Fog lifts off the Adriatic as the glass-bottom boat cuts a slow arc out of Bunarina, sunlight slipping under the hull to reveal the seafloor like a map. Salt-scented air and the soft clack of oars set the tempo; beneath, pen shells and schools of small fish drift through seagrass beds while cliffs of Verudela rise on the horizon.

Fog lifts off the Adriatic as the glass-bottom boat cuts a slow arc out of Bunarina, sunlight slipping under the hull to reveal the seafloor like a map. Salt-scented air and the soft clack of oars set the tempo; beneath, pen shells and schools of small fish drift through seagrass beds while cliffs of Verudela rise on the horizon.
This short morning cruise traces Pula’s coastal geology — limestone coves, submerged canyons and the low karst islands of Fratarski, Frašker and Fraškerić — that have shaped local fishing and boat-building traditions since Roman times. The archipelago’s coves hold starfish, sea urchins and pen shells in clear, cool water that invites a quick dip between 10:00 and 11:30 a.m., when visibility is often at its peak.
Expect a gentle, family-friendly outing: observation through a glass hull, stops near caves and a chance to enter the water for a supervised swim. The itinerary moves from Pješčana uvala past Fratarski’s canyon and between Frašker islands, finishing with Verudela’s cave views. Guides point out marine life and local place names — practical context that brings the shoreline to life.
Practical tips: arrive with swimwear and reef-safe sunscreen, bring a towel and water, and plan for a 90-minute window in the morning when winds are usually lighter. The tour is easy on fitness but requires basic water comfort for swimmers. Respect marine life — view, don’t harvest — and enjoy a compact coastal portrait of Pula that balances quiet observation with the possibility of a bracing Adriatic plunge.
