I am going to a resort in Coonoor for this coming long weekend (2nd - 5th Oct) , so without further ado
here is my plan : Plan 1 : Bangalore > Hosur > Krishnagiri > Dharamaphuri > Salem > Erode > Avinasi > Mettupalayam > Coonoor
Longer but most of router via NH so can reach faster . Plan 2: Bangalore > Kanakapura > Malavalli > Mysore > Najangod > Gundlupet > Bandipur> Masinagudi > Ooty > Coonoor
Well Known Route from Mysore to Ooty Plan 3: Bangalore > Kanakapura > Malavalli > Kollegal> Chamarajnagar> Banari > Bhavanisagar > Mettupalayam > Coonoor
2nd Shortest Distance but unsure about the road conditions
Any suggestions are welcome.
