Been to Praia de Roche (sp) Dove in the shallow end of the pool before I'd even left my bags up to the appartment and cracked my head open.
I had what I thought was a Creek in my neck for the rest of the week and drank through it. Came home and still sore so went to the hospital and one of my vertebrae had near come out. Follow up appointment with a top doc and he said its a miracle I was able to walk to the appointment.
It's great for picking up girls apparently. Especially if you like them very young and don't want to meet their parents.
Never been to Cascais Mick, i'm strictly an Algarve guy, if the people are half as nice in Cascais as they are everywhere else you can't go wrong.
