Sika Tanki is a boat wall dive on Grgur with strong current.
Best handled as a guided Rab-area boat dive because the site is current-sensitive and entered on the anchor line.
Sika Tanki is a boat-only wall dive on Grgur, reached after Canyon, and known for its color and strong current. Divers anchor in shallow water and drop down the line before following the wall and ledges. It suits experienced scuba teams that can stay close, time the turn carefully, and keep buoyancy disciplined along the wall.

Community notes to help plan your visit.
Scuba Diving
Best run as a guided wall dive with an anchor-line drop, a steady wall pass, and an early turnaround if the current starts to push.
Freediving
Not a practical freedive target; the boat entry and current make it a better scuba-only site.
Snorkeling
Snorkeling is not the main use case here; the wall and best life sit below the boat.
