Perissa Beach

Perissa Beach stretches along Santorini's southeastern coast for an impressive 7 kilometers, making it the island's longest stretch of volcanic black sand. The dramatic landscape puts you right beneath Mesa Vouno mountain, with the ancient ruins of Ancient Thira visible on the cliff above. You'll find organized beach sections with sunbeds (EUR 15-25 including a drink), water sports rentals, and beach bars playing everything from Greek pop to electronic music.

The beach has a distinctly relaxed, international vibe that feels more like a proper seaside resort than Santorini's posher spots. Groups of backpackers mix with Greek families, while beach volleyball games happen spontaneously near the water sports centers. The black sand gets scorching hot by midday, so most people stick to the sunbeds or rush quickly between towel and sea. The water stays surprisingly clear despite the dark sand, and you can walk out quite far before it gets deep.

Most travel guides oversell this as a budget paradise, but sunbed prices have crept up significantly in recent years. The southern end offers genuinely free space if you don't mind walking 10 minutes past the last taverna. Skip the overpriced water sports here and save money for better operators in Kamari. The beach gets packed between noon and 4pm, so come early or late for a better experience.
