Slovenia lies at the heart of Europe, where the Alps and the Mediterranean meet the Pannonian plains and the mysterious Karst. In Slovenia, you can experience amazing contrasts in the same day: a morning swim in the Adriatic, followed two hours later by skiing below Alpine peaks. Slovenia joined the EU in 2004.

Getting there

  • Out of Piran, there is an Italian military transport ship from the WW2. It lies between Piran and Strunjan about 2,9 km off the Madonna peninsula in Piran. Little is known about the wreck except that it belonged to Italian navy and that it was probably sunk in the spring of 1945 by aircraft. It has a steel hull and a length of 47 metres with 3 propellers and 2 rudders. It is lying upside-down on a sandy bottom at a depth of 24 metres.
  • The Fiesa Reef is the most visited reef in Slovenia, due to easy approach by road. It is popular for Slovenian dive schools - normally with good visibility and the depth on the reef doesn’t exceed 9 metres. Popular for night dives. The marine life is varied with squid, octopus, seahorse and lobsters.
  • The Punta Reef is probably the best that the Slovenian Adriatic Sea has to offer. There are 2 dives that can be done, the northern and southern sides, which can be convenient depending on the weather, as one side can be calm whereas the other maybe be rough. The maximum depth on the southern side is 12 metres. On the northern side, the maximumdepth is 22 metres.
