Of Gingee's three citadels, the easiest to reach, Krishnagiri, rises north of the road. To the south are the highest of the three, Rajagiri, and the most distant and least interesting, Chakklidurg. It’s a good hike to the top of Krishnagiri and even more so to the top of Rajagiri (more than 150m above the plain) and you need half a day to cover both hills. Most visitors climb Rajagiri, which makes Krishnagiri much quieter. Start early and bring water.
