Dolphins and Snorkeling from Key West: Which Boat, Which Time of Day

The single most booked activity in Key West is a dolphin trip with snorkeling attached. Our inventory holds 12 dolphin-watching offers with 1,805 reviews between them, and the most reviewed of them all – the Dolphin Watching and Snorkeling Eco Cruise, 867 reviews at 4.6 stars – is also the most reviewed activity on the whole island.

Before you compare prices, understand one thing, because it is what people get wrong and then complain about in the reviews.

The snorkeling on a dolphin trip is not reef snorkeling

Dolphins in Key West live in the shallow backcountry on the Gulf side, not out at the barrier reef. So a dolphin boat runs north into flats and channels, and when it stops for snorkeling, it stops there. The Eco Cruise describes exactly that: cruise “to the backcountry waters for some snorkeling fun of your own”. The sunset version snorkels inside the Key West National Wildlife Refuge.

Backcountry water is shallow, warm and often a little cloudy, with seagrass, sponges, small rays and juvenile fish. It is a good snorkel. It is not the coral reef with parrotfish and brain coral that the postcards show – that is a different boat going in the opposite direction, and it is covered in our guide to reef snorkeling.

If you want both on one day you will be on the water for a long time. If you have one morning only, decide which of the two you actually came for.

Morning or sunset

The same operator sells both, and they are genuinely different trips.

The morning and midday trips give you clearer light in the water and usually calmer conditions. The Eco Cruise runs 3 hours at €64.27 and includes snorkel gear, guide, water, soda and beer, wine or Champagne after the snorkel – towels, here too, are explicitly not on the list.

The sunset trip runs the same 3 hours at €70.19, watches dolphins first and sails home into the sunset with a cold beer. What you give up is underwater light: you snorkel late in the day. What you gain is that you do not have to book a separate sunset sail – one boat does both. It carries 571 reviews at 4.4 stars, marginally below the morning boat.

A third shape exists: the afternoon catamaran sail with dolphin watch, 2 hours 30 minutes on a 60-foot catamaran at €52.63. It is the cheapest dolphin trip in the inventory and the honest reason is that there is no snorkeling in it. If you have a non-swimmer in the group, that is a feature, not a shortcoming.

Big catamaran or six people

This is the real fork, and it costs money.

The big boats carry a lot of guests, include an open bar, and cost between €52 and €70. The small boats charge roughly double. The small-group dolphin and snorkel tour takes a maximum of six guests, costs €112.30, rates 4.7 stars, and throws in free parking – which matters more in Key West than it sounds. The Honest Eco trip runs 4 hours at €125.59 on what the operator calls the quietest boat in the Keys and advertises a resident population of over 200 wild bottlenose dolphins. It has three reviews. Three reviews is not a warning and it is not a recommendation – read them.

The longest option, the five-hour trip to a secluded sandbar and the dolphin playground with lunch and unlimited drinks, is €131.64 and combines this with a sandbar afternoon.

One seasonal note worth checking before you book anything with sails: one of the sailing dolphin trips states plainly that it sails “in the Winter months”. Rig and season are not the same thing here, and the calendar on the booking page is the only reliable answer.

How close the boat is allowed to get

This is the part no operator puts in the headline. NOAA Fisheries asks people to stay at least 50 yards away from wild dolphins – about half a football field – and feeding or harassing wild dolphins is illegal under the Marine Mammal Protection Act.

That number tells you what a dolphin trip actually is. It is not a swim-with-dolphins experience, and no boat here sells one. You watch animals that are going about their day at a distance, from a deck, sometimes for a long time and sometimes briefly. Bring a camera with reach, or accept that the photographs will be mostly water.

Nobody guarantees sightings. The Eco Cruise says so on its own booking page, and so do we.

Who should not book this

The Eco Cruise lists itself as not suitable for wheelchair users and not suitable for non-swimmers. The sunset trip lists itself as not suitable for people with mobility impairments. Those are the operators’ own words on their own booking pages, and they are the ones that count – ours would be a guess.

If you are travelling with children: on the Eco Cruise, guests aged 14 and under must have an 18-plus chaperone with them throughout the tour. That is a supervision rule, not a minimum age – the difference matters, and it is the kind of thing that gets misread into “children not allowed”. Alcohol is served to guests 21 and over with photo ID. More on family fit in our Key West with children guide.

None of these boats picks you up at your hotel – the sunset trip and the five-hour sandbar trip rule it out explicitly. Meeting points are scattered along the Historic Seaport – 631 Greene Street for the Eco Cruise, 201 William Street for the sunset trip. Walk it once the day before if you are on a tight morning.

What it costs

Dolphin trips start at €52.63 and the median in this category is €107.59 – higher than the median for boat tours generally, which is €99.70, and well above the €78.97 median for sunset trips. Prices show in euros here because GetYourGuide converts them; the operators charge in US dollars, so the figure on the booking page can differ slightly by the day.

Gratuity is not included on either of the big boats, and the Eco Cruise applies an automatic 10 per cent service fee to parties of eight or more. Budget for it rather than being surprised at the dock.
