Sardhar is said to derive its name from the Sardbnri Dhar, a long trap dyke, which is one of the principal watersheds of the centre of Kathiawar. As the town was at the head or beginning of the dhar or dyke it was called Sardhar or head of the dhar or dyke. The dyke consists of columnar basalt and has a length of approximately 50 km (more than 30 miles) at a height of 12–30 m (40–100 feet).[1]
Sardhar is well connected via road being at the crossroads of Highway 25 and Highway 122. The village has all the base amenities such as a bank, a post office, a petrol pump, a police station and a local market.
