Matheson Hammock Park: Atoll Pool Status, Fees and Rules

Matheson Hammock Park is the bayfront park on Old Cutler Road that most people know for one thing: the atoll pool, a ring of sand around a saltwater pool that Biscayne Bay fills with every tide. Miami-Dade County calls it the county’s first park, and it’s bigger than the beach suggests, with a busy marina, kayak and kiteboarding access, a coral rock restaurant building, and a hardwood hammock on the other side of the road.

The thing to know before you drive down in 2026 is status, not scenery. The atoll pool closed after a June 13, 2026 fish kill, but Miami-Dade County’s current park page now lists the lagoon as open seven days a week. Because operating hours can still change for water quality, wildlife, or other conditions, check the county page or call ahead if swimming is the main reason for your visit. The west side of the park across Old Cutler Road has also been closed for a restoration project. I’ll lay out the current status, then the fees, the rules that catch people at the gate, and how I’d plan a visit.

Is Matheson Hammock open right now?

Mostly. One part of the park is still closed, and the atoll pool is back on the county’s open list after a summer closure. A lot of people ask why Matheson Hammock is closed, and in 2026 the honest answer depends on which part you mean.

June pool status from Coral Gables Gazette reporting with Miami-Dade County comments (June 22, 2026). Current lagoon wording and other details from Miami-Dade County Parks pages, checked October 12, 2026.

The county’s current Matheson page says the lagoon is open seven days a week and publishes regular pool hours, and it also notes that those hours can be affected by wildlife, natural disasters, or water quality. That second line is the reason I’d still check before a swim-focused trip. The marina office number on the county’s page is 305-665-5475, and the Miami-Dade Parks main line is 305-755-7800. Ten minutes on the phone is cheaper than a weekend parking fee for a beach you can’t swim at.

Fees, hours, and how to pay

Fees as listed on Miami-Dade County’s Matheson Hammock Park page, checked October 12, 2026.

You pay through the Pay-By-Phone or ParkMobile app, or in person at the park office. Miami-Dade’s park information page lists Matheson Hammock from sunrise to sunset, with the park office open 8 a.m. to 5 p.m. daily. The county separately lists the boat ramp from sunrise to sunset. If you’re local and come more than a couple of times a month, the annual pass math works quickly; for a single visit, I’d go on a weekday, when the parking is $3 cheaper, though the trade-off is that lifeguards only staff the pool on weekends and holidays.

Atoll pool hours

• Summer: Monday to Friday, 9 a.m. to 5:30 p.m.; Saturday and Sunday, 9 a.m. to 6:30 p.m.
• Winter: Monday to Friday, 9 a.m. to 4:30 p.m.; Saturday and Sunday, 9 a.m. to 5:30 p.m.
• Lifeguards: Weekends and holidays, according to the county.

The county doesn’t say when the summer and winter schedules switch, so if you’re cutting it close to closing time in spring or fall, assume the earlier hours.

How the park is laid out

Old Cutler Road splits Matheson Hammock into two very different places. The west side, about 109 acres that the county calls West Matheson, is mostly protected natural forest, nearly 90 percent of it designated as a Natural Forest Community. The east side is where you pay to park and drive in toward Biscayne Bay: the park road runs through hammock and mangroves to the bayfront, where the atoll pool, the beach, the coral rock restaurant building, and the marina sit. Fairchild Tropical Botanic Garden is just south on Old Cutler Road at 10901 Old Cutler Road.

Because the bay is to the east, the atoll beach is a sunrise-facing spot. In the evening the light comes from behind you, over land, rather than setting over the water, and the park closes at sunset, so I’d plan photos for the last hour rather than the last minute.

The atoll pool: how it works and who it suits

The atoll pool is the park’s signature. Landscape architect William Lyman Phillips, hired in 1936, dredged the area to create a protected saltwater pool that projects into the bay and is fed by the tides. The result is a ring of sandy beach around water that’s more sheltered than open Biscayne Bay.

That doesn’t make it a swimming pool. The water is bay water, it changes with the tides, and Miami Waterkeeper samples it weekly and posts the results to Swim Guide, where the site has historically passed water quality tests 60 to 95 percent of the time. I’d check Swim Guide before a visit, but look at the date of the latest sample as well as the pass/fail status. Miami Waterkeeper describes the site as weekly monitored, although the displayed result can be several days old. With younger kids, I’d pick a weekend or holiday, when lifeguards are on duty, over a cheaper weekday when they aren’t.

• No flotation devices on the beach. The county cites its park rules on this, so leave the pool floats at home.
• No tents, barbecue grills, cooking, or open flames in the beach area.
• No glass beverage containers on any county beach.

Beyond the pool: marina, paddling, kiteboarding, and the hammock

Matheson Hammock is home to the county’s second-largest county-operated marina, with room for about 330 boats of 30 to 50 feet in wet slips and dry storage, 11 boat-launch lanes, a fuel dock, pump-out facilities, a bait-and-tackle shop, and a Miami-Dade Sheriff’s Office Marine Patrol station. The ramps are reached by the same park road you drive in on, so expect boat trailers sharing it on a nice weekend and give yourself a few extra minutes.

• Kayaks and paddleboards: PADL runs a self-service kiosk in the park for kayak and paddleboard rentals.
• Kiteboarding: The county lists kiteboarding as available at the park.
• Wi-Fi: Free on and near the boat docks, on the network MathesonMarinaGuest.
• Hammock trail: Florida Hikes describes a 1.4-mile footpath in two parts on opposite sides of Old Cutler Road. The East Hammock Trail starts near the kiosk at the parking area closest to the park entrance; the West Hammock Trail is on the west side, which the county closed for its restoration project.

Food, picnics, and shelters

The restaurant in the historic coral rock building is now NOMA Beach at Redfish, Donatella Arpaia’s Italian-inspired waterfront restaurant, which the county lists as open Wednesday through Sunday. Hours vary by day, so I’d check before planning a meal around it, especially on a Monday or Tuesday, when it’s closed.

For a picnic, the county rents a Coral Rock Shelter for up to 75 guests at $300 plus tax and Tiki Shelters for up to 25 guests at $150 plus tax, a setup that suits birthday parties and small celebrations. Under Miami-Dade Parks rules, alcohol is allowed only at picnic shelter areas or other designated areas, from noon to sundown. With grills banned on the beach, I’d bring food that doesn’t need cooking or plan on the restaurant.

Rules that catch people at Matheson

• Pets: The county’s Matheson page says pets aren’t allowed. Service animals are an exception under county park rules.
• Drones: Miami-Dade park rules prohibit taking off or landing aircraft or other aerial apparatus on park land or waterways without written permission from the department director. If you plan to fly a drone, confirm the current county and FAA requirements first.
• Beach area: No tents, grills, open flames, flotation devices, or glass.
• Hours: Sunrise to sunset for the park, with separate atoll pool hours.

A little history

The county describes Matheson Hammock as Miami-Dade’s first park. William J. Matheson donated about 85 acres of beachfront land for a park in 1930, according to The Cultural Landscape Foundation, and Phillips’s design was carried out with the Civilian Conservation Corps, whose crews built the coral rock structures that still define the park. The park has grown far beyond that original donation, with large areas of mangrove and hardwood forest surrounding the bayfront facilities, which is why it feels so much bigger than the beach.

Getting there, and pairing it with Fairchild

Matheson Hammock is at 9610 Old Cutler Road, and Fairchild Tropical Botanic Garden is just south at 10901 Old Cutler Road, which makes the two an easy pairing. You may also see 5400 SW 96th Street on one Miami-Dade park listing, but 9610 Old Cutler Road is the address the City of Coral Gables, the state’s Florida Birding Trail, and NOMA Beach at Redfish use, and it’s the one I’d put into a map app for the bay side of the park. Old Cutler Road is a scenic, mostly two-lane road, so I’d check live traffic rather than trust a fixed drive time, especially on weekend mornings. For cyclists, the Old Cutler Trail, a 13.6-mile paved path according to TrailLink, runs past both.

If I were planning one day here, I’d do Fairchild in the morning, while the garden paths are cooler, then move to Matheson in the afternoon for the bay side, the marina, and an early dinner at NOMA Beach on a day it’s open. If swimming is the point, flip it: arrive when the pool opens at 9 a.m., swim before the midday heat, and save Fairchild’s shade for the afternoon. Either way, check the pool’s status that morning before you choose which half of the day it gets.

Matheson Hammock Park FAQ

No. Parking is $7 plus tax per car on weekdays and $10 plus tax on weekends and holidays. Buses and RVs pay $15 plus tax per day, and the Miami-Dade Annual Park Pass ($165 plus tax, or $50 plus tax for seniors 62 and older) covers parking but not the boat ramp.

The part that’s closed is West Matheson, the forested west side across Old Cutler Road. As of October 2026, Miami-Dade’s current West Matheson page still lists the area as closed for restoration and says the project is expected to be completed by fall 2026, but no reopening date is posted. The atoll pool closed after a fish kill on June 13, 2026, but Miami-Dade County’s current park page now lists the lagoon as open seven days a week. The marina, boat ramps, and restaurant are listed as operating.

Yes, according to Miami-Dade County’s current Matheson Hammock Park page, the lagoon is open seven days a week. It had closed after a June 13, 2026 fish kill and was still closed on June 22.
