From Mysore City exit to the Mananthavady Road (HD Kote Road / SH33).
From Mysore railway station take the JLB Road. At Srinivasa circle turn right in to the Mananthavady Road.
Also you may take the Outer Ring Road that goes around the city to get to the Mananthavady Road.
After about an hour's drive from the city, you'll reach a busy town square called Handpost. You'll see a fuel station on your left, just before the junction. Cross the junction and keep straight.
Under 3km from Handpost, the main road makes a right bend at a junction. If you drive fast, it's likely to miss this junction.
Leave the main road at the bend and take the left road to Kabini Dam.
In about 10km you'll cross the Dam (appear on your right). Keep drive on the main road for another 15km, you'll see a right diversion for the Orange County. It's another 4km drive from this diversion to Orange County Kabini on the shores of the Kabini backwaters.
Also keep in mind the Mysore to Kabini route is quite rural, with no drive-in restaurants or other travelers' facilities. You may like to see the other Kabini resorts options too... Also Cab Rental in Mysore for typical rental rates, if you are planing to hire a cab.
Happy driving. Have a great stay at Orange County Kabini!
