Guincho Beach

Guincho Beach - Cliffs outside Cascais give way to a great bank of sand ringed by hills.

It is one of the most beautiful beaches around Lisbon (also with one of the best sunsets), but can be windy and the waves are powerful, which doesn't make it the best beach for swimming. But many see it as the best place for windsurfing in Europe (it has hosted world championships), and when the wind dies down in the early or late hours, it is also good for surfing.
