Williamstown Beach is stunning! The beach is clean and it's the perfect spot to sit and relax with fish and chips of a refreshing ice-cream! There's also a path which follows the coast right around if you fancy a walk, jog or bike ride (there are O-Bikes around the place, just download the app to find them...although to be honest there seemed to be quite a few ghost bikes around the place and myself and my partner couldn't find one that easily). I would recommend catching the train as it can be pretty packed on hot days and parking can be limited. Today was really hot and there were still heaps of people about at 7pm. But the beach isn't very far from the station at all and it's a flat walk to the seaside.
