you can come down nh 7 to bangalore and from bangalore-hosur-raykottah-thoppur-mettur-bhavani-coimbatore-palakkad-thrissur-cochin.
this route wil save you a good 25 kms and the roads are pretty good till coimbatore...the coimbatore palakkad section is quite bad due to the rains but you have no other choice..
on the way back you can goto coimbatore-mettupalayam-kothagiri-ooty-mysore through gundalpet-bangalore and then to hyderabad...
the conoor roads are pretty bad and i would suggest you take the kothagiri road which is a few extra kms but the roads are awesome which one would love drivin on |
