KRS Road is an important road on the tourism map of Mysore. This is the road that takes you from Mysore city to the popular attractions like Brindavan Gardens, Ranganthittu Bird Sanctuary or even to the off beaten destinations like Balmuri and Yedamuri Falls . Of course you can take the KRS road from Mysore city to reach Srirangapatna too.
KRS Road starts on JLB Road from near Mysore Railway Station. Its about 18km from Mysore city to KRS ( Brindavan Gardens). From near the railway station KRS Road takes you to the Railway Museum, CFTRI , All India Radio, Cheluvamba Park, Vontikoppal, Metagalli and then crosses the Ring Road near the GRS Fantasy Park. If you turn right in to the ring road, you will finally hit the highway to Bangalore.
Otherwise after this junction the KRS Road crosses the railway line near the Golden Landmark Resort. Further it passes through the industrial suburbs of Mysore and the scenery suddenly turns rural.
Many kilometers later the road hits a Y fork. Turn left for places like KRS, Brindavan Gardens, Balmuri and Yedamuri or even Yelwal which is on the Hunsur Road.

Or take the right fork of the Y to  Ranganthittu Bird Sanctuary, Srirangapatna , Bangalore etc.
Weather you turn left on right, the road now runs almost parallel to the River Cauvery, though you may not see the river soon. But the journey is through the lush paddy fields which is the delta irrigated by Cauvery.
The other ways to access KRS road apart from Mysore City are from Srirangapatna and also from Yelwal on the Hunsur Road.

Though not specific to KRS Road, beware of those smoke blenching mofussil buses and the screeching maxi-cabs. It seems it is on the KRS road that everyone tries to catchup on that lost time.
You can also take a city bus from Mysore City Bus Stand to KRS. Oh yes, they do operate the AC city buses (Volvo) too to KRS.
