Myself and my wife planned to drive from Hyderabad to Delhi when I was relocating from there. The journey has to be really planned one with hotel/stay reservations, basic medical kit, some ready food stuff etc.
The road stretch is all okay except a big patch (70 km) in between Jhansi and Gwalior. We planned to split to three days as I was alone gonna drive.
The first day was from Hyderabad to Nagpur - and the road was just amazing. The car was just flowing on the highway. It was an amazing track, bypassing all the small towns and the cities. The best place you get to eat is Adilabad, the last district of AP and then MH starting. As i mentioned, keep some fruits, chips, buns, juice packs with you right from the beginning as you get very few shops on the highway.
We stayed at Circuit House in Nagpur which was poorly managed and kept, a night to spent was difficult but we did not waste our time hunting for some other location as the next day was really long.
Day 2: Started from Nagpur at 06:00 Hrs. The morning drive through Pench National Park was just too good. The road has some patches and you feel your driving in some remote locations but no big hassles, as its very small stretch and gets over in couple of hours. The Pench crossing covers almost 50 Km and you don't get any tea stalls, restaurants, small cars etc on the way. So whenever you start the day, have good breakfast and keep some stuff to munch in between if you don't get good food on the way. After Pench, you enter in Chattisgarh, and trust me guys the best roads were in Chattisgarh. The highway passing across spreaded fields and small tiny houses. We got the first decent place to eat 1200 Hrs, so thought to have a brunch as the journey was nice but with less of resources. A small village on top of hills in CH called KHAPA was amazing to take 10 min break and stretch your body.
The highway was the highway until we entered Jhansi (MP). We reached Jhansi before 1600 Hrs and covered 600+ km. The blunder was after Jhansi.
No roads at all, its just mud with big Holes and people drive left right centre everywhere. It took 4 and half hours to cover 100 km from Jhansi to Gwalior without any break. I'm sure you can imagine the road situation.
Day 3: Gwalior to Delhi was fun, just 5 hours quick drive and the best in Yamuna Expressway. After reaching Delhi, the only regret of the entire journey was Jhansi to Gwalior.
Keep enough cash handy as you don't get ATMs on highway. Keep a tab on your fuel tank, don't let it go below 1/4th any time. Carry some small tit-bits, fruits, juices, cookies with you. Be very careful of heavy duty vehicles, you encounter most on the way. Try to drive only during the day light, there are no cities / towns you passes through on the way. So if you get stuck somewhere, you may have to spend a night there itself. Carry fully equipped first aid kit.
