If you in Delhi cantt area or Dhaulakuan area and wish to travel to Gurgaon, then take DTC or Haryana roadways Low floor Buses. Go to Dhaulakuan bus stop and wait towards the metro station side of stop. In every 5-10 min, a low floor bus (AC bus during morning and evening hours) come. Don't opt for the private buses that start from Sarai kalen khan and go to Gurgaon via Dhaulakuan. They are very unsafe and filthy. Opt the Govt Low floor buses (DTC or haryana roadways). The route to gurgaon always suffer very bad traffic rush, specially near the RR hospital, Subrato park and manekshaw center crossing. Once the bus crosses the Manekshaw center and hits the highway, then its all smooth and rapid ride.
