The best time to visit Kasol is different for different people. If someone wants to witness the beautiful Parvati valley completely covered with snow then the perfect time is around December to February. Summers in Kasol is when the tourist season kicks in for stays. The days are warm, but not as uncomfortably hot as the rest of India, and it is the perfect time to go sightseeing to the enormous number of attractive tourist spots here, or indulge in adventure sports like trekking to get your adrenaline going. This is the time when tourists throng to the place so you may like to complete your hotel booking well in advance.
Monsoons in Kasol are for tourists who are willing to stretch their definition of comfort a bit. That being said, although Kasol is beautiful like always, it is not a good time to make a visit to it now. As with all hilly regions, the land turns unsafe and uncommunicative as landslides and natural disasters are common, and sightseeing is dampened to almost nil by rains. Adventure sports are out of the question as well and another potential danger source is the chance of cloudbursts. Winters in Kasol shouldn’t be visited if you are not intensely interested exclusively in watching the snowfall. The winters are harshly, bitingly cold and people may face physical discomfort. It may be too cold to go sightseeing or perform outdoor activities. On the upside, you can book tickets at your leisure because the place isn’t really crowded at this time of the year.
