The last bay on SW side of island Mali Lošinj is called Plijeski. It’s relatively open so I don’t recommend staying the night but it’s very nice to take a swim because of its turquoise water and sandy beach.
If you want to drop anchor and stay the night I recommend coves Krivica, Balvanida or island Ilovik a little further to the south.
You may also get lucky and get a bite to eat from the tourist boats which come there every day and prepare barbecue – usually fresh fish and squid.
The most Famous of these boats is a small ship called Mate or Mateo.
