6. Wildlife safari at rajaji national park

Rajaji National Park, located in close proximity to Dehradun, is a haven for wildlife enthusiasts and adventure seekers. Rajaji is essentially an elephant sanctuary with some big cats. There are a few tigers but are the cats that are relatively easy to spot. Also sharing the habitat are spotted deer, cheetal, and barking deer, which can be seen frolicking on the banks of Ganga, and the Himalayan black bear, sloth bear, and grey langur, which prefer spending their days in the trees. Big mammals aside, the park is a delight for birdwatchers due to its varied habitats. As many as 315 bird species can be found at Rajaji. The rare great pied hornbill, with its fluttering eyelashes and distinctive helmet of yellow and black, is often seen here. During the breeding season between January and April, a glorious chorus, initiated by the male and later harmonised with its female counterpart can be heard resonating throughout the forest. Sadly, these impressively colourful birds are classified as near threatened due to hunting and loss of habitat. Look out also for the Indian grey hornbill, woodpecker, black-necked stork, green bee-eater, Egyptian vulture, yellow billed blue magpies and snowy-browed flycatcher as well as the entertaining aerobatic displays of the Indian roller. The park is open from 15 November to 15 June, and remains closed during the rainy season. The best time for birdwatching is in winter (November to February) as migratory birds descend in large numbers. May and June are the best times for photographing the wildlife, but it is extremely hot and dry, with temperatures soaring to approximately 48°C.
