Great Sand Beach (also known as Megali Ammos) in Marmari is a world-class destination celebrated for its “shape-shifting” beauty and vibrant surf culture.

The “Shifting” Sand Tongue

• The beach’s most famous feature is a long, narrow strip of fine sand and white pebbles that stretches into the emerald sea. Reviewers frequently marvel at how the beach changes its shape every season (sometimes even weekly), as waves and currents sculpt the sand into different curves, lagoons, or a “horseshoe” shape.

Atmosphere & Scenic Beauty

• Wild & Majestic: It offers a raw, natural landscape that was famously featured in the Greek Ministry of Tourism’s international advertising campaign.
• Water Quality: The water is praised for being exceptionally clear and deep blue. It can get deep quickly, which appeals to experienced swimmers but requires caution.
• Winds: The area is subject to the Meltemi (strong northern winds). This creates a refreshing atmosphere but also means the sea can get choppy.

A Paradise for Water Sports

• Reviewers highlight the beach as a top-tier spot for windsurfing and kitesurfing. Due to a geographical phenomenon known as the Venturi effect, the winds here are consistent and powerful, attracting enthusiasts from across Europe. Even if you aren’t a surfer, the “free show” provided by the colorful kites in the sky is often mentioned as a highlight.

Facilities & Tips

• Largely Unorganized: To preserve its natural beauty, the beach is mostly unorganized. There is plenty of open space to set up your own umbrella, though some seasonal spots may offer a few sunbeds.
• Accessibility: It is located about 2.5 km from the port of Marmari. While reachable by car, the final stretch involves a dirt road that can be a bit rugged.
• Suitability: Because of the strong currents and wind on gusty days, it is better suited for active travelers and watersports enthusiasts than for families with very young children.
• Nearby Dining: For a full meal, visitors usually head back to the picturesque tavernas and cafes along the Marmari waterfront, just a short drive away.
