A long, undeveloped sandy beach on the northeast Attica coast near the historical site of the Battle of Marathon. The water is clean, the beach is rarely crowded, and it makes an excellent addition to a Marathon historical site visit.
Marathon Beach extends along the northeastern coast of Attica in the municipality of Marathon, approximately 42 kilometres northeast of central Athens. The beach sits on the calmer Euboean Gulf side of the Attica peninsula rather than the Saronic Gulf, giving it characteristically different water conditions — generally calmer, warmer, and with less movement than the western Attica coast. The shoreline is long, wide, and undeveloped by Riviera standards, composed primarily of pale sand with a gentle gradient into shallow water. The absence of large organized beach club infrastructure is one of Marathon Beach's defining features: the beach feels open, natural, and unhurried, with only seasonal beach bars and basic facilities appearing during summer months. Marathon is positioned close to the famous plain of Marathon, where the Battle of Marathon was fought in 490 BC — one of the defining military engagements of ancient Greek history. The Marathon Archaeological Museum and the burial mound of the Athenian fallen soldiers (the Soros) are within a few kilometres, making Marathon Beach the foundation of an unusual day trip combining history and the sea. The nearby Marathon Reservoir, constructed in the early 20th century and faced in Pentelic marble, is also worth a visit. Water quality at Marathon Beach is consistently good — the northeastern coast of Attica is less affected by Athens metropolitan activity than the Saronic Gulf beaches to the southwest. The KTEL bus service from the Mavromataion terminal in central Athens covers the route in approximately 60 minutes. Private car access along the main road from Athens is straightforward. The beach rarely reaches the overcrowded conditions seen at Riviera resorts in peak season, retaining a relaxed and genuinely peaceful character throughout summer.

Accessibility
Marathon Beach has flat, wide sandy access from roadside parking areas. The gradual sandy gradient makes entry straightforward for most visitors. No formal adapted facilities or beach wheelchair hire is confirmed.
