Coco Plum Beach

Coco Plum Beach represents Marathon’s best-kept secret, a quiet stretch of natural shoreline that locals treasure for its peaceful atmosphere and lack of development. Tucked away in the Coco Plum neighborhood, this beach doesn’t advertise itself with big signs or facilities, which is exactly how the community prefers it. The beach features a more natural Keys environment than the manicured Sombrero Beach, with seagrass beds, rocky patches, and small sandy areas creating diverse coastal habitat. The calm, protected waters remain shallow for a considerable distance from shore, making it ideal for families with small children or anyone seeking gentle swimming conditions.

The secluded nature of Coco Plum Beach creates an experience quite different from the more popular Marathon beaches. You won’t find volleyball courts, concession stands, or crowds of spring breakers here—instead, you’ll discover local families teaching their children to swim, dedicated anglers casting from shore, and couples enjoying peaceful beach walks. The sunrise views over the Atlantic Ocean are spectacular, with the eastern exposure providing stunning colors as the sun emerges from the sea. Snorkelers who venture to the rockier areas on either side of the beach can spot tropical fish, crabs, and other marine life, though this isn’t a premier snorkeling destination like some other Keys beaches.

The beach’s minimal facilities reflect its status as a neighborhood beach rather than a tourist attraction. Basic restrooms are available, but visitors should bring everything they need for a beach day. The small, unpaved parking area accommodates only a limited number of vehicles, which naturally controls crowds and preserves the tranquil character of the beach. Local residents appreciate respectful visitors who pack out their trash, keep noise levels down, and treat this hidden gem with care. For travelers seeking an authentic, uncrowded beach experience in Marathon without the entrance fees of state parks, Coco Plum Beach offers a perfect escape where the only sounds are waves gently lapping the shore and seabirds calling overhead.
