I have just returned from my trip to India, on behalf of my summer friend’s invitation. John did his best to make my staying at their home pleasant. John‘s family was very hospitable and his younger brother Jigs had a very good sense of humor.Indian People are most friendly and welcomed people Also, there are a lot of interesting and magnificent Indian places to visit.
As I am interested in history we decided to go around Delhi. We took metro , then, rent a car to make our trip easier and more comfortable. we visited some interesting places. One of the most beautiful ancient buildings was the red fort. It was beautifully built with red marbles. it was made by the mughals who ruled India.
In Delhi, you can also find out a number of temples, the most beautiful , which is the lotus temple shaping like a lotus. Also, there are lots of museums which sound us about the ancient ruins of India like the national museum. There are also many universities and educational institutions in Delhi. We climbed mountain called Nanda Mountains.
There are plenty of restaurants of different prices and good service ,
In short, it is very beautiful city and hope to visit it in the near future
