From Shimla, take the NH 5 towards Narkanda, but turn off right at Theog towards Kotkhai and Rohru on the SH 10. After 5 kilometres take the U-turn to the right - a new road. Keep going down to the bottom of the valley, cross the bridge into Chailla. One kilometre after Gumma take a left down into the valley below. There's a yellow and green sign for 'Roots Country School'. You can see the Technical College and a HP Cricket Ground below you to the left. Cross two small bridges and 500 metres later take a right, single track road up the mountain, signposted Chadiana 6 kms and Reoghati. At the first bifurcation take the hairpin left by the rain shelter. Do not take the right to Purag. At the second bifurcation take the hairpin right. Do not take the left turn to Keeth. One kilometre after this second bifurcation you are in the small village of Rukhla. We are the second double garage on the right as you leave the village and head for the forest. There is a black Force Gurkha jeep. The farm is called Smitra Orchards and is below the road to the right with red roofs. If you stop and ask a local for confirmation, Michael is the only non-Indian in the area and his father-in-law is Jagjit Chauhan is a well-known figure, aka Kaka.
An alternative route avoiding crowded Shimla and Solan is to turn off the NH5 at Kumarhatti and follow the signs to Shoolini University. Then take the SH 6 to Ochghat, Sainj and Chailla where you join the SH 10 to Gumma. The Solan to Chailla stretch (the Rajgarh Road) is very narrow, mostly recently metalled (95%), with little traffic, scenic, but a little scary if you're not used to mountain roads. It's shorter but slow so it takes around the same time as going via Shimla (depending on Shimla traffic, which can be bumper to bumper).
