Cons: Shared shuttles can be slower; private shuttles are more expensive than a standard rideshare.
Recommended Providers: Companies like SuperShuttle (shared), GO Shuttle, and MIA-approved ground transportation offer reliable service. Always book directly through the company's official website.
Rental Car: Ultimate Flexibility
Renting a car is best if you plan to explore beyond Key Biscayne (e.g., the Everglades, South Beach, the Florida Keys).
Key Considerations:
- Pickup: All major rental companies (Hertz, Avis, Enterprise, etc.) have facilities at MIA and FLL. Free shuttles take you from the terminal to the rental center.
- Route: From MIA, take FL-836 E to I-95 S, then exit onto the Rickenbacker Causeway (SR-913). A toll ($1.75) is collected via SunPass or Toll-by-Plate. Ensure your rental agreement includes toll handling.
- Parking in Key Biscayne: This is the main challenge. Most hotels have parking (often for a daily fee of $25-$40). Street parking is limited and often requires a residential permit. Confirm parking arrangements with your accommodation before renting.
- Cost: Daily rental rates vary from $30-$100+ per day, plus insurance, fuel, tolls, taxes, and parking fees.
Verdict: If your entire vacation is on Key Biscayne, a car is an unnecessary expense and hassle. For multi-destination trips, it's invaluable. Use price comparison sites like Kayak or Autoslash to find the best deals.

Traveler Tips & Local Insights
Master the Rickenbacker Causeway:
This scenic bridge is your only road to Key Biscayne and a major bottleneck.
- Peak Traffic: Weekday afternoons (3:30-7 PM) and weekend mornings/evenings are worst. Add 20-30+ minutes to your trip.
- Tolls: The $1.75 toll is only collected when entering Key Biscayne (westbound is free). Have cash or ensure your rideshare/taxi includes it.
- Scenic Stops: Consider asking your driver to briefly pause at the William M. Powell Bridge vista for a classic Miami skyline photo.
Luggage & Special Needs:
- Surfboards/Bikes: Not all taxis or Ubers can accommodate these. Book an XL vehicle or a shuttle service in advance and call to confirm.
- Accessibility: Miami-Dade taxis are required to have wheelchair-accessible vehicles (WAV). Request one at the taxi dispatch. For rideshares, use the UberWAV or Lyft Access mode in the app (availability may be limited).
Arriving at Fort Lauderdale (FLL):
Your trip will be longer (45-75 mins) and more expensive. Rideshare is almost always cheaper than a taxi from FLL. Consider the shared shuttle option if traveling solo. For groups, a private shuttle may be cost-effective.
Final Recommendation:
For a seamless start to your vacation, book an Uber/Lyft or a private shuttle in advance. The small premium over public transit is worth the time and comfort saved, especially after a long flight.
