The morning light flakes off the Adriatic as the speedboat cuts a bright line through the Zadar channel. Salt stings a little, gulls wheel overhead, and the old city fades behind you while the skipper plots a short hop to sandy bays and tiny island villages.
This four-hour island hop hits Kostanj beach for swimming, Ošljak — the Adriatic’s smallest permanently inhabited isle (0.39 km², ~29 residents) with a 6th-century Church of St. Mary and windmill ruins — and Preko on Ugljan, an evergreen island shaped by millennia of olive cultivation. Geology here is limestone and karst; coves form where the rock meets slow waves, producing clear water and sandy patches ideal for snorkeling. Culturally, these islands retain working fishing ports and centuries-old olive terraces; you’ll see small harbors and houses built close to the shore, reflecting a life tied to the sea.
Practically, expect short boat transfers between stops (a few nautical miles at most), roughly 60 minutes ashore at Kostanj and Ugljan and about 45 minutes on Ošljak per the itinerary. Snorkeling equipment is provided; bring reef shoes for rocky entries and a dry bag for valuables. The trip is family-friendly but not recommended for pregnant travelers or those with serious back/heart issues. Carry local currency for small purchases in Preko, time your visit for calmer seas (mornings are usually gentler), and leave seagrass beds undisturbed when swimming.
This is a compact, high-impact seaside day: quick hops, clear water, small-island history, and a skipper’s local knowledge that makes short time ashore feel like full discoveries.
