Prvić Tunnel

  • Max depth12 m
  • CertificationOpen water / no overhead

The dive

A swim-through tunnel the centre calls very easy. On the far side a fine rock face starts, with a good chance of big fish (tuna); ~40 m away, opposite the rock, is another cave (Pillar-Cave).

Prvić has been a protected botanical-zoological reserve since 1972, where griffon vultures breed: don't go ashore or disturb the birds. Ask the centre what currently applies to diving and boating around the island.
