Just a short drive from Karlovasi, you'll find Potami, a stunning pebble beach where the lush green cliffs meet the crystal-clear Aegean Sea. Forget sand; the smooth, multicolored pebbles are part of its unique charm, and the water is refreshingly deep and clear, perfect for a swim. Stick around for the sunset, as it's one of the best spots on the island to watch the sun dip below the horizon, then grab a drink at one of the relaxed beach bars nearby.
