Much of its relaxed vibe comes from the water that permeates the city. A natural harbour-the result of Malabar mud banks- separates the towns of Kochi and Ernakulam, which together make up the conurbation that was known in the British era as Cochin. Consequently, getting around town often requires the use of a bridge or ferry, which, while it doesn't make for the quickest journeys, can be very pleasant for the leisure traveller. The Water surroundings also have the effect of making the city feel very clean by Indian standards.
