In fact, looking at the weather and the sky from Darjeeling Town is almost no indication of how the weather might be at Tiger Hill. Cloud and fog in this area lie at various levels of the mountains, some times they may be above you, other times you may be above them. So no one can guarantee a perfect sunrise view from Tiger Hill or for that matter from anywhere in Darjeeling.
Once you reach the top of the observation tower, you have access to an almost 360-degree view of Darjeeling. The sky is still dark at first; the first rays of sunlight slowly begin to brighten the sky and redden the visible peaks of Kanchenjunga. There are five peaks of Kanchenjunga, the highest being about 28000 feet high, making it the third highest peak in the world. As the sun rises, the colour of the rays on the peaks changes as well, ranging from red to orange to gold and then to white.
There are over 86 tea estates in Darjeeling that are responsible for producing the worldwide famous 'Darjeeling Tea'. Have a cup of locally brewed chai at the tea estate, or get down amidst the plantations to pluck a few tea leaves yourself, you are free to take your pick!
Don't discount Darjeeling Zoo as yet another typical one that you see in a city. This is where you can actually see some of the high altitude amazing Himalayan animals and some endangered species that are rarely seen anywhere else in the world. In India, this is the largest high altitude zoo. It spans across 67.5 acres of area at an average altitude of 7,000ft (2133m). Some of the highlights of the zoo includes Tibetan Wolf, Red Panda, Snow Leopard etc all in semi natural habitats.
