Key West sits about 160 miles south of Miami at the far end of the Overseas Highway, and a coach day trip is the lowest-effort way to see it if you do not have the days to spare for a proper Keys road trip. The drive itself is half the story: the road hops island to island across more than forty bridges, with Florida Bay on one side and the Atlantic on the other, and the Seven Mile Bridge is the stretch everyone photographs through the window. You arrive with a few hours on the ground, enough for the essentials: a walk down Duval Street, the red-black-and-yellow Southernmost Point buoy, the Hemingway Home and its polydactyl cats, the harbor at Mallory Square, and a slice of Key lime pie from whichever shop you decide is the right one. The honest trade-off is time. Most operators leave early and return late, so a large share of the day is spent on the road, and the stops on the way down vary by company. Treat it as a sampler, not a deep visit, and pick it if you want to say you have been rather than if you want to linger.
The route runs south from the Miami area through Florida City and onto the Overseas Highway, built over the old Flagler railway line. Between Key Largo and Key West the scenery is mostly water and mangrove, punctuated by roadside fish shacks, marinas and the occasional rest stop that coaches use for a comfort break.
Sit on the water side going down if you can, since the view from the Seven Mile Bridge is wider and the light is usually better in the morning. Keep a jacket handy for air-conditioned coaches, and carry a charged phone and a water bottle, because the road has few places to stop on your own schedule.
Once in Key West, the island is small enough to cover on foot, which is what makes a short visit workable. Duval Street runs from the Gulf side to the Atlantic and is the center of the bar and shop scene, but the quieter side streets hold the better-looking old conch houses and gingerbread porches. The Southernmost Point marker draws a queue, so decide early whether the photograph is worth the wait.
Mallory Square and the waterfront are the traditional gathering place near sunset, but most day trips leave before that, so ask your operator about the departure time and whether any optional add-ons such as a snorkel or boat outing are bundled in. Some itineraries include those, and some are walking-and-free-time only.
Practical planning matters more than on most excursions. Confirm the pickup point, the return time and what is included before you book, because this product category varies widely between operators. Bring cash for tips and small purchases, sunscreen, comfortable shoes, and a light snack for the ride. If you are traveling with young children, remember that the total day can be very long and bus time is the hard part.
If you can afford two nights, a self-driven or overnight option usually gives a better Key West than a day trip does, but for visitors working from a Miami base with limited days, a single day still delivers the bridges, the island atmosphere and a taste of the Keys.
What to expect
The experience
A long coach day trip down the Overseas Highway with a few hours of free time in Key West, sometimes with optional boat or snorkel add-ons depending on the operator.
Best time
Winter and spring are the most comfortable; summer is hot and can bring afternoon storms. Check the departure time to understand how much daylight you will have on the island.
How long
Plan for a full day of roughly twelve to fourteen hours door to door.
Tips
Sit on the water side going south, bring a jacket for the air conditioning, confirm included stops and the return time, and decide your Key West priorities before arriving so you are not choosing while the clock runs.
Quick picks

Good questions
How far is Key West from Miami?+
Roughly 160 miles, usually three to four hours each way by road depending on traffic and stops. That driving time is why the day is long and why operators leave early.
Is a day trip enough for Key West?+
It covers the highlights: Duval Street, the Southernmost Point, the waterfront and a meal. It will not give you sunsets, the reef or the quieter parts of the island, which need an overnight stay.
Are snorkeling or boat trips included?+
That depends on the operator and the option you pick. Some itineraries are walking and free time only, others bundle a boat or snorkel outing, so check the inclusions before you choose.
When is the best time to go?+
Winter and spring have the mildest weather. Summer is hotter and storm-prone, though the drive is still scenic and fares and crowds can be lighter.
What should I bring?+
Sunscreen, a hat, comfortable walking shoes, a light jacket for the coach, water, snacks and some cash. Your phone camera will get a workout on the bridges.
