Khambhat, also known as Cambay, is a city and the surrounding urban agglomeration in Anand district in the Indian state of Gujarat. It was once an important trading center, but its harbour gradually silted up, and the maritime trade moved to Surat. Khambat lies on an alluvial plain at the north end of the Gulf of Khambhat, noted for the extreme rise and fall of its tides, which can vary as much as thirty feet in the vicinity of Khambat. Khambat is known for its halvasan sweet, sutarfeni, akik stone and kites (patang), and for sources of oil and gas.
