Crandon Park Beach

Crandon Park Beach on Key Biscayne is widely considered the best family beach in the Miami area, and for good reason. A natural sandbar creates a shallow, calm lagoon between the shore and the bar, giving families a protected swimming area where even toddlers can wade safely in warm, clear water.

The beach stretches two miles along the Atlantic side of Key Biscayne, with wide expanses of white sand that never feel overcrowded. Unlike South Beach, which is oriented toward nightlife and aesthetics, Crandon Park is built for families -- a large playground sits behind the beach, picnic pavilions with grills are scattered throughout the park, and the overall atmosphere is relaxed and kid-centric.

At low tide, the sandbar becomes partially exposed and kids can wade out to it, feeling like they have discovered their own island. The water between the shore and the bar stays knee-deep to waist-deep for most kids, making it the ideal depth for splashing, floating, and building confidence in the ocean. Parents can stand comfortably while supervising.

Beyond the beach, Crandon Park encompasses 808 acres including mangrove wetlands, nature trails, a marina, and the Crandon Park Visitors and Nature Center. The south end of the beach has rocky areas where tide pools form at low tide -- kids can spot small fish, crabs, hermit crabs, and sea urchins. Bring snorkel gear for older kids to explore the shallow reef.

Access is via the Rickenbacker Causeway from Miami, which crosses Biscayne Bay with scenic views. Parking is $7 per vehicle and is the only cost. The park is part of Miami-Dade County Parks and is well-maintained with restrooms, showers, and changing areas along the beach.
