The best time to book the Karnataka package is from October to April. Winters are ideal for going on a wildlife safari or attending the majestic Mysore Dasara. Karnataka is quite warm and moist during the summer months of April to June due to its proximity to the western coast. While the coasts are hotter, hill stations are mildly colder. In fact, the perfect time to visit Karnataka is determined by the time of year and the destination. Some areas experience heavy rainfall during the monsoons, which runs from July to September, but if you would like to go trekking in places like Antara Gange or see the wonderful Jog Falls, there's no better time than the monsoons.
