Incomparable natural beauty meets ocean myths and legends. Marine archaeology has verified the existence of old shipwrecks of historical interest dating back to the 4th and 5th centuries or the Byzantine period. Since 2011, there are 14 spots in the marine park where diving is allowed, according to the Greek Official Gazette No. 1741/3.8.2011 - "Approval of re-delimitation of the marine archaeological site of Northern Sporades & Alonissos".
The sea world has so many new experiences to offer! The largest natural marine park of the Mediterranean Sea is found in Alonissos. Its impressive wildlife and amazing landscape give the feeling of intact natural surroundings. It’s no coincidence that Alonissos is the natural habitat of the Mediterranean monk seal (Monachus monachus) and other rare wildlife species forming the precious ecosystem of Northern Sporades.
