Banaras Hindu University is one of the oldest universities in India, and it is named after Lord Vishwanath. It has a sprawling campus with beautiful gardens, temples, and museums. The main attraction is the Bharat Kala Bhavan Museum, which houses a vast collection of Indian art, textiles, and crafts. If you have children, take them to the Children's Science Museum, where they can learn about science in an interactive way.
Sarnath is a sacred site for Buddhists, as it is where Gautama Buddha gave his first sermon after attaining enlightenment. The main attraction is the Dhamekh Stupa, which is said to mark the spot where the Buddha spoke. There are also several temples and monasteries in the area, as well as a deer park and a museum. If you're lucky, you might even spot some monks practicing meditation.
A boat ride on the River Ganges is a must-do when in Varanasi, and it is especially fun for children. You will get to see the ghats (steps leading down to the river) where locals come to bathe and perform religious rituals, as well as several temples and palaces along the river banks. Make sure to time your boat ride for sunrise or sunset, as the colors of the sky are particularly beautiful at these times.
Kashi Vishwanath Temple is one of the most important Hindu temples in India, and it is dedicated to Lord Shiva. It is located in the old city of Varanasi, and it is a popular pilgrimage site. The temple has a stunning architecture and is decorated with gold and silver. Children might be interested in hearing about the temple's history and stories of Shiva from the priests or guides.
If you have more time, consider visiting the Ramnagar Fort, a beautiful palace on the other side of the river. You can also take a walking tour of the old city to see the narrow alleys and markets. If you have less time, you can skip Sarnath and spend more time exploring the ghats and temples in Varanasi. Make sure to wear comfortable shoes and carry a sun hat and sunscreen, as it can get very hot and crowded during the day.
