ದೇವರಾಯನ ದುರ್ಗ is a hill station near Tumkur in the state of Karnataka in India. The rocky hills are surrounded by forest and the hilltops are dotted with several temples including the Yoganarasimha and the Bhoganarasimha temples and an altitude of 3940 feet. It is also famous for Namada Chilume, a natural spring considered sacred and is also considered the origin of the Jayamangali river. Another famous temple in the area is the Mahalakshmi Temple at Goravanahalli.
Namada Chilume is a natural spring situated by Devarayanadurga, near Tumkur in the state of Karnataka in India. The spring issues from the surface of the rock. It is believed that Lord Shri Rama, along with Sitha and Laxman, stayed here during their Vanavas. Lord Shri Rama searched for water to apply nāma/tilak on his forehead. When he couldn't find any water, he shot an arrow aiming at the rock. The arrow penetrated the rock, made a hole, and the water came out. Henceforth this place was called Namada Chilume, meaning "Spring of Tilak". As shown in the picture, the water comes out from a small hole throughout the year and never dries up.
It is 65 km from Bangalore, India, by road on Tumkur road.
There are two routes to this place.
From Banglore, go till Dobbespet. Go under the flyover and take a right (Note: The left here leads to Shivagange betta and right leads to Devarayandurga). On this route you get Devarayanadurga first, and then as you go towards Kyatsandra, you get another Hanuman and Shankara temple, a little further is Namada Chilume and then Siddaganga mutt (different from Siddagange betta) and a kilometer from there is Kyatsandra where you hit Banglore Tumkur road.
The other route from banglore is from Kyatsandra. About 1 km after crossing second toll gate on Tumkur road take right at Kyatsandra. After crossing railway level cross you reach Siddaganga Mutt then Namada Chilume then Hanuman Temple and finally Devarayanadurga. The roads on this side are much better and this route is shorter.
