The short answer

Dholera is in Ahmedabad district, Gujarat, south-west of Ahmedabad and across the wider Gulf of Khambhat region from Bhavnagar. The modern development area is associated with the Dholera Special Investment Region, which covers a large multi-village planning envelope.

The four places people often mix up

PlaceRole in the regional story
DholeraThe settlement and wider regional development story.
Dholera SIRThe notified special investment and planning framework.
AhmedabadA major metropolitan anchor and the northern transport connection.
BhavnagarA regional urban and logistics reference point across the Gulf.
LothalA distinct archaeological heritage site, not a part of the Dholera SIR.

Why geography matters

Dholera’s coastal position shapes its soil, water, drainage, flood risk, environmental regulation and transport logic. It also explains why a development claim should always be checked against the exact location and boundary being discussed.

Reading a map carefully: a corridor, zone or planning boundary does not by itself prove that a specific private parcel is approved, serviced or available.

Next, remove the category confusion

Once the regional position is clear, the next useful distinction is between Dholera town, the Special Investment Region and the planned industrial city.
