Peristera Shipwreck: A significant historical site described as Greece's first underwater museum, featuring an ancient wreck with approximately 4,000 amphorae.
Blue Cave: An advanced dive site located at a maximum depth of 30 metres. It features an impressive vertical wall and a cave entrance that creates unique light effects through the turquoise water.
Deep Cave – North: This site reaches depths of 35 metres and is located at the northernmost point of permitted recreational diving in the Marine Park. It features a large, spacious cave with a sandy bottom and vibrant ceiling flora.
Two Brothers’ Reef: An underwater canyon that rises from the pelagic depths to a maximum depth of 25 metres. This site requires good buoyancy control to navigate the monumental reef and steep cliffs.
And some of the dive sites the centre runs.
The marine environment around Alonissos is characterised by rich biodiversity, particularly along the vertical walls and reef structures. Divers will encounter diverse gorgonian colonies and a variety of Mediterranean reef life.
On the deeper walls and near the cave systems, the landscape is defined by complex structures of gorgonians and various sponges that provide habitat for a wide range of species.
Macro life and smaller inhabitants are found throughout the rocky outcrops and sandy floors of the Marine Park, though specific seasonal species lists are currently being updated.
Diving in the Alonissos area is influenced by the geography of the Northern Sporades. Divers should be prepared for varying conditions depending on whether they are diving near the reef flats or on the deeper outer walls.
Buoyancy control is a noted requirement for several of the more technical sites, such as the deep caves and the canyon at Two Brothers' Reef, where maintaining depth is essential to protect the delicate reef structures.
