Florida Keys Road Trip Guide

Two Key West nights for the town and return drive; add a Key Largo night for a reef visit. Old Seven Mile Bridge remains a separate walk.

Key Largo and Reef Start

John Pennekamp Coral Reef State Park is at Mile Marker 102.5, 102601 Overseas Highway. Park concessionaire Coral Reef Park Company offers approximately 2.5-hour snorkelling trips including the boat journey. Check additional check-in time, weather and swimming suitability; this is not a spontaneous short roadside stop.

Non-snorkellers can consider a glass-bottom boat trip, which also goes to sea and is not a bad-weather substitute. On land, the visitor-centre aquarium and short nature trails offer alternatives. In uncertain weather, use open land facilities. The reef is not something you simply walk to from the beach.

Islamorada and Marathon Pause

Islamorada and Marathon are separate places along US 1. Choose one for a meal break; a marina terrace is accessible only where the business admits visitors. Marathon pairs particularly well with a short Old Seven Mile Bridge walk afterward.

If the reef tour finishes on the morning you continue south, keep the Key West transfer to a meal break. Omit extra kayaking or beach programmes rather than turning the transfer into another activity day.

Seven Mile Bridge Timing

Seven Mile Bridge is the clearest visual symbol of the Keys. It is also a place where timing matters because traffic, light and fatigue can change the feeling quickly.

Do not treat the bridge as the end of the plan. It should sit inside a slower day that already has a realistic overnight.

The highway crossing and the walk are separate stops. The accessible stretch of the Old Seven Mile Bridge begins on the Marathon side and runs about 2.2 miles (3.5 kilometres) to Pigeon Key. The return walk is roughly seven kilometres; turn around earlier for a brief look. Use designated parking before the walk and do not stop for photos on the active highway bridge.

Key West and Sunset Logic

Start the full town day in Old Town with a section of Duval Street and side streets toward the Historic Seaport. Fort Zachary Taylor offers a separate beach and history block; check admission and daily opening.

The Mallory Square dock and plaza are the specific evening venue for Sunset Celebration. Expect other visitors, not a quiet private dock. An Old Town hotel can simplify walking; “Lower Keys” is not a synonym for a walkable Key West base.

Planning Logic

The return drive is its own travel day. Plan the next night in Homestead or Miami before a long-haul flight. An extra reef morning or boat trip must not consume the entire return margin.

Budget bands are per person for two adults sharing a room and car: one night, meals, shared rental and fuel. Flights, reef/boat tours, state-park admission and special hotel parking charges are additional. For example, a USD 300 final room rate means USD 150 per person before food, car and activities. Check hotel parking ahead; a cheaper room outside Key West may create daily return drives.

What I Would Prioritize

I would prioritize one water or nature stop, one middle Keys meal or marina pause, Seven Mile Bridge and a walkable Key West block. I would skip the forced end-to-end sprint.

Where to Go Next

Return to Miami, continue toward the Everglades via Homestead, or cross west toward Naples if the route is becoming a full Florida loop.
