Watching whales feels closer than you expect. This Royal Delfin 3-hour catamaran ride gives you 16 panoramic underwater windows plus a swim stop at Diego Hernandez Bay, and it usually comes with a guided-style explanation of what you are seeing. The biggest thing to watch for is space, because the boat can feel overcrowded, especially when wildlife pops up and everyone surges for the best angles.

I like that you are not just looking from the deck. You get a real second perspective from underwater viewing, and the onboard lunch and drinks make the whole morning feel like a full outing instead of a quick cruise. One more consideration, some sightings can be far off or you might see more dolphins than whales depending on the day, so keep expectations flexible.

Key points before you go

• Underwater viewing with 16 panoramic windows for sightings beneath the surface
• Diego Hernandez Bay swim stop in warm water, plus chances to cool off after spotting wildlife
• Lunch and drinks onboard including beer and sangria, plus soft drinks, juice, and water
• Purpose-built catamaran setup with restroom access and onboard areas for viewing
• Crowd management matters since deck congestion can block your view during peak moments

Royal Delfin catamaran and underwater windows, what you are really paying for

This tour works because the boat is designed for marine spotting, not just sightseeing. The headline feature is 16 panoramic underwater glass viewing windows, which means you can watch movement below without waiting for perfect surface timing.

That matters in Tenerife waters. Dolphins and whales do not stick around for long. With underwater viewing, you can still catch action even when animals surface briefly and then slip back down. In plain terms, it gives you more chances to see something, and it reduces the frustration of scanning the horizon for too long.

You also get an onboard feature described as Underwater Submarine Vision. Based on what people noted afterward, there is also a glass-bottom option if you want to go down and look. Translation: if you love the idea of seeing marine life from multiple angles, this is built for it.

One small but real mindset shift helps: the best views are not always where you are standing when you hear people cheer. You might have to move or reposition, and on busy days that can be hard. If you are the type who likes a calm, open deck photo session, plan for crowds at the moment wildlife is spotted.

The 3-hour plan from Puerto Colón to Diego Hernandez Bay

The day starts at 10:30 am at Av. de Colón, 11, Playa de la Américas (near Puerto Colón/Costa Adeje area). From there, you sail along the coast, moving from the Playa de Las Américas side toward Diego Hernandez beach.

The route is not about lots of stops. It is about staying out long enough for wildlife spotting and then building in a proper break with a swim. Expect the overall timing to feel like a steady morning rhythm: sail time, wildlife spotting periods, then the water stop and lunch.

The key highlight is the stop at Diego Hernandez Bay. That is where you swim in the warm water and where lunch is served onboard. This is not a rushed “jump in for five minutes” situation. It is a dedicated swim window, and it is part of why many people describe the trip as a great morning outing rather than a short snack cruise.

Do note the tradeoff. When the boat is busy, the swim area at the rear can get tight. One person reported being sandwiched in during the swim stop, with kids and adults packed into a small zone. That is exactly the kind of time when you will want your balance, patience, and a quick plan for where you will position yourself.

Wildlife spotting: whales and dolphins, and why sightings vary

This is Tenerife’s kind of ocean tour, you are heading out in search of whales and dolphins in their natural environment. The underwater windows make the spotting feel more personal, because you can see movement and passes below the surface.

People tended to love two things here:

• Lots of dolphins at once, especially when the water was clear and blue
• The sense that you were viewing animals from their environment, not from far away behind a barrier

Still, wildlife is wildlife. One comment said whales were seen far off and dolphins were not seen, which can happen on days when conditions are different. Another theme showed up around viewing distance: if everyone crowds the same side of the boat, your view of a distant animal can be blocked or blocked by motion.

So here is my practical advice: go with a flexible expectation. If your heart is set on whales close-up, you may leave with dolphins instead, or you might spot whales at a distance. If your main goal is to see dolphins and whales in underwater viewing conditions, you are far more likely to feel satisfied.

Lunch and drinks onboard, good value or a letdown depending on your taste

You do not come empty-handed. Lunch and drinks are included, and the list is specific:

• Beer and sangria (alcoholic beverages)
• Soda or pop, juice, and water
• A complimentary lunch
• A restroom onboard
• Swimming stop included at Diego Hernandez Bay

The interesting part is how people described the food. Some said lunch and drinks were very good, and they clearly enjoyed the meal as part of the whole experience. Others were blunt that the lunch quality was poor, comparing it to school dinners, with limited options.

That split matters for your decision. If you are the type who cares a lot about meal quality, you should mentally downgrade the lunch expectations and treat it as a convenience. You can still enjoy the day even if the food is not your favorite, because the underwater windows and swim stop are the real center of gravity here.

Also remember snacks are not included in the price, but you can buy them onboard for extra charge. Parking fees are also not included, so if you drive, factor that into your total spend.

The swim stop at Diego Hernandez Bay, fun water time with real crowd reality

The swim stop is one of the tour’s strongest selling points: warm water at Diego Hernandez Bay, plus the chance to cool off after time at sea. People described the swim as a key part of the overall experience, not just a token dip.

For families, there is an additional comfort detail: children receive life vests so they can swim in the sea. That is especially helpful if you are traveling with kids and you want them to enjoy the water without you constantly worrying about gear.

The main caution is space. During the swim stop, one review described being crowded into a small area at the rear of the boat, leading to minor injuries from bumps and contact. That does not mean it will happen to you, but it does mean you should keep your personal space in mind and be careful when boarding and when the group is funneling.

If you want the best odds of an easy swim experience:

• Aim to move calmly and avoid rushing to the exact rear edge at the first moment
• Keep an eye on kids’ arm flails and handholds, it gets chaotic fast
• If you do not love tight spaces, consider positioning where you can enter and exit without squeezing through bodies

Staff, guidance, and the “how” of the whale and dolphin experience

The most praised part of this tour is the people. Several comments highlighted friendly, attentive staff, from boarding to giving solid information about what whales and dolphins are doing.

That guidance tends to make a difference. When a dolphin is rolling, chasing, or surfacing, it is easy to miss the meaning of the behavior. A good explanation helps you know what you are seeing and when to look. The same is true for whales: you may only get brief surface moments, so knowing what signs to watch for makes your scans quicker and more rewarding.

There is also an added layer people seemed to enjoy: photo and video souvenirs. One person mentioned video and pictures available for purchase after the swim and viewing time. That is the kind of add-on many tours try, but here it seems to be tied to the activity rather than feeling random.

If you are someone who wants more than just watching, look for staff who will point out patterns during sightings. That is where you get the most value from the onboard commentary.

Price and value at around $60 per person, what feels fair

At $60.15 per person, this tour looks like decent value on paper because it includes more than a boat ride. You are getting:

• 3 hours on the water
• Underwater viewing windows
• Lunch and drinks (including beer and sangria)
• A swim stop at Diego Hernandez Bay
• Restroom onboard

But here is the honest balance. One review called it not worth their paid amount (they cited 105 euros) due to overselling and overcrowding. That complaint links to a real risk: if the boat is too full, you lose access to the best areas and you get blocked by people rushing for sightings.

So the value question comes down to your tolerance for crowd energy. If you accept that some wildlife moments can be chaotic on deck, you will likely feel the price is reasonable for a guided-style, meal-included dolphin and whale outing. If you strongly dislike congestion and you want wide open space, you might feel disappointed unless you luck into a lighter day.

You can also reduce the “surprise costs.” Parking is extra. Snacks are extra. Souvenir videos and photos are extra. Alcohol is included, but you should still budget if you plan to buy more snacks or souvenirs.

Should you book the Royal Delfin 3-hour Dolphin and Whale Watching with swim?

Book it if:

• You want underwater viewing as part of your marine spotting, not just surface watching
• You care about having lunch and drinks included so the trip feels like a full morning plan
• You are traveling with kids and like the idea of a swim stop with life vests available
• You can handle a lively boat atmosphere when wildlife is spotted

Consider skipping or comparing if:

• You hate crowded decks and worry about losing sightlines during peak moments
• You are extremely food-focused and are likely to be unhappy with meal quality variability
• You are only satisfied by close whale sightings, since marine conditions can change what you see

If you do book, I’d go in expecting a real marine adventure with real human crowd dynamics. When it all comes together, the combination of underwater windows plus a swim stop makes this feel like more than a basic tour.
