Created to protect the endangered Mediterranean monk seal and rare sea birds, the National Marine Park of Alonnisos is the largest in Europe running 2,260 sq km. Although the shy monk seal is rarely seen, you can find three different species of dolphins, turtles and migrating whales.
Skiathos is blessed with some of the most exquisite sandy white beaches, counting 65 in total, including the 1,200 km-long Koukounaries Beach, and a few nudist beaches named Big Banana and Little Banana, highly popular amongst the LGBTIQ community.
