Western half of the Mljet Island is a national park since 1960. The park is very popular among hikers, bikers and other natural lover visitors. The big bay at the northern end of the island is named as Pomena Bay. This bay comprises several small uninhabited islets. Islet of Pomestak is one of these lovely uninhabited islets.
It is advised to stay on anchor in one of the coves of the islet. If you don’t feel comfortable you can try to use dockage at the pier of hotel Pomena just at the S of Islet of Pomestak.
