Pine forest, clear coves and the heart of Greece's first marine park.
Alonnisos combines a restored hill village, quiet beaches and access to protected monk-seal habitat in the National Marine Park.
Alonnisos is the inhabited base for the National Marine Park of the Northern Sporades, created to protect Mediterranean monk seals, seabirds and marine habitats. Patitiri's information centre and responsible boat trips explain the ecosystem without promising wildlife encounters.
Old Alonnisos, or Chora, was rebuilt after the 1965 earthquake and now overlooks a pine-covered island of paths and coves. Steni Vala retains a small fishing harbour, while the underwater museum at the Peristera shipwreck adds pioneering dive access.
