Cheshmeh Gilas

Cheshmeh Gilas is one of the most important natural and historical attractions of Razavi Khorasan Province. It lies in the village of Cheshmeh Gilas, about 50 kilometres northwest of Mashhad. The spring is located at an altitude of more than 1,000 metres above sea level, in an area between the different levels of the Tus and Mashhad plains, which gives it distinctive hydrological characteristics. The spring is about 4 to 5 metres deep, its discharge is estimated at about 230 litres per second, and it is classed as a karst (limestone) spring. Its special geographical position and permanent flow have made the area around the spring a green, cool and very delightful setting for travellers.

Besides its natural value, Cheshmeh Gilas has a considerable history, and in ancient texts it is also known as "Golsab". According to historical accounts, efforts were made in different periods to bring the spring's water to Mashhad and even to run it through the Holy Shrine of Imam Reza (AS). The first attempts were made in the Timurid era by Amir Alisher Navai, and later in the Safavid period, part of the project was realised under Shah Abbas the Safavid. Because it flows constantly and always gushes strongly, the spring has never dried up at any time of year, and this has made it one of the most notable and valuable springs in eastern Iran. Small natural pools and ponds have also formed around it, adding to the visual and tourist appeal of the area.

Cheshmeh Gilas is easily reached via the Mashhad–Quchan road and the northwest route out of Mashhad, and because it is so close to the city it is a popular destination for day trips. The best time to visit is spring and especially summer, when the weather is cooler and more pleasant than in Mashhad and the surrounding natural environment is at its greenest. Visitors should follow the principles of responsible nature tourism, avoid polluting the water and the environment, and not damage the natural and historical fabric of the area, so that this valuable heritage is preserved for future generations.
