Boca do Inferno
One can only guess from the Portuguese name of this spot that something hectic is happening there. Its actually a very rugged piece of coastline up the coast from Cascais where the waves smash into the cliffs. The walk there took us past the small boat harbour, the citadel and some very beautiful Portuguese architectured buildings. The sea was relatively calm so there wasn't a massive spectacle when we got there, but it was still a wonderful sight.
