Alonnisos is a beautiful, green island situated in the northwest of the Aegean Sea, about 40 kilometers from Pelion on the Greek mainland. It belongs to the Northern Sporadic group of islands, which from a geological standpoint are contiguous with the mainland, despite the intervening submerged area. Alonnisos is a roughly oblong island, about 20 km long and between 3 km and 4 km wide. The island has a magnificent and varied natural history which has made a deep impression on generations of visitors.
Even as the boat approaches the island, your first impressions are of a landscape rich in contrasts. The western promontory rises precipitously from the sea in rugged cliff formations to a height of 300 meters but soon rolling, green hills emerge from behind the promontory, and a small village appears at their peak. This village, Palia Alonnisos (Old Alonnisos), is the former main settlement of the island.
After another 15 minutes travel along the beautiful pine-clad southeast coast you arrive at the main harbor of the island, Patitiri. The harbor is situated in a small bay with clear turquoise waters, surrounded by steep, ochre-yellow cliffs. The area behind the harbor is densely developed and the built-up area continues into the next bay, Rousoum, and on into the neighboring fishing village of Votsi.
Apart from these settlements (Palia Alonnisos, Patitiri and Votsi) there are two more villages, both further up the southeast coast. The first is Steni Vala (by road, 10 km from Patitiri), a charming little fishing village and home port for many sailors, as it is the last place to take on provisions before visiting the many uninhabited islands in the area. A little further up the coast is the last small built-up area Kalamakia, which consists of a few houses and a small harbour.
Alonnisos is studded with beaches where you can swim in the crystal clear waters. Each of the beaches is more picturesque than the last, and they are all very different in character.
The colorful landscape, the dramatic cliffs and the wide variety of vegetation on the island make it a magnet for nature-lovers; just to take in the fantastic views, or to smell the aromatic herbs that grow all over the island, are wonderful experiences in themselves.
There are many possibilities for hiking in Alonnisos, as many of the old donkey paths are kept open, and most of the areas of the island are easy to reach, even with peaks of up to 475 meters.
