Mamula Island sits at the entrance to the Bay of Kotor on the Adriatic Sea and is a wreck-focused diving destination for intermediate to advanced divers. All sites are boat-access only. The site list includes the Tihani, a steamship built in nineteen-oh-eight that sank in nineteen seventeen and now rests at depths between thirty-five and forty-two metres on a sandy bottom, the patrol boat wreck Patrolac serving as an artificial reef, PBR five-twelve, and a former military submarine tunnel. Rt Dobrec adds a wall-and-reef profile with ancient ceramics embedded at the site. Water stays around fifteen degrees from winter through mid-spring, warming to the low twenties by autumn. Species recorded here include grouper, conger eel, giant barrel sponge, rugose spider crab, and Mediterranean cardinalfish.

Temperatures remain steady at around fifteen degrees for much of the year before rising gradually from late spring, reaching the low twenties by September and October. The cooler, stable conditions suit the deeper wreck dives, though divers should plan thermal protection accordingly. Advanced divers visiting the Tihani wreck will encounter the lower end of the annual temperature range at depth.
