Sakarun is a spacious sandy beach around 800 metres long that opens on to the open sea of the Adriatic. It is situated on the north-western coast of Dugi Otok, near the settlements of Veli Rat, Verunić, Soline, and the better known Božava. The fine white sand gives a special blue-green colour to the sea. Sakarun is one of the most beautiful and best known beaches of Zadar County. The shore is covered in shingle. The sea is very shallow, even up to 100 metres from the coast. At the swimming limit, approximately 250 metres from the coast, the depth is around 3.5 m. 

On the beach, there are two catering facilities: a cocktail bar and a barbecue stall. In the summer, a small train comes every hour from the hotel compound in Božava. The beach itself is unfortunately exposed to the open sea, which brings rubbish, so that cans, plastic bags, bottles, seaweed and the like are not an infrequent sight.

It is a large bay and popular berthing place and you can nearly always find a place to anchor. The bay is well protected from the winds, except the southerly jugo. When the jugo blows, it is better to moor at the buoys in nearby Pantera.  
From the bay, you can take a 30-minute walk to Verunić and Veli Rat.
