One day we decided that we wanted to have a romantic picnic along the western coast of Portugal, so since we were staying in a B&B in the Sesimbra area, we got in the car and headed west and drove from south to north along the coast, looking for a place. We finally found Casa do Infantada (not on the VT map), had a coffee at a local shop and then drove toward the sea. We were not disappointed, a beautiful sunset although not as spectacular as some we have seen still a joy.
Near Espichel Cape, inside the Arrabida Natural Park there is a very small bay with a rocky beach just acessible by jeep, amazing sunset and the place to be if you want a beach just for yourself, even in the summer.
In the summer just gather some freinds and take "amunitions" to spend one night experience camping in this wonderful bay, take a guitar, music, beer and thats it, you will not wont to live in the next day. Its a hard track to get there down the cape but locals will tell u how.
