It is around 150 to 160 kms from Delhi and can be reached in 3 hours time by car.
The condition of the road is average to good.
For reaching Narnaul, you can take the Delhi-Jaipur National Highway NH48 (formerly called NH8) till Behror (which comes immediately after Neemrana) and then leave the NH to take the smaller road towards right at the Behror intersection point.
You have to be careful to stay left and come right under the flyover and then take the right just under the flyover to reach the road that goes to Narnaul.
Even after one leaves the NH, the road condition is quite good.
Though there are many places to see in Narnaul, on a recent family trip, I managed to just see two of them - Dhosi Hill and Jal Mahal.
Dhosi Hill
The first place I visited was the Dhosi Hill.
In many places on the Internet Dhosi Hill is incorrectly called as Dhonsi Hill.
It is actually Dhosi (or maybe Dhausi) and not Dhonsi.
There is no "n" in Dhosi or Dhausi Hill.
This hill has couple of temples and an extinct volcano site.
The trek to the the Hanuman template in the middle of the hill and then from there to the top of the hill is quite enjoyable as there is a proper track which is in an excellent condition.
Here are some of the photographs of the Dhosi Hill in Narnaul.
Jal Mahal
The second place I visited was the Jal Mahal in Narnaul.
This is the place Emperor Akbar used to frequent while passing through the Narnaul area.
When I visited, there was no water at all.
There was no "Jal" or water in the Jal Mahal.
Despite that, the whole place looked splendid even without the water.
Here are some of the photographs of the Jal Mahal in Narnaul.
