Coco Plum Beach

Located in the Middle Keys at Mile Marker 54.5, Coco Plum Beach is the preferred choice for those seeking a quiet, “off-the-beaten-path” seaside experience. Unlike the more manicured beaches in the area, Coco Plum is a natural, untouched stretch of coastline that emphasizes the raw beauty of the Florida Keys.

The “Natural Beach” Experience

Coco Plum is not your typical “resort style” beach with raked white sand; it is a vital part of the local ecosystem.

• The Shoreline: The beach is long and narrow, bordered by lush wetlands and mangroves. It is perfect for long walks, especially for those who want to avoid the crowds found at Sombrero Beach.

• The Water: The Atlantic waters here are incredibly shallow and calm. You can often walk out hundreds of yards before the water reaches your waist.

• Shelling: Because it is less frequented, Coco Plum is one of the best spots in Marathon for shelling—look for sea glass, small conch shells, and unique driftwood.

Top Features & Amenities

Despite its rugged nature, the beach offers essential facilities for a comfortable day trip:

• Dog Friendly: This is one of the few beaches in the Keys where dogs are officially welcome. They must remain on a leash, and owners are expected to clean up after them.

• Wildlife & Conservation: The beach is a protected Sea Turtle Nesting Site. During nesting season (April 15 – October 31), certain areas may be cordoned off to protect the eggs.

• Facilities: On-site restrooms, a covered picnic pavilion, and an outdoor freshwater shower for rinsing off sand and salt.

• Water Sports: Due to the consistent breeze, this is a prime location for kite surfing and windsurfing. The shallow water also makes it an easy launch point for kayaks and paddleboards.

Local Knowledge & Tips

• Watch the Tides: Because the water is so shallow, swimming is best enjoyed during high tide. At low tide, the water recedes significantly, exposing sandbars and seagrass.

• The “Sargassum” (Seaweed): As a natural beach, Coco Plum does collect seagrass (sargassum) along the shore. While some find the smell earthy, it is a critical part of the beach’s health, providing food and shelter for marine life.

• Bring Your Own Gear: There are no vendors or concession stands on the beach. Be sure to pack your own water, snacks, and shade, as the natural hammock trees provide limited cover during the midday sun.

• Bird Watching: The adjacent wetlands are a magnet for local heron, egrets, and occasional roseate spoonbills. Bring binoculars if you’re a nature lover.

Insider Tip: If the small parking lot is full, don’t park on the side of Coco Plum Drive; the local enforcement is strict. Arrive early or try visiting on a weekday to guarantee a spot.
