Dodabetta is the highest mountain in the Nilgiri Hill at a height of 2623 meters (8652 feet) above mean sea level. The name `Doddabetta` is a compound of two Kannada words, `Dodda` which means big and `betta` means mountain. There is a reserved forest peak around the peak.Dodabetta is four kilometers in the southeast of Udagamandalam which was formerly called Ooty in the Nilgiri district of Tamil Nadu.

The peak can be accessed from the summit with the help of a road. The beautiful Chamundi Peak can be seen from the peak. Hecuba at a height of 2375 meters, Kattadadu at a height of 2418 meters and Kulkudi at a height of 2439 meters are three peaks located in the west of Doddabetta range. It is the highest peak in the Nilgiri plateau and has a unique flattened curve at its pinnacle. Shola vegetation cover the slopes and slightly short rhododendron trees in the middle of the thick coarse grass and the flowering sub-elphine shrubs and herbs are common even near the summit.

An observatory at the top provides a telescope where visitors can enjoy the magnificent panorama of the whole district.
