The National Marine Park of Alonissos Northern Sporades, Greece's largest working marine protected area, offers pristine waters teeming with marine life. Divers and snorkellers can observe huge groupers, colourful wrasse, and other species in the protected reef of Agios Petros. The park, established in 1992, has successfully preserved biodiversity, making it an ideal destination for underwater enthusiasts.
A new citizen science project, the Highly Protected Mediterranean Initiative, invites visitors to participate in logging native and alien species. Partnering with local dive centres like Ikion Diving and universities, the project provides free snorkelling and diving trips to collect data on marine life. Participants use dive slates to identify fish, contributing to research while enjoying the sea.
For history buffs, the Peristera wreck, an underwater archaeological site from the 5th century BC, offers a glimpse into ancient trade routes. Certified divers can explore the cargo of amphorae with accredited centres. On land, Alonissos boasts lush landscapes with Aleppo pines and oaks, hiking trails, and charming harbours like Steni Vala.
Local seafood tavernas such as Tassia's Cooking and Margarita serve freshly caught fish, including Alonissos tuna and scorpion fish. Accommodation options like Ilya Botanic Suites provide minimalist rooms with plunge pools amidst olive groves. The island's combination of underwater wonders and terrestrial attractions makes it a unique Greek destination.
