On the outskirts of Jaisalmer in the arid state of Rajasthan lies the filled to the brim Gadisar Lake like an oasis in the heart of a desert. Back in the middle ages, there were no canals or irrigation system or other scientific methods to bring water to the arid regions of Rajasthan. This reservoir was built by Raja Rawal Jaisal keeping in mind the need of his people. Located pretty close to the fort of Jaisalmer, the lake is frequently visited by travellers from all around India as well as foreigners. Gadisar Lake offers scenic views from all sides of the lake, especially when the eastern sky is blood red and the sun rises, striking its rays on the top floors of Jaisalmer Fort.
