Pictures are on the way.
Shall try to provide some information I have.
At a junction in Dharampur, we thought of checking the route with some local persons. We asked one person and he directed us to take a right turn. (Felt that this lorry cleaner/driver who shown us the way was laughing at us sheepishly once we took a right turn).
After a few kilometers, found out that there are signboards showing Vapi and distance to Vapi is coming down. Re checked with another person on a bike and took a U turn. We came 9 km in the wrong direction. Went back another 9 km and took the correct turn (now its right turn) at that junction.
It was good smooth road from Dharampur. After some distance, only issue was isolated potholes appearing suddenly in an otherwise good road.
Geography changes, once we reach near Vansda.
There are some places of interest in this area.
Waghai Botanical gardens, Vansda National Park, Gira water falls etc.
Botanical gardens and National park are on either side of the road. Waghai Botanical gardens comes first to our left and then Vansda National park to our right.
Gira water falls is some distance away from the main road.
We did not go to Gira. Just posting a file picture here.
