Top places for family water fun
Families should head to Crandon Park at Key Biscayne for calm waters, picnic spots, and shallow shores. Matheson Hammock Park’s man-made atoll is stroller-friendly and safe for kids to splash. The Miami Children’s Museum and nearby boat tours also tailor experiences for little ones, while family-friendly snorkeling can be found off Biscayne National Park with calm, clear waters.
Types of boats to rent in Miami
Miami’s marinas offer an array of rental options: nimble center consoles for fishing; luxury yachts for parties or special occasions; sporty speedboats for island-hopping; sailboats for a tranquil day under wind power; pontoons for relaxed group outings; and jet boats for high-energy thrills. Many operators provide captains if you prefer to be a passenger.
Best beaches and marinas
South Beach remains iconic for people-watching and water sports, but quieter gems like Haulover Beach, Crandon Park Beach, and Bill Baggs Cape Florida State Park offer more space and family amenities. For dockside service and boat access, try Miami Beach Marina, Bayside Marketplace docks, or the full-service Dinner Key Marina in Coconut Grove.
Vacation tips for maximum water fun
Book high-demand activities (parasailing, dolphin tours) in advance, especially during winter. Pack reef-safe sunscreen and a waterproof phone case. If you’ll be on boats, bring light layers — sea breezes can be cool at sunset. For families, choose activities with lifeguards or certified guides. Check weather and tide conditions before setting out, and consider travel insurance for expensive charters.
Miami mixes glamour, wild nature, and endless sunshine. Come ready to jump in, glide, and explore — whether you’re chasing thrills or a peaceful paddle, the city’s waterways are waiting.
