The best snorkeling near Miami: where the reefs actually are, and how to reach them
Miami's beaches are not reef beaches. Here is where to snorkel instead: Biscayne National Park, the ReefLine, Key Largo and a shore reef in Broward.
En bref
- Closest real reef: Biscayne National Park, by boat only; tours from $115 (October 2026).
- From the sand: Lauderdale-by-the-Sea: three reefs within 100 yards, about 10 ft deep.
- In South Beach: The ReefLine sculptures, about 820 ft off 4th to 5th St; no lifeguards there.
- Classic day trip: John Pennekamp, Key Largo: snorkel tour $49.95 adult, $45.95 under 18.
- The rule: Snorkelers need a divers-down flag in Florida and must stay within 300 ft of it.
For the best snorkeling near Miami, take a boat into Biscayne National Park from Coconut Grove or Homestead; if you want to walk in from the sand, drive north to Lauderdale-by-the-Sea.

Biscayne National Park: the best snorkeling inside Miami-Dade
Biscayne National Park's reefs and wrecks are reached by boat only. There is no entrance fee. If you do not have a boat, the park's partner, the Biscayne National Park Institute, runs the trips.
The shortest ride from the city is the half-day snorkel from Dinner Key Marina, 3400 Pan American Drive in Coconut Grove: $115 per person on a shared boat, 3.5 hours, ages 8 and up. It leaves at 9:15 am from June 1 to October 31 and at 1:30 pm from November 1 to May 31; arrive 30 minutes early. A snorkel vest is included and must be worn. Mask, fins and snorkel are not: the bundle rents for $16, and fins are required for everyone in the water.
The captain picks the site each day from the weather and sea state, so you may get a reef, a mangrove shoreline or a wreck. The park's Maritime Heritage Trail has six mapped wrecks with mooring buoys. Three of them, the Erl King, Alicia and Lugano, suit scuba divers; the Mandalay, a schooner that ran aground on Long Reef on New Year's Day 1966, is the one the park singles out for snorkelers. Snorkeling is also good around the base of Fowey Rocks Lighthouse, built in 1878, though the structure is closed to the public.
Biscayne National Park Institute
The nonprofit partner that runs the park's guided boat trips. From Homestead the Snorkel Experience is from $115 for 3.5 hours; a 6-hour snorkel-and-paddle or sail-paddle-snorkel day is from $209, and the same $209 buys a 6-hour snorkel and island visit from Coconut Grove.
The visitor center in Homestead is open daily 9 am to 5 pm. Coconut Grove is the shorter drive from Brickell or Miami Beach; Homestead is closer if you are combining the trip with the Everglades.
The ReefLine off South Beach
The ReefLine is an underwater sculpture park and artificial reef planned to run along Miami Beach. Its first installation, Concrete Coral by Leandro Erlich, is 22 life-size concrete cars lowered in October 2025 and seeded with coral. The ReefLine's own visit page says it is permanently open and free, with the beach entrance between 4th and 5th Street, orange buoys marking the site about 820 feet offshore and about 20 feet of water.
Read the warning on the same page: the site is beyond the protected swim area and is not watched by lifeguards. Twenty feet is deep for snorkelers, and the swim out is long. The safer way to see it is the ReefLine's own guided trip, a two-hour Art and Science Discovery outing for up to 20 guests with snorkel or scuba gear included; there is no price online, so email welcome@thereefline.org.
Two drives worth making: Key Largo and Lauderdale-by-the-Sea
John Pennekamp Coral Reef State Park in Key Largo is the classic. The park concession runs 2.5-hour snorkel tours at 9:00 am, 10:30 am, noon, 1:30 pm and 3:00 pm, with about 45 minutes on the boat each way and about an hour in the water. Tours are $49.95 for adults and $45.95 under 18; a safety vest is free, and masks and fins are $5 each on a snorkel trip. Florida State Parks lists admission at $8 per vehicle plus 50 cents per person (we read that page through search, because the site blocks fetching).
Lauderdale-by-the-Sea in Broward County is the shore option. The town's tourism site puts three coral reefs within 100 yards of the beach in about 10 feet of water, entered at Datura Avenue and El Mar Drive just south of Anglin's Pier. The Shipwreck Snorkel Trail there has an anchor, five concrete cannons and a ballast pile. The beach is open sunrise to sunset, with metered parking on the side streets or at the South Ocean Lot, 4324 State Road A1A. The SS Copenhagen wreck, less than a mile out in about 25 feet, needs a boat.
Before you get in the water
- Florida requires a divers-down flag for snorkelers as well as divers: at least 12 by 12 inches when shown from the water, 20 by 24 inches from a boat
- Stay within 300 feet of your flag in open water and 100 feet in rivers, inlets and channels; boats must idle inside those distances
- On Biscayne tours fins are mandatory, so rent them ($6 alone, $16 with mask and snorkel) or bring your own
- Shared Biscayne trips are for ages 8 and up; private boats take all ages
- Book a morning trip in summer and an afternoon trip in winter: that is how the Coconut Grove departures are scheduled
- Do not swim out to the ReefLine alone; it is outside the guarded area
