Miami to Key West Day Trip: Tips & Practical Info
1. Leave EARLY. Departures before 7 AM avoid worst traffic.
2. Avoid weekends if possible. Saturday especially can add 1–2 hours each way to the drive.
3. Pack: swimsuit, sun protection, comfortable walking shoes, water bottle. Key West gets hot in summer.
4. Cash for tolls, tips, and small purchases. $50 in cash is a smart cushion.
5. Driving back: don’t stop unless very tired. Save sleep for Miami arrival. The drive home is the hardest part.
6. Consider an overnight if you can. One-day round trips from Miami are exhausting. Even one night in Key West dramatically improves the experience.
7. Avoid hurricane season (Aug–Oct). Tropical storms occasionally close the Overseas Highway.
