Plongée à Alonissos Marine Park — Greece

The National Marine Park of Alonissos protects the critically endangered Mediterranean monk seal along with pristine Aegean reefs. Strict permit limits keep diver numbers low, and the underwater archaeology — including ancient shipwrecks — adds historical depth. The pine-forested Sporades islands are among Greece's loveliest.
