Island-hopping walls and wrecks in the clear Adriatic

Croatia is Mediterranean diving with a very specific flavor: clear Adriatic water, limestone walls, caverns, and a dense catalog of wrecks. Choose the north (Istria and Kvarner from Pula to Krk) for wreck history and quick logistics, or head south into Dalmatia for island chains, deeper drop-offs, and park-style seascapes. Expect visibility often 15 m to 30 m when you go offshore, and plan exposure protection around a sea that ranges from winter lows near 10°C to summer highs around 23°C to 25°C. The big constraint is regulation: some sites require park permissions, cultural-heritage wrecks need special access, and independent diving may require an individual authorisation.
Punta Silo (Krk)
A popular Kvarner site that works for both training and relaxed fun dives.
100 Steps - Vrbnik (Krk)
A classic shoreentry vibe on Krk and a great option when you want flexibility.
Banjole (Istria)
Convenient Istria diving for warmups, refreshers, and macro hunting.
Canyon
A dramatic terrainstyle dive that hints at the Dalmatian wall experience.
Baron Gautsch
A headline Adriatic wreck near Istria and one of the classic history dives.
Sveti Marak (Krk)
Shallowtodeeper terrain that suits mixed groups and photo practice.
Operator Checklist
Pick your coast first, then fill in islands. For wreck focus and short transfers, base in Istria or Kvarner. For clearer offshore diving and island variety, base around Zadar, Sibenik, or Split and add day boats. If you want national-park diving (Kornati, Brijuni, Telascica), book a dive center that can organize park access and follow the local rules on zones, depths, and timing. If you plan to dive without a guide, verify whether you need an individual authorisation and how to mark your dive area with a surface buoy and flag.
