Time Out says
Dive from Brulo to Žontulo
In operation since the early 2000s, the Diving Centre Poreč offers both instructions and guided dives to sites around the area, as far as the Limski kanal and Rovinj. Beginners can start with a basic two-hour scuba session, culminating in a first sea dive, while those with slightly more experience can search for starfish and seafish in the shallow waters of Uvala Brulo on the doorstep. More seasoned divers then explore Žontulo, Frižital reef and around Sveti Nikola island. Diving Centre Poreč holds a special permit from the Croatian Ministry of Culture, meaning that it can take the most experienced divers to the wreck of the Coriolanus, a Royal Navy trawler that sank with 40 men on 5th May 1945, two days before the German surrender was signed.
