Carabassi Beach
The clean and sandy beach, which is very safe to children - flat, no rocks, no seaweed etc. -is 8 km long, and is situated at the foot of the hill, on which Gran Vista is build. You can easily walk DOWN the hill directly to the beach - however, it will require a bit more "patience" to walk back up again ! But - it can be done.
Most people prefer to take the car and just let it roll the pair of kilometers in question down the road - so that it`s there for the return trip! Or take the small local tram/train.
