Krk reef with a tunnel, wall, and gorgonian slope.
Tenki Reef is a boat-access Krk reef with a shallow top, a passable tunnel, a valley, and a wall that opens into deeper structure. The site rewards a slow, controlled dive because the reef face carries gorgonians and sponges, while conger eels, groupers, and scorpionfish are tucked into the tunnel and the broken rock. It is a better fit for confident open-water divers than for a casual sightseeing stop, and the variety makes it one of the most distinctive dives on the island.

Typical Conditions
Shallow tunnel, wall, and valley with a mix of shallow and deeper structure; the site rewards a slow look rather than a fast pass.
Site conditions, restrictions, and access requirements.
Site Conditions
Safety Notes
Keep a tight buoyancy profile through the tunnel, respect the deeper wall, and plan for visibility that can change from dive to dive.
Access Restrictions
Boat access from the Krk and Vrbnik area is the normal approach, so it is best treated as a guided island dive.
Legal Notes
Use the local operator briefing and follow any Krk-area site rules that apply to the reef and tunnel.
Community notes to help plan your visit.
Scuba Diving
Broad depth range (3–60 m) with shallow and deeper features, including a wall and a swim-through tunnel.
Freediving
Only the shallow top suits freediving; the tunnel and deeper wall are better left to scuba.
Snorkeling
Snorkeling is secondary here because the most interesting features sit below the surface and through the tunnel.
