Key Takeaways
FAQs About a Key Largo Vacation
Is Key Largo a good place to vacation?
Yes, Key Largo is a great vacation spot if you want a relaxed Florida Keys trip focused on snorkeling, boating, sunsets, and nature. It’s especially good for travelers who like being on the water more than shopping districts or nightlife.
Is Key Largo worth visiting?
Yes. Key Largo is worth visiting for reef access, easy boat tours, mangrove scenery, and the “gateway to the Keys” vibe. It’s one of the easiest places to get a true Keys experience without driving all the way to Key West.
Is Key Largo better than Key West?
It depends on your travel style. Key Largo is better for a quieter pace, snorkeling/diving, and resort-style relaxing. Key West is better for nightlife, walkability, and a busy historic town atmosphere.
How many days should I stay in Key Largo?
Most visitors enjoy 3–4 nights for a first trip. Two nights works for a quick getaway, while 5+ nights is great if you want multiple water activities and lots of downtime.
What is Key Largo known for?
Key Largo is known for John Pennekamp Coral Reef State Park, reef tours, snorkeling and diving, and classic Florida Keys scenery like mangroves, canals, and sunset views.
Does Key Largo have good beaches?
Key Largo has small beach areas and waterfront parks, but it’s not known for long, wide sandy beaches. The Keys are more about water access, boating, and reef activities than traditional beach towns. We like the beaches at John Pennekamp State Park. Although they are small, you can easily combine the beach with snorkeling nearby. Many resorts in Key Largo and the Florida Keys have beautiful private beaches.
Is Key Largo good for families?
Yes—Key Largo can be very family-friendly, especially for families who like boat rides, wildlife, and easy outdoor activities. Resorts with pools and on-site activities make family trips much easier. We recommend reading all of Key Largo FAQs and see if any other destination can compare.
Do I need a car in Key Largo?
Usually, yes. Key Largo is spread out along US-1 and isn’t very walkable overall, so a car helps you reach tours, parks, and restaurants without hassle.

Most families do. Key Largo is spread out along US-1, and driving makes it easier to reach parks, tours, and restaurants.

FAQS About Why Key Largo is Famous
Is Key Largo more famous than Islamorada or Marathon?
Key Largo is often the best-known name, mostly because of diving fame and pop-culture recognition—but each island has its own vibe.

The reef access—especially John Pennekamp Park and the sanctuary dive/snorkel sites.

Yes. You can do glass-bottom boats, wildlife tours, the African Queen cruise, and hammock hikes and still have a very “Keys” trip.
FAQs About What to do in Key Largo for a Day
What are the best things to do in Key Largo in one day?
The best one-day plan is a morning reef experience (snorkel or glass-bottom boat), a short nature stop (hammock trails or a wildlife center), and a sunset finish with dinner or a sunset cruise.
What is the number one attraction in Key Largo?
John Pennekamp Coral Reef State Park is the top Key Largo attraction because it offers reef tours, snorkeling, glass-bottom boats, and easy access to the Keys’ signature underwater scenery.

Plan 2–4 hours if you’re doing a boat tour or snorkeling. If you’re only stopping for a quick visit and a short walk, 60–90 minutes can work.

Switch to land-based stops like Dagny Johnson Key Largo Hammock Botanical State Park, the Florida Keys Wild Bird Center, the African Queen canal cruise, and souvenir stops along US-1.

Yes. You can still enjoy boat cruises, mangrove and hammock nature walks, wildlife viewing, and great food and sunset spots without getting in the water.

Morning is usually best because winds are often lighter and the water can be calmer, which improves visibility and makes boat trips more comfortable.
What’s the best way to end a one-day Key Largo itinerary?
Plan a sunset view on the bayside or take a sunset cruise, then finish with an easy seafood dinner—sunset is one of the simplest “can’t-miss” highlights in Key Largo.
FAQs About the Island of Key Largo
How many miles long is Key Largo?
Key Largo is approximately 15 miles long as traveled on the Overseas Highway and it is the largest island in the Florida Keys. Overall, including north Key Largo, the island is 33 miles long. Most people only see the part that stretches from the northernmost part of the Keys near the Overseas Highway’s Mile Marker 106 down to about Mile Marker 91. It is the longest island in the chain, offering plenty of space for outdoor activities, resorts, and nature preserves.
What is the population of Key Largo?
Key Largo (the Key Largo CDP) had 12,447 residents in the 2020 U.S. Census. We would add that the population swells during peak seasons from January through March with temporary winter residents.
Can you walk around Key Largo?
Key Largo is not like Key West with one mile long street where all the activities take place. The town (and island) is on both sides of the road near the waterfront. It runs for miles as the largest island in the Keys.
What is so special about Key Largo?
Key Largo is special because it serves as the gateway to the Florida Keys, offering an incredible mix of natural beauty, world-class diving, and eco-adventures. Whether you’re into fishing, snorkeling, or just relaxing on the water, Key Largo combines adventure with laid-back island vibes, making it a top destination for nature lovers and outdoor enthusiasts.
Key Largo FAQS About Mile Markers
What are mile markers in the Florida Keys?
Florida Keys mile markers are the green-and-white signs along US-1 (Overseas Highway) that help you pinpoint locations across the islands—especially because many physical street addresses can be hard to spot or may be missing after storms. They’re one of the easiest ways to navigate, since locals and businesses often give directions by mile marker.
Where do the mile markers in the Florida Keys start?
For travelers, the mile markers “start” at Mile Marker 0 in Key West and increase as you head northeast. In this Florida Travel Blog guide, the list begins at MM 126.5 near the US-1/Card Sound Road junction as you enter the Keys area.
Do mile markers go up or down when driving toward Key West?
They count down as you drive south toward Key West. If your mile marker numbers are getting smaller, you’re heading closer to MM 0.
Why do some locations have decimals like MM 66.2?
The physical roadside signs are whole numbers, but guides often use decimals to show a spot that’s part of a mile before/after a marker (example: “66.2” means about 0.2 miles past MM 66). Florida Travel Blog notes these are their calculations—you won’t likely see tenths on the actual signs.
How do I use mile markers to find a restaurant or attraction?
If a place is listed at a mile marker, you can drive to that marker and then look just before/after it based on the decimal (if given). Florida Travel Blog’s guide explains that a spot at 66.2 is 0.2 miles from the MM 66 sign (and also 0.8 miles from MM 67).
What does “oceanside” vs “bayside (gulfside)” mean with mile markers?
“Oceanside” and “bayside/gulfside” tell you which side of US-1 the location is on. This post also notes that, when an address is visible, odd numbers are typically on the ocean side and even numbers on the Florida Bay side.
How can I calculate the distance between two stops using mile markers?
You can estimate distance by subtracting mile marker numbers. An example is that if the Seven Mile Bridge begins at MM 40, that’s roughly 40 miles from MM 0 in Key West.
What is the famous mile marker in Key West?
The most famous mile marker is Mile Marker 0 in Key West, where thousands of visitors take photos. Florida Travel Blog notes it as the southernmost mile marker in the U.S. and a classic “you made it” moment.
What mile marker is Key Largo?
Key Largo begins around the MM 106–107 area (this guide labels it “Key Largo Mile Marker 106” and lists Key Largo landmarks starting at about 106).
What mile marker is Islamorada?
This guide shows Islamorada beginning around MM 91 (near Tavernier Creek Bridge) and then lists many Islamorada stops through the 80s.
What mile marker is the Seven Mile Bridge?
Florida Travel Blog explains the Seven Mile Bridge spans from about MM 40 (on the west end) to MM 47 (on the east end)), which is why it lines up with being about seven miles long.
Do mile marker locations change over time?
Yes—businesses can close or rename, and even bridges can be replaced (fixed vs drawbridge changes). That’s why Florida Travel Blog updates their mile marker list and provide a downloadable version.
FAQs About Manatees in Key Largo
Are manatees common in Key Largo?
They’re present in the Keys, but in Key Largo, you’re more likely to see them occasionally rather than in massive daily congregations.
What months are best to see manatees in the Keys?
Winter months are best, especially during cooler weather patterns when they seek warmer water.
What’s the #1 rule when you see a manatee?
Look, don’t touch—and don’t chase or crowd them.
Key Largo FAQS About Spearfishing
Is spearfishing allowed anywhere in Key Largo?
In state waters around Key Largo, spearfishing is prohibited because Key Largo is in the Upper Keys no-spearing zone.
Can I bring a speargun on my boat in Key Largo waters?
Certain sanctuary zones restrict carrying/possessing spearguns except while passing through without interruption, and NOAA lists additional possession restrictions in specific zones.
Does “Pennekamp” have its own spearfishing rule?
Yes. Florida Statute 379.2425 explicitly prohibits spearfishing within John Pennekamp Coral Reef State Park.
