Chora is the capital of Alonissos and the most picturesque village on the island. It is sitting on a hilltop overlooking the Aegean Sea. Chora alone is a good reason to visit the island. Seeing Chora today it is difficult to imagine that it was ever damaged by a major earthquake in 1965. This earthquake caused the inhabitants to move to Patitiri, the port of Alonissos. Along with Chora, the countryside of the island has many beautiful villages, like seaside Votsi, Patitiri, Steni Vala, and Rousoum Gialos. These little villages are all ideal for families and couples.

Thanks to its proximity to the rest of the islands of the Sporades, Alonissos is a great base for island hopping to nearby islands, such as Skopelos or Skyros!
