Florida Keys in Winter: a Six-Day Overseas Highway Road Trip

A scenic road, with time off the road

Start and finish at Miami International Airport (MIA): six days, five nights, about 600–650 km including local driving. FHWA designates the Florida Keys Scenic Highway an All-American Road. That is a scenic-road designation, not a claim of the most bookings. Best for two drivers or one driver comfortable with bridges and slow traffic; families can replace kayaking with beach time.

The itinerary is about the Keys, not another Miami city break. Two nights in Key West avoid a long drive immediately before a timed water activity.

January climate and road planning

NOAA’s Key West airport normals for January (1991–2020) are a 24.3°C average daily high, 18.6°C low and about 46 mm of rain. Winter days offer roughly 11 hours of daylight. December–April is the local dry season, but cold fronts can bring wind and rough water. These historical patterns do not predict your six travel days.

Pack sun protection, a windproof layer, water shoes and a dry bag. Schedule bridge crossings in daylight. This low-elevation coastal route is chosen over snow-prone mountain roads; January construction, closures and weather restrictions are not yet confirmed. Check FL511 before each driving day and follow closures rather than searching for an improvised detour. Summer is hotter and wetter; tropical-storm disruptions require different planning.

Six days, five nights

Planning estimates, not live navigation: the main segments total about 570 km, rising to 600–650 km with local detours; allow about 9–11 hours of pure driving across the trip. Meals, parking, queues and bridge congestion are extra. Use your hotel addresses for final routing.

Day 1 · A gentle start in Key Largo

Collect the car, buy water and reach Key Largo before dark. If arrival allows, take a short shore visit at John Pennekamp; otherwise shift it to the next morning. Current park hours are 8am to sunset. Reef boats and snorkeling are separate, weather-dependent bookings, not included here.

Day 2 · Islamorada and the old bridge

Pause in Islamorada for lunch and a waterfront break, then continue to Marathon. Allow 45–60 minutes for an out-and-back on the open pedestrian part of Old Seven Mile Bridge. You do not need to walk the full 2.2 miles to Pigeon Key; turn around early and never stop your car on the active highway bridge.

Day 3 · Bahia Honda, then Key West

Leave the morning for Bahia Honda’s shore and views, around two to three hours, before continuing to Key West. Current park hours are 8am to sunset; swim only where conditions and signs allow. Check in, leave the car, and take an easy evening walk near the historic seaport.

Day 4 · Mangroves or an easy shore day

Take the optional two-hour kayak tour only if conditions and your abilities suit it; arrive 30 minutes early. Keep the afternoon unbooked for Old Town, lunch and rest. If wind cancels the outing, use cafés and a short land-based walk rather than replacing it with another sea trip.

Day 5 · Return north without a deadline

Drive back along US 1, revisiting only a favorite stop. Sleep in Homestead to reduce the next morning’s airport drive. A late departure can add traffic pressure; start after breakfast and do not promise yourself a fixed arrival hour.

Day 6 · Rental return and flight

Refuel or recharge according to the rental contract and allow separately for airport traffic, car return, transfers and airline check-in. For an early morning flight, replace the Homestead night with an airport hotel and make Day 5 the longer drive.

Optional mangrove kayak experience

Key West Mangrove Kayak Eco Tour · 4.9/5 · 2,387 reviews (Viator + Tripadvisor combined; checked 7 October 2026). Viator displayed from US$80 per person, about two hours; January inventory is unconfirmed. Recent September–October feedback likes the guides and ecology, while a booking-communication complaint makes reading the confirmation especially worthwhile.

Lazy Dog Adventures provides the guided kayak outing. Meet at 5114 Overseas Highway, Hurricane Hole Marina, 30 minutes early; return to the same marina. Bring water; bottled drinks, dry-bag rental and optional tips are extra. Parking is very limited, so consider a taxi from your hotel. You must know how to swim; check fitness and accessibility restrictions before booking. Wildlife sightings are never guaranteed.

Compare channels: the operator’s page currently displays US$70 adult admission and a 12-hour cancellation cutoff; Viator lists at least 24 hours for a full refund. These are different displayed terms, not a guaranteed like-for-like final-price comparison. Confirm date, taxes, inclusions and channel-specific cancellation rules before payment.

Hotels, rental cars and the RV alternative

Stay one night each in Key Largo and Marathon, two in Key West, and one in Homestead. In Key West, compare Old Town walkability against hotel parking charges; Stock Island can work if you budget transfers. A compact rental car plus hotels is the default. Check total rental taxes, toll administration, insurance, driver eligibility and parking dimensions.

Compare rental cars · Explore RV rentals

An RV replaces the car-and-hotel plan; do not book both. First secure campgrounds and check vehicle length, hookups and access. Bahia Honda’s Bayside access has a 6 ft 8 in clearance: a tall RV cannot use it. We have not checked campsite inventory. Rental insurance, mileage and pet rules vary; no saving is promised. EV drivers should verify working chargers at overnight stops and allow a reserve rather than rely on one fast charger.

Confirm before setting out

Recheck park alerts, campground access and FL511 a week before departure and each driving morning. January 2027 future road status and activity inventory cannot be guaranteed today. Do not drive through flooded roads. Use designated parking, keep valuables out of sight and never handle wildlife. If the kayak outing is unsuitable, omit its cost and enjoy the shore; a boat booking is not essential to this road trip.

Per-person budget

6 days / 5 nights. Every figure and input below is one adult’s full-trip share. Accommodation assumes a room shared equally with one companion; shared transport or vehicle costs use the same split. Solo travellers should replace these shares with their own full room and vehicle costs.

Planning allowances, not live quotes. International flights, visas, insurance and shopping are excluded. Replace with your actual tax-inclusive per-person amounts; remove meals or admissions already included in a tour.
