year. The other national parks around Munnar include the Pambadum Shola National Park, Mathikettan Shola National Park and the Anaimudi Shola National Park.
