Actually we are talking about two beaches very different with each other.
The smaller one is sheltered and very cosmopolitan with sun beds and umbrellas, ideal for families. There is a a beautiful picturesque tavern by the seaside and another one on the upper side with a view to Drakonissi and the endless Aegean where you can enjoy your meal.
The larger one is more isolated and exposed to north winds, ideal for surf and chill out. There is a surfing school if you want to catch some waves, handmade “mushroom” umbrellas and a small bar with snacks and cocktails. During the last few years it has become very known in the surf community so you may experience some very good surfing here.
