Pernastica is a big sandy beach on the northwest of Silba. A part of the bay is shallow (particularly its left side). On the shore there are rocks on the sides of the bay, pebble and sand on its end, often covered with seaweeds, the quantity of which varies from one year to another (on the shore and in the sea). On the right side of the bay there are a few indented small pebble coves. A good 4 km long path leads to the village. Islands Ilovik and Lošinj can be seen from Pernastica.
