Visas & entry
A guide to Koukounaries, Skiathos's most popular beach, acknowledges it gets genuinely packed with boat-tour crowds in summer, but notes deserted coves are often just a short hike away for anyone willing to walk past the main stretch of sand. Their timing tip: come in the late afternoon once the tourist boats have departed back to Skiathos Town, when the crowds thin out and the beach settles into a quieter scene for sunset.
