Hayle
Hayle is a town, civil parish and freight port in west Cornwall, United Kingdom. It is located at the mouth of the Hayle River (which discharges right into St Ives Bay) as well as is about 7 miles (11 kilometres) northeast of Penzance. Hayle parish was produced in 1888 from part of the now defunct Phillack parish, with which it was later on integrated in 1935, and incorporated part of St Erth in 1937. The modern parish shares borders with St Ives to the west, St Erth to the south, Gwinear and Gwithian in the east, and also is bounded to the north by the Celtic Sea. Hayle's placement by the sea as well as its 3 miles of gold sandy beaches permitted it to create as a vacation destination. Undoubtedly, Hayle still has much vacation accommodation. The sand dunes or Towans are the favoured place for a variety of vacation towns as well as campers as well as camping sites. The Gwithian coastline near Godrevy is picturesque as well as a popular area for water-related sports including browsing, windsurfing and also body-boarding.
