Prvić Tunnel
On the north side of Prvić, between Krk and Rab, a tunnel about 35 m long cuts straight through a rock, entering at around 12–15 m and exiting at about 9 m. Next to it a wall covered in sponges, white corals and anemones drops to 40 m, with schools of fish, octopus and conger eels. The tunnel itself is a good place to look for nudibranchs, and tuna are sometimes seen offshore.
depth: 9–40 m
