Fateh Sagar Lake is an artificial lake in Udaipur named after Maharana Fateh Singh. It is said to be the pride of the city of lakes. It is located in the north of the Pichola lake. It lies just beside the entrance to Moti Magri Hill. Fateh Sagar Lake is well planned with three intake channels. It is embellished by three small islands which can be reached by taking a boat ride in the lake.

The largest island is developed into a park by the name of Nehru Park. The garden comprises a boat-shaped restaurant and a zoo for children. This island is the favorite picnic spot in Udaipur. The second island is converted into a public park with great water jet fountains. The third island is called Udaipur Solar Observatory, which is the best solar observing site in Asia. You can also hire pedal boats or motor boats to enjoy a boat ride in the lake. Every year a festival called the Hariyali Amavasya Mela is organized at the lake precincts, in the month of Shravan.
