Key West Glass-Bottom Boat Tour: What to Expect

Fury Water Adventures’ glass-bottom boat is the way to see the Key West reef without getting wet: about an hour and three quarters on a 65-foot catamaran with viewing windows in the hull, from $64 per person on Viator and GetYourGuide (checked November 2026). It also has the lowest rating of any trip we review on this site: 3.9 from 618 reviews on Viator’s listing, and 4.2 from 124 on the same trip on GetYourGuide. Book it if you can’t swim, have small children or simply don’t want to get in. If you can float in a vest, a shallow-water snorkel trip gives you more for the money. Our glass-bottom boat review →

What the trip includes

The Viator listing describes glass “windows to the reef” running along the hull, an air-conditioned viewing cabin, a large sundeck, a restroom, and guides who talk through the reef ecosystem and point out marine life. Daytime trips run about 1 hour 45 minutes. The last trip of the day returns at sunset with a glass of champagne, and in some seasons runs a little over two hours.

On Saturday 14 November, Viator’s schedule showed departures at 12:00, 14:00 and 16:00, priced at $64 and $80 depending on the sailing. You check in 30 minutes before departure at the large Glass Bottom Boat booth between the Ocean Key Hotel and the Pier House. The listing marks the boat as wheelchair accessible, and in poor conditions the captain may choose an alternate location to the reef.

Not included: snacks and soft drinks (the GetYourGuide listing mentions a cash snack bar at $2 an item, and water is included there), parking, which Fury does not provide, and gratuity. Groups of eight or more pay an automatic 10% gratuity at check-in. Anyone 17 or under needs an adult with ID at check-in to sign the waiver, and children 14 and under must have an adult with them on the trip.

Why it rates lower than the snorkel trips

The snorkel trips we review mostly rate 4.4 to 4.9. The glass-bottom boat sits at 3.9 on Viator, and the reasons show up clearly in its lower-star GetYourGuide reviews.

• Fewer fish than people hoped. The most common complaint is a thin view: not much variety through the glass, and children who were expecting turtles and rays went home without them.
• Murky water on some days. When the sea is stirred up, the view through the glass can be cloudy, and one reviewer could not follow what the guide was pointing out.
• A rolling boat. When the catamaran stops over the reef, it moves with the swell, and several reviewers felt seasick or found it hard with small children.
• A lot of ride for one view. Much of the trip is the run out and back, with one stop over the reef, and a few reviewers found it dull.

The better reviews, including the Viator ones shown further down this page, praise informative, friendly guides, the boat ride itself, room on deck and the sunset sailing with champagne. Several Viator reviewers liked that it is a quiet, family trip with no party atmosphere.

Snorkelers face the same weather and visibility, but they are in the water, closer to the fish. Marine life is never guaranteed on any trip.

If you are prone to seasickness, the CDC’s advice applies: avoid the parts of the boat that move most, such as the bow, keep a view of the horizon, avoid reading or screens, limit alcohol, and take any medication before symptoms start.

Who the glass-bottom boat suits

The trip makes most sense for people who would otherwise stay ashore: non-swimmers, travelers with limited mobility (the listing marks it wheelchair accessible), grandparents traveling with grandchildren, and anyone who wants an hour or two on the water with air conditioning and a guide. The sunset sailing adds a glass of champagne and the evening light for the trip back.

It suits strong swimmers less well. For $15 less, Fury’s morning reef snorkel puts you in the water over the reef, and its lower-rated reviews are about crowds and conditions, not about seeing little. If you get seasick easily, the rolling stop over the reef is the part to think about; a sandbar day in shallow water may be gentler, though no listing promises calm seas.

Viator or GetYourGuide?

It is the same Fury trip on both networks at the same $64 starting price. GetYourGuide’s listing rates higher (4.2 from 124) and lists water as included; Viator’s has five times the reviews (3.9 from 618) and shows the full schedule. Pick the one whose calendar shows the departure you want.

Can you do glass-bottom and snorkeling on one trip?

Not on this boat: Fury’s glass-bottom trip has no snorkeling, and no listing in our data combines the two. If your group is split between swimmers and non-swimmers, Fury’s FAQ points non-swimmers to the glass-bottom boat and requires anyone snorkeling to know how to swim, so the usual answer is two separate tickets. Plan the meeting points too: the reef snorkel checks in at the Fury booth on the pier behind Opal Key Resort, 241 Front Street, while the glass-bottom boat uses its own booth between the Ocean Key Hotel and the Pier House. If you book both on the same day, leave time to walk between them and to check in 30 minutes ahead at each. Fury’s reef snorkel starts at $49 for the swimmers; see our cheap snorkeling page.

Other options if you can’t swim

Swimming rules are set by each operator, not by law, so read the listing and ask before you book.

• A shallow-water snorkel. Dolphin Echo’s shallow-water snorkeling and dolphin watching trip is $109 for four hours on a sailing catamaran limited to 14 passengers, with a shallow snorkel stop at a reef, wreck or the wildlife refuge, whichever has the best conditions. It rates 4.6 from 476 on Viator. It is not for children under five and has no free cancellation (the operator applies its own two-week policy). The listing does not say whether vests are provided, so ask. NOAA recommends a snorkel vest over a pool noodle for beginners, and floating on your back to rest, never standing on coral.

• A sandbar day. Fury’s Island Adventure ($110) and Sunset Watersports’ sandbar and kayak tour ($161) stop in shallow water you can wade in, when the tide allows, with floats and lily pads. Both list themselves as suitable for all fitness levels. See our snorkeling and sandbar page.
• Wildlife from the boat. Key West Extreme Adventures’ shark and wildlife viewing trip is $99 for two hours, and guests stay on board while bait draws sharks to the side of the catamaran. It rates 5.0 from 3,414 on Viator.
• Snuba, with care. Snuba of Key West ($160, 4.8 from 517) lets you breathe underwater from scuba equipment without a dive certificate. The listing does not say whether non-swimmers can take part, requires a medical waiver with medical exclusions, and is not recommended for travelers with spinal injuries, poor cardiovascular health or who are pregnant. Fuel and fees are extra and there is no free cancellation. Call the operator before booking for a non-swimmer. Our Snuba review
