The Rohtasgarh Fort in Sasaram, Bihar is a historical fortress located on the top of a hill offering picturesque views and a journey through India's rich heritage. The best time to visit the fort is during the post-monsoon months and the winter season, which extends from October to March. During this time, the weather is pleasantly cool and the skies are clear, offering a perfect backdrop for exploring the vast expanses of the fort without the fatigue caused by the scorching heat which is common in the summer months.
Tourists should ideally target the months between November and February, when the temperatures range from a comfortable 10°C to 25°C. This period not only provides a comfortable climate for roaming around the extensive grounds of the fort but also coincides with several major Indian festivals like Diwali, and Makar Sankranti, providing travelers with an opportunity to experience the local culture and festivities. Visitors should, however, avoid the summer season, especially April to June, when temperatures can soar up to 40°C, making day trips quite challenging.
