Primošten & Rogoznica

Diving here is run from two harbours. Diving Center Pongo sits at Raduča ul. 11 in Primošten and Deep Blue Diving at Miline 120 in Rogoznica, a minute's walk from the sandy beach. Deep Blue works its own fast boat and names Allans cliff, the Sweet wreck, Mulo, Planka, Plavi tunel and the Jastreb airplane wreck as its sites, all of them on this stretch of coast. Little of that is far: the training beach Deep Blue uses is 100 m from the centre with a sand bottom and 5 m maximum, and Blue Lagoon is a closed bay whose seabed falls gradually, used for discovery dives. The two centres share sites under different spellings — Allans cliff and Alains Cliff, Plavi tunel and Blue tunnel.

The terrain is plateau and wall. Alains Cliff, catalogued as Smokvica Vela Wall too, has a plateau at 3 to 8 m before a drop-off that the catalogue traces to 90 or 96 m, with a canyon of red gorgonian and schools of fish on the part a recreational plan reaches. Orange Cliff is a face of orange gorgonians and lobsters with swim-throughs full of nudibranchs at the end of the dive, and gorgonian fans grow at depth off the Mulo lighthouse while the shallows there hold the fish. Coal wreck runs from a 13 m plateau down to about 27 m, and Fallen Lighthouse has a reef grown over pottery and broken amphorae 2,000 years old at 13 to 18 m.

Current is what varies between sites. Grbavac wall almost never has any, which makes a 45 m wall an easy dive, while Kalebinjak is swum as an anticlockwise lap of the islet with current almost always present, and Cape Planka, 2 km southeast of Rogoznica, is a documented navigation hazard where northern and southern weather systems meet and several ships have been wrecked. The mix suits divers who want walls, small wrecks and course diving from one harbour. Anyone after longer, sheerer walls has the Kornati about 55 km northwest, on a national-park ticket.
