  • North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
  • North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
  • North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
  • United States ↗Check whether you need an ESTA (Visa Waiver Program) or a visa on the official CBP and State Department sites; apply only through esta.cbp.dhs.gov, not third-party sites, and allow time before you book.
  • United States ↗Several popular national parks use timed-entry or vehicle reservations in peak season; check each park's page on nps.gov and book on recreation.gov before fixing your dates.
  • United States ↗Medical care is very expensive for visitors; buy travel insurance with high medical cover before you fly.
  • United States ↗Tipping is expected: about 15–20% at sit-down restaurants and bars, and a tip for taxis, hotel staff and guides.

Key Largo is the first island of the Florida Keys, about 1 h 15 min by car from Miami airport on US 1. It is a diving and snorkelling base rather than a beach town: the reef is offshore, the highway is the main street, and you need a car or a shuttle to move between mile markers. Two nights covers a reef trip, the state parks and one long dinner; one night works as a stop on the drive south.

Arrive & move

Airports are listed under At a glance; this is how to move once you are in

Getting around

A car is the practical choice: US 1 runs the length of the island and most businesses sit on it, with mile markers as the address system. There is a shared-use path beside the highway but it is a road-side ride, not a scenic one. Buses from Miami (Metrobus 301 and Greyhound/FlixBus) stop on US 1 but run a few times a day, so they suit arrivals, not daily sightseeing. Taxis and rideshare exist but are thin outside the centre.

Doable for a flight or a night out, but traffic on the return can double the time.

Walkable cluster of restaurants, dive shops and hotels around the Pennekamp park entrance; best for a first visit without a car every night.

Tavernier and MM 90–94

Quieter bay-side stays north of the centre; 10–15 min drive to the dive boats.

MM 95–99 (south Key Largo)

Resorts and marinas with their own docks; good for dive packages, less walkable.

Watch out

Safety

Key Largo is a low-crime resort island; the real risks are sun and water, fast traffic on US 1, and storms between June and November. Standard US precautions apply.
  • Hurricane season runs Jun–Nov; check forecasts and know your evacuation route north on US 1.
  • Sun and water: reef snorkel trips run 2–4 h with little shade, so cover up and reapply sunscreen.
  • The highway is the main street — cross only at lights and expect fast traffic.
  • Some dive and snorkel trips sell out in winter and on holiday weekends; book a day or two ahead.
  • Tolls on the Turnpike and the Homestead extension are electronic only; rental cars carry a transponder and the operator charges a daily fee.

Coming as the guide grows

  1. Airport-to-bed contract for MIA and FLL: last-mile drive times, toll setup and a late-arrival bed list.
  2. Four walking clusters with rescue anchors: Pennekamp entrance, MM 100–104, Tavernier and the bay-side resorts.
  3. Place pages with verified cutoffs (Pennekamp, Dagny Johnson Hammock, the African Queen) and eat pages with last orders.
  4. Storm and hostile-arrival fixtures so gates A–D can go green.
