Submarine tunnels in Kotor Bay were built during the 1970s by the Yugoslav Navy. They were designed to host submarines and small ships. The tunnels are now abandoned. They can be reached by car from the village Rose, or easily by boat.
A headlamp is needed to find the cache. Gloves are recommended.
Your task is to find two numbers ABC and XYZ inside the two tunnels. See the photos.
First tunnel
(Posted coordinates, N 42° 25.664' E 18° 35.405')
Second tunnel
(Waypoint 01, N 42° 25.818' E 18° 34.875')
Final cache is at coordinates N 42° 25.ABC E 18° 34.XYZ
FINAL:
Enter the bunker at these coordinates. Inside there are two ladders going up, climb the one at the far end of the bunker. The cache is at the top of the ladder. Look for a small black X on the wall. The cache is within 20 cm, under stones.
