Gangotri, Yamunotri, Kedarnath, and Badrinath are part of the Chota Chardham circuit, which was established by Adi Shankaracharya in the eighth century. The months of April to the first part of June are great for visiting Chardham since the weather are pleasant, allowing you to explore the area and travel without suffering chilly feet or chattering teeth. Avoid Chardham during the rainy season, which runs from June to September and is prone to landslides.
