Silo is situated on the south side of Prvic island. The pinnacle starts at around 12m depth. The dive starts following the anchor to reach the top of the pinnacle. On this dive site might be some strong current sometimes. The southern side of the pinnacle has a drop off where the bottom can reach 40m+ and the wall is covered with colorful gorgonians. The northern side, between the pinnacle and Prvic Island has a nice channel, where the bottom is around 30-40m deep.

Tunnel is situated on the north side of Prvic Island. At the northern most tip of the island of Prvic, there is a rock in the water through which leads a tunnel roughly 35 metre long. After the descent, you arrive at the entrance to the tunnel at a depth of around 12 metres. With a diameter of around 3 metres, the tunnel is very easy to dive. You barely reach the other side when one of the most beautiful rock faces in the whole area immediately begins. Anyone who still has enough air in the tank after the dive through the tunnel and the rock face should not miss the Pillar-Cave, which is located only about 40 meters away, opposite the rock.
