The popular 'tourist season' is between October and February when the weather is pleasant and not too hot. However, the best time to visit the Himalayas is between April and June. Once the monsoon season (between July and September) commences, these parts are prone to landslides. In winter the higher reaches of these mighty mountains often get snowbound. Wildlife enthusiasts swear that the hot months of April and May are the best for game viewing. This is because the smaller water holes inside the national parks, reserves and sanctuaries dry up and the wild animals tend to congregate around the larger ones. While most of the wildlife parks are closed during the monsoon months (July to September), the one in South India remains open right through the year.
