What you'll see and do
Florida Keys
From our sun deck, you will have a panoramic offshore view of the Florida Keys and can view the ever-changing colors of the Atlantic Ocean. Once we reach the reef, you will be able to observe the coral reef through our large viewing windows, which are large enough for everyone to observe the reef at the same time and are located along the center of the boat and installed flat so there is no distortion other than what nature creates. Everything you see on our tour is or was alive and the reef itself is built off of many varieties of living coral and teems with an assortment of sea life. Your tour guide will be able to point out all kinds of sea creatures which may include sea fans, sea plumes and hundreds of fish ranging from small tropical to larger species sought after by local fishermen.

Great Tour
If you are looking for a great experience in the Florida Keys, I highly recommend this. The guide's knowledge was exceptional and highly interactive.

Excellent experience!
The guide was incredibly friendly and knowledgeable about the reef. The vessel itself was clean and easy to get around, both topside and in the main viewing area. This was a definite highlight of my first trip to the Keys.
Response from the operator: Thank you for the incredibly rating and review, so glad we were part of your first experience to the Keys!

Easy to find. Beautiful...
Easy to find. Beautiful views. Knowledgeable staff. Helped passengers when they started to feel motion sickness.
Response from the operator: Jennifer, glad you could find beauty during our voyage!
via Viator
There was unfortunately...
There was unfortunately very little to see in the reef. The boat is uncomfortable with almost no seating up top where the drinks are.
Response from the operator: Donald, sorry if we failed to meet your expectations, thank you for taking the time to review your voyage with us.

Why this scores 64
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Key Largo Coral Reef Glass Bottom Boat Adventure: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Key Largo.
How much does Key Largo Coral Reef Glass Bottom Boat Adventure cost?
+
Prices start at $67 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Key Largo usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Key Largo Coral Reef Glass Bottom Boat Adventure take?
+
Plan for about 2 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Key Largo is not rushed.
Is Key Largo Coral Reef Glass Bottom Boat Adventure worth it?
+
It holds an Outty Ranking of 64 out of 100, which we label "Solid Choice". That score blends traveler sentiment (4.1/5 across 1,218 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable most popular in Key Largo, and how flexible the cancellation terms are.
Can I cancel or reschedule Key Largo Coral Reef Glass Bottom Boat Adventure?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Key Largo Coral Reef Glass Bottom Boat Adventure suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 2-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Key Largo Coral Reef Glass Bottom Boat Adventure?
+
Around 426 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Key Largo can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Key Largo and add a light layer if any part of the 2-hour experience runs outdoors or after sunset.
Where does Key Largo Coral Reef Glass Bottom Boat Adventure start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Key Largo within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Key Largo?
+
Key Largo is the dive and snorkel capital of the Keys: John Pennekamp reef trips, Christ of the Abyss snorkels, glass-bottom boats, sunset sails and backcountry eco tours. On Outty we rank every Key Largo experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Key Largo Two Reef Snorkel Tour - All Snorkel Equipment Included!, Half Day Snorkel Trip on Reefs in the Florida Keys, Mangrove Tunnel Kayak Adventure in Key Largo. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Key Largo?
+
December to May for clear water and calm seas. Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Key Largo?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
