Key West voiture calculateur

Driving the Overseas Highway to Key West — 160 miles, roughly 3.5-4 hours of wheel time and realistically a full day with stops — costs a couple about $1,611 for the classic run: two nights in sunset season. It breaks down as the drive $71 ($44 of fuel for 320 round-trip miles at 25 mpg and $3.40/gal, plus $27 of Turnpike tolls and the rental transponder fee), the stay $756 (2 nights × $378 sunset nightly ×1.4), the four marquee stops $154 (Pennekamp, Robbie's, the Turtle Hospital, Bahia Honda), and food $630 across 3 days at $105/person. The one-night dash prices at $1,023 — cheaper, but you'd miss the sunset the whole drive exists for. And the big call: the Dry Tortugas ferry adds $410 for a couple — worth it only if you seriously snorkel.

The drive — fuel + Turnpike tolls + rental transponder$71
Stay — 2 nights × $378 sunset-season$756
Paid stops — 4 of the marquee Keys stops$154
Food — 3 days × $105 per person$630
Dry Tortugas ferry — skipped (★ the money play)$0
And the one-night dash, for comparison$1,023
Total — 2 nights, a couple, sunset season$1,611
VerdictTwo nights minimum is the right pace for the Overseas Highway — one night turns it into a march. The Dry Tortugas ferry adds roughly $400-800 for a family, so take it only if you are serious snorkelers; otherwise the Mallory Square sunset is free.

Trip verdict

This trip prices $1,611 for 2. The zero-night day trip is $435 and the one-night dash $1,023 — cheaper on paper, but you'd miss the Mallory Square sunset the whole highway exists for. The Dry Tortugas ferry would add $410 ($2,021 all-in).

Two nights minimum is the right pace for the Overseas Highway — one night turns it into a march. The Dry Tortugas ferry adds roughly $400-800 for a family, so take it only if you are serious snorkelers; otherwise the Mallory Square sunset is free.

Tip: the best stops order

Southbound in one line: Pennekamp snorkel in Key Largo in the morning (book the earliest slot), Robbie's in Islamorada late morning, the Turtle Hospital in Marathon mid-afternoon then the free Seven Mile Bridge, Bahia Honda for a swim, Key West for sunset. Reverse it on the way home so nothing backtracks.

Warning: hurricane season and the sunset premium

June-November hotels are cheapest but it is official hurricane season (peak mid-August to late October): book refundable rates and watch the forecast — the Keys evacuate first. Dec-Apr you pay ×1.4 for dry air and the sunset, so lock winter rooms 2-3 months out.

Bands are 2026 planning ranges from published prices — not live bookings, and rooms, the ferry and tours move with the calendar: verify before you commit.

FAQ

Can you do Miami to Key West in one day?

Driving, yes: 160 miles and 3.5-4 hours without stops via the 18-Mile Stretch — realistically 6-8 hours with traffic and photo stops — and a zero-night day trip is the cheapest version of this run. But you arrive tired, miss the famous Mallory Square sunset (it fires about 30-45 minutes before sundown) and skip the islands' best hours; that is why the verdict says two nights is the right pace, with one night the honest floor.

What is the best order for the Keys stops?

Southbound in one line, roughly an hour apart: Key Largo first (John Pennekamp snorkel trips leave in the morning — book the earliest slot), Islamorada late morning (Robbie's tarpon feeding), Marathon mid-afternoon (Turtle Hospital tours run on the hour, then the free Seven Mile Bridge view), Bahia Honda for a beach swim, then Key West for sunset. Reverse it on the way home so nothing backtracks.

Is the Dry Tortugas ferry worth $195-210 per person?

Only for committed snorkelers and history buffs: it is a 2-2.5-hour catamaran ride each way with breakfast and lunch included, roughly 7:30am-5:30pm, so it consumes a whole Key West day and adds $390-420 for a couple or $780-840 for a family of four. Fort Jefferson and its reef are genuinely world-class; if nobody snorkels seriously, skip it and take the closer reef trip off Pennekamp for a fraction of the price.

When are Key West hotels cheapest?

Value season (May-November) runs $220-320/night; the December-April "sunset season" lifts the same rooms to $310-450 — a ×1.4 premium for dry, warm weather plus sunset-celebration crowds. Book 2-3 months out for winter weekends, and note that a Miami overnight before or after the drive is far cheaper ($150-280).

Do I need SunPass for the tolls?

The Turnpike/Homestead Extension accepts SunPass, E-PASS, LeeWay and toll-by-plate; a rental car adds a $10-15-capped transponder/admin fee on top of roughly $12 round trip. The scenic alternative via Card Sound Road costs just $1.50-3 and adds 15-20 minutes — worth it once for the drawbridge and the legendary Alabama Jack's at its foot.

Should I fly into MIA or FLL for this drive?

MIA is the right airport: it puts you about 60 miles from Florida City versus 90+ from FLL, and all southbound traffic funnels through the same Stretch regardless. FLL tickets can run $50-100 cheaper — budget the extra 45-75 minutes of highway and an earlier start, and price a Miami hotel night ($150-280) if you land late.

What time is the Key West sunset — and when should I be at Mallory Square?

Sunset swings from about 5:30pm in December to about 8:10pm in late June. The Mallory Square street celebration starts 2-3 hours before sundown; arrive 45-60 minutes early for a railing spot, watch the cruise-ship schedule (port days pack it), and remember the show and the view are completely free — Hemingway House ($18-20) pairs well earlier in the day.

How honest do I need to be about hurricane season?

Very: June 1-November 30 is official season, with the statistical peak from mid-August to late October. That is exactly when hotels are cheapest, and most years you will only meet afternoon thunderstorms — but a named storm can close the Stretch and the Keys are Florida's first evacuation zone, so book refundable rates, watch the forecast the week you drive, and carry travel insurance in August-October.
