Marathon, FL beaches: Sombrero, Coco Plum and Curry Hammock

Marathon has three public beaches we could confirm, and two of them posted no entry fee. The City of Marathon runs Sombrero Beach and Coco Plum Beach. Florida State Parks runs Curry Hammock State Park. Each has a different personality, and Sombrero and Coco Plum share a seasonal rule that visitors from April through October should know. Every hour, fee and rule below comes from the operator’s page as we read it on October 24, 2026.

Sombrero Beach

Sombrero Beach is the family pick. The City of Marathon describes a sandy beach on the Atlantic framing a shady park with picnic pavilions, playgrounds, volleyball courts, restrooms and showers. The City redeveloped it in 2001 for total handicap accessibility. To get there, turn south on Sombrero Beach Road and drive to the end.

The City of Marathon lists Sombrero open Monday through Sunday, 7:00 a.m. to dusk, as posted October 24, 2026. The City’s page posted no entry fee. One practical limit: there are no RV or bus parking spots at Sombrero Beach, so leave the motorhome elsewhere.

Coco Plum Beach

Coco Plum is the more natural of the two city beaches. The City of Marathon describes a beach area with an adjacent wetland, restroom facilities and a covered pavilion. Turn south on Coco Plum Drive; the entrance is 1.4 miles down on the right. The City lists Coco Plum open 7:30 a.m. until dusk, as posted October 24, 2026, with no entry fee posted. As at Sombrero, there is no RV or bus parking.

• Coco Plum Beach in Marathon is a more natural beach area with an adjacent wetland, restroom facilities and a covered pavilion; it is also a turtle nesting beach. Hours 7:30 a.m. until dusk. Turn south on Coco Plum Drive; the entrance is 1.4 miles on the right. No RV or bus parking. City of Marathon: Coco Plum Beach

Sea turtle nesting, April through October

Both city beaches are sea turtle nesting beaches. The City of Marathon says that from April through October, primarily loggerheads come ashore at night to nest at Sombrero. The City surveys the beach for new nests and limits human activity near active nests, which it says typically represent less than 10% of the available beach area. In other words, the beach stays open during nesting season; the marked nest areas do not. Coco Plum is also listed by the City as a turtle nesting beach. Our sea turtle season page explains what changes on the sand during those months.

Dogs in Marathon

The City of Marathon says all of its parks are dog friendly except the Community Park soccer and baseball fields. Dogs must be leashed and owners must pick up after them. Neither beach page posts a separate beach rule, so the citywide rule is the one we can cite. Keep dogs well clear of marked nests in season.

Curry Hammock State Park

Curry Hammock is at 56200 Overseas Highway, Marathon, phone 305-289-2690. Florida State Parks calls it the largest undeveloped parcel of land between Key Largo and Big Pine Key. On calm days paddlers find quiet water there; on windy days the park fills with kiteboarders. It also hosts record numbers of peregrine falcons every fall, worth knowing if you watch birds.

Florida State Parks lists Curry Hammock open 8 a.m. to sunset, 365 days a year, as posted October 24, 2026.

Two fee figures, one park

The two Florida State Parks pages for Curry Hammock differ for groups of three or more. The park’s main page, as posted November 1, 2026, said one person $4.50 and two or more people $6. The park’s hours and fees page, as posted October 24, 2026, gave a longer ladder: one person $4.50, two people $6, three people $6.50 and up to eight people $9, each including a 50-cent Monroe County surcharge per person, with pedestrians, bicyclists and extra passengers at $2.50. The two pages agree for one or two people. We treat the hours and fees page as current and show the other figure so you are not surprised at the gate.
