Salonikios Beach sits on the southern side of Thassos and has a rougher, quieter feel than the island's more organised resort beaches. The mix of sand, stones, low rocks, and clear water makes it a good choice when you want swimming without committing to a heavily serviced beach club scene.
Bring what you need and do not expect the polished convenience of Golden Beach or Paradise Beach. Its appeal is the opposite: a more relaxed patch of coast where the island still feels open and a little unarranged.
