The Rajgir Hot Springs, locally known as Brahmakund, are a year-round destination for pilgrims and tourists seeking the therapeutic and spiritual benefits attributed to their warm waters. However, the best time to visit Rajgir Hot Springs is typically between October and March when the weather is relatively cool and pleasant. During these months, the climate in Rajgir is moderate with temperatures ranging from 20 to 28 degrees Celsius (68 to 82 degrees Fahrenheit), which is ideal for taking a comfortable dip in the hot springs and exploring the surrounding attractions without the intense heat of the summer months.
Visiting in the cooler months also allows travelers to partake in other activities in Rajgir, including sightseeing at the historic sites such as the Vishwa Shanti Stupa (Peace Pagoda), the ancient Nalanda University ruins, and the Rajgir Wildlife Sanctuary. Moreover, these months coincide with several local festivals and events, including the vibrant Rajgir Mahotsav, usually held in December. However, it's worth noting that weekends and national holidays can attract larger crowds, so if you prefer a more peaceful experience, consider a weekday visit. While the springs are accessible throughout the year, it is advisable to avoid the monsoon season (June to September) due to the high humidity and potential rain-related disruptions.
