Clear blue waters, organized or non-organized beaches and beautiful places to explore, relax or... take summer photos. Agios Demetrius, Kokkinokastro, Leftos Yalos, Megalos Mourtias, Milia and Chrissi Milia are some of Alonissos' most typical organized beaches.

Along the south-eastern coast of the island, there is a variety of beaches for all tastes! If you are looking for sceneries of golden sandy and colourful pebbly beaches or rigid yellowish rocks and reddish cliffs, this is the best place for you. Most of the beaches here are hidden or well-protected in bays and surrounded by pine or olive trees.

The north-western coast of the island is rocky and often inaccessible by land because of craggy terrain and steep rocks sinking sharply under the sea. The various small beaches in the northern part of the coast are only accessible by boat. For beaches accessible on foot or by car, visit the southern part of the coast. Nice small beaches are also found along the gulf of Megali Ammos.

The Historical and Folklore Museum of Alonissos is a source of historical and cultural information about an island with fascinating history and traditions. It is housed within the premises of an impressive stone building in Patitiri village. The Historical and Folklore Museum of Alonissos is a private institution, established in 2001 on the initiative of Konstantinos and Angela Mavrikis.

On the ground floor, there is a wide collection of ancient Greek exhibits including weapons and various utensils retrieved from old warships and pirate ships. This interesting collection revives legendary pirate figures - active from the 16th to the 18th century - that never fail to stir visitors' imagination. There is also an underground space especially designed for traditional objects and other utensils of everyday life. Exhibits such as old barber razor blades, traditional oil presses and outfits offer a short yet exciting journey back to the traditional life of the island.

Patitiri village is the picturesque central port and the capital of the island. "Patitiri" in Greek means "wine-press" and therefore, the name of this area dates back to the time when viniculture was the main source of income for local population. In the port of Patitiri, there are several cafés and local taverns to choose from and enjoy the ambience of the port, watching the fishing boats and yachts lying at anchor. Walking to the end of the port, there is a small beach with crystal blue waters surrounded by yellowish rough cliffs and pine trees. By nightfall, all these cliffs are beautifully illuminated. Looking towards the end of the bay, you can also see two neighbouring islands called Dio Aderfia (Two Brothers).

The National Marine Park of Alonissos and Northern Sporades was the first marine park established in Greece and is currently the largest marine protected area in Europe. The National Marine Park of Alonissos and Northern Sporades is member of the MedPAN (Network of Marine Protected Areas in the Mediterranean). Founded in 2003 and funded within the framework of the "Environment and Sustainable Development" operational program, its management body is responsible for the preparation and implementation of the management plan relative to the Marine Park.

The Board of Directors of this management body consists of 10 members, who represent national, regional and local authorities, local professional associations and non-governmental environmental organizations. In 2010, Professor Stefanos Paraskevopoulos, University of Thessaly, Department of Special Education, was appointed Chairman of the Board.

The efforts to protect this area began in the early 1970s. In 1986, the Prefecture of Magnesia signed the first resolution aiming to the protection of the Mediterranean monk seal (Monachus monachus) and its natural habitat. These efforts were followed by a series of ministerial decisions on the protection of the local nature reserve. In 1992, the area was finally declared a "National Marine Park". In 2007, properly trained scientific and technical staff was hired by the management body of the National Marine Park, registered in Alonissos, for the implementation of protection and research programs, as well as public awareness and sensitization campaigns. A five-year management plan is also in course of preparation.
