Sika Tanki

Colourful wall on Grgur dived down the anchor line, known for current

Area photo: Nem80 · CC BY-SA 3.0

A wall on the island of Grgur off Rab, past the site called Canyon, that is known for its current and its colour. Boats anchor in 8 to 10 m and divers follow the anchor line down; the outer wall runs to 40 m under sponges and gorgonians, and nudibranchs, conger, octopus, lobster, sea bream, wrasse and scorpionfish are the common sightings. Kron Diving runs it by boat from Kampor on Rab.

The dive

The boat anchors in 8 to 10 m of water and the dive starts by following the anchor line down. That is the sensible way in here, because the site is known for its current: the line gives you a fixed reference from the surface to the reef and the same reference on the way back, so nobody has to find the boat in open water.

The operator describes the site as shaped like a figure 8, usually started from the middle with the wall on your left shoulder. The outer wall drops to 40 m and is covered in coloured sponges and gorgonians; follow it with the rock on one side, checking the current and turning back with enough gas to return along the wall and up the line. Coming back to the middle you pass a small tunnel at 10 to 15 m.

The shallow leg between the site and Grgur is where the small life is. Nudibranchs, conger, octopus, lobster, sea bream, wrasse and scorpionfish are the animals most often met here, and the operator suggests looking into the anemones for spider crabs or, more likely, harlequin shrimp, so keep your pace slow and look into the holes before you head back up the anchor line.

Season follows Kvarner: Peak season is May to September and conditions hold into October; from winter into early spring the bora churns the water and brings current, with the sea at 12–14 °C.

Know before you go

  • Current: the site is known for it. Descend and ascend on the anchor line and turn the dive with gas to spare for the return along the wall.
  • Depth: the outer wall runs to 40 m from an anchor in 8 to 10 m; set a floor before dropping down the face.
