North Coast -- Watergate Bay, Harlyn Bay, Crantock Beach, Fistral Beach, Perranporth. All long wide beaches where it is possible to rent body boarding or surfing equipment and to take lessons. Also nice to walk along, with good cafes to grab some tea and cake.
South
Coast -- Lantic Bay,
Lansallos
Beach, Readymoney
Cove Beach, Fowey
Estuary, and Polperro,
Looe and Whitsand Bay. Smaller beaches with less
infrastructure, but beautiful especially if as part of a walk. The
coast path that runs along the South Coast encompasses these
beaches. It can be nice to do a walk here and stop off in Polruan
or Polpero for lunch.
