Vypīn

Vypin forms a barrier island which lies between the Arabian Sea in the west and the Kerala backwaters (Cochin backwaters) formed by the various distributaries of Periyar river, in the east. The northernmost end of the island lies on the estuary of the Periyar river in Muziris (Kodungallur), and the southernmost end in the mouth of the Cochin backwaters in Kalamukku near Fort Vypin.

The island is about 27 kilometres (17 mi) long and is connected to mainland Kochi by a series of bridges known as the Goshree bridges, which start at Kalamukku in Vypin, touch other two islands and then finish at Marine Drive covering a total distance of around three km (1.9 mi). Vypin is 58th most densely populated islands in the world. Njarakkal is one of the most densely populated locations within Vypin.
