It never ceases to entertain longtime Miami locals when friends from other cities say things like, “You must go to the beach, like, ALL THE TIME.” Sure, if by “all the time,” they mean “I think once last fall, but I don’t really remember,” then, yes, dead on. Because even though we’re blessed with more year-round public sand than just about any other major city in the union, for some reason we rarely get out there.

Tucked deep down Old Cutler Road, you’ll find Matheson Hammock Park, a thick forest of mangroves and palm trees that ends at one of the most stunning beaches in South Florida. The small, crescent-shaped beach looks like the swaths of sand you only see in stranded-on-a-tropical-island movies, a perfect white canvas backing up to lush vegetation that appears completely untouched by humans.

South of Fifth (SoFi)
Technically, yes, South of Fifth is still considered South Beach. But turning right at the end of the MacArthur Causeway brings you into a far calmer, quieter, and more relaxed stretch of sand. The neighborhood is residential and only sports a handful of ʙᴀʀs and clubs, so the beach itself is not nearly as raucous as ones you’d find north of Fifth. There’s a rock jetty at the end of the beach where you can stroll, and weekends bring cruise ships to the area, creating the eerie sensation of watching a 20-story building float past.

Crandon Park
Miamians know the best beaches in the city lurk across the Rickenbacker Causeway in Key Biscayne. The first you’ll encounter when vᴇɴтuʀιɴԍ over to the scenic landmass is Crandon Park, a pillow-soft slice of paradise that feels like a deserted island. The water here is bright turquoise and calm as a lake, making it a great place to bring smaller kids to swim. There’s also no shortage of paddleboard and kayak rentals, if that’s your bag.

Bill Baggs State Park
The narrow beach feels like you’ve washed up on a marshy island, surrounded by ocean and little else. On a weekday in the summer, you’ll often be the only person here, where you can set up shop under the lighthouse and enjoy the quiet sᴇcʟusιoɴ.

North Beach
The beach is hyper-local, as tourists tend to ignore this expense on their way from South Beach up to Surfside. It’s got a big public parking lot, making it prime territory for making like a local around these parts.
