Those sea caves look close enough to touch. This East Coast Glass Bottom Boat Trip from Sa Coma is built for big Mediterranean scenery, with glass-bottom windows and time to swim in postcard coves. I like that it targets coves and caves along Mallorca’s east coast, not just one quick stop. The one thing to watch: when the sea gets rough, the route and swim time can shrink, and the ride may feel more like a transport run than a sightseeing cruise.

I also appreciate the straightforward setup: you meet at Sa Coma’s beachfront pier and go straight onto a catamaran with an onboard bar, bathrooms, and an expert local crew. Still, if you get motion sickness easily, come prepared, because some sail days can bring strong waves and cold wind that make staying comfortable a challenge.

Key points before you go

• Underwater windows plus slides: You’ll see the water below and still have fun at the back with two slides.
• Three different routes from the same pier: Choose an earlier Sea Odyssey, an afternoon Sea Odyssey, or the more cave-focused New Sea Paradise.
• Swimming stops matter more than long sightseeing: Most of the memorable moments are tied to the water time at each cove.
• Weather can change everything: The captain may adjust timing, swimming areas, and sometimes how long you’re actually out.
• No hotel pickup, food is extra: You’ll handle getting to the pier yourself, and you’ll want a plan for drinks and snacks.
• Not ideal for wheelchair users: The tour is listed as not suitable for wheelchair access.

Glass-Bottom Catamarans: Seeing Mallorca Underwater (and Above)

This trip is simple in the best way: you’re on the water, and the boat is designed for visual fun. The catamarans have underwater viewing windows, so you can look down during the ride, not just during swim stops. At the back there are two slides, which turns a swim into something more like a short water park moment.

On board you’ll also find bathrooms and a bar service. That matters, because even on a smooth day, Mallorca’s sun + salt air can make you want easy comfort without scrambling for shoreline options.

The comfort reality

You may hear this described as a “boat trip through coves,” but the feel depends on sea conditions. On calmer days, it’s relaxing and scenic. On rough days, the same catamarans can feel like bouncing from point to point. The boats are meant to be safe and comfortable, but the water decides how “comfy” it feels.

If you’re sensitive to motion, I’d take it seriously: plan for wind chill, bring a layer, and consider motion-sickness support. Cold wind shows up fast on the east coast.

Pick Your Route: Sea Odyssey vs New Sea Paradise

There are three options, all starting from Sa Coma. The main difference is how much of the day goes toward the east-coast variety and how cave-heavy the route feels.

Sea Odyssey (3.5 hours) from 10:00

This is the morning choice. You leave at 10:00 am and return to Sa Coma around 1:30 pm after about 3 hours 30 minutes on the water.

The stop sequence is built around classic east-coast anchors and then moves into more dramatic stretches. You’ll pass by places like Cala Morlanda, then Porto Cristo, and the area beaches around Cala Millor and Cala Bona. After that, the route continues toward Cala Ratjada and Font de Sa Cala, then reaches Cap Vermell and the Coves d’Artà before ending in Canyamel. There’s a swim stop in crystal-clear water at the end.

If you like the idea of a full morning outside and a late lunch back on land, this option usually fits best.

Sea Odyssey (3 hours) from 1:30

If you’d rather not be thinking about sunscreen at 10:00, go afternoon. The boat departs at 1:30 pm and ends back in Sa Coma around 4:30 pm.

This route follows a similar east-coast spine—Cala Millor, Cala Bona, then toward Cala Ratjada and Font de Sa Cala, plus Cap Vermell and Coves d’Artà—then finishes with a swim stop at Canyamel.

This one is for people who want a sea break after lunch, without committing to the longer morning window.

New Sea Paradise (3 hours) from 11:45

This is the more nature- and cave-focused pick. You depart at 11:45 am for about 3 hours, returning at 3:00 pm.

You start with Cala Morlanda and a swim. Then you head toward Porto Cristo and the coves around Cala Magrana, Cala Mendia, Cala Anguila, and Cala Romántica. As the route continues, the story turns more “explorer”: you head into the area near the Pirate’s Cave and other sea caves shaped by time and waves.

You’ll also get a second swim stop connected to Cala Varques and its natural bridge, which is the kind of scenery you really want to see from the water. The final portion includes additional hidden coves such as Cala Virgili, Cala Pilota, and Cala Magraner.

If your top priority is cave drama and swim settings that look like they belong on a movie set, this option is the best match.

Where the Boat Stops: What Each Area Is Good For

Trying to choose between routes is easier when you understand what each stop type gives you. Here’s how the itinerary’s geography tends to play out for your day.

Cala Morlanda: the first “I get it now” swim

Cala Morlanda shows up in all options, which makes it a key baseline for the experience. It’s the early chance to get into clear water and reset your day after the pier.

Even if your eventual highlight is a cave, the first swim stop is often what makes the trip feel worth it quickly. It’s also a good moment for families: dip, cool off, repeat.

Porto Cristo and nearby coasts: the transition zones

Porto Cristo appears on the routes like a hub, a visual and geographic midpoint. You’re not going there for a long land visit—you’re passing it by while getting more of the coastline views.

For people who like the “sea cruising” part as much as the water time, these transition stretches are what keep the ride interesting.

Cala Millor, Cala Bona, and the east-coast rhythm

The routes include Cala Millor and Cala Bona, which means you’ll see the more populated side of the coast from a distance. That’s not a downside by default. It helps you get a sense of the region’s layout and where the scenic pockets begin.

Then, the boat angles toward more rugged segments like Cala Ratjada and Font de Sa Cala, where the visual character changes and the coastline starts looking more like natural sculpture.

Cap Vermell, Coves d’Artà, and Canyamel: the big-rock finale

Cap Vermell and the Coves d’Artà are the dramatic rock and cave territory. If the sea is running smoothly, these areas are where your brain goes quiet because the shapes are so clear from the water.

Most versions finish with a swim stop near Canyamel. That’s often where you want to be at your best—dry clothes ready, a towel on your plan, and a willingness to spend a little time in the sun after you climb back aboard.

Swimming Stops and Sea Caves: The Best Part, With One Catch

The tour is built around swim time, and it delivers on the visual part. But you should know how swim time can work in real conditions.

The captain can adjust the route and the swimming area based on weather. When conditions are rough, you may see shorter swim windows or less time around certain spots. Some people have described swim time becoming quite limited on choppier days—think quick dips rather than a long float-and-chill.

Cave moments can be spectacular, but they also come with constraints. If you’re hoping for slow exploration, remember you must stay on the boat during excursions. Swimming and staying close to the boat are part of the rhythm.

A practical tip: pack for cold wind after water

Even in warm months, cold wind can hit right after you climb out. If you want to stay happy, bring a light layer you can pull on quickly. This matters for both comfort and keeping the day fun, especially if sea conditions make everyone a little less cheerful.

Underwater windows: when viewing depends on the seat

The glass-bottom windows are a signature feature. On rough days, the boat can move more than you expect, and your position on the boat can affect what you see. If the water gets bouncy, plan to watch from a stable spot rather than grabbing the best view at the cost of comfort.

Motion, Choppy Water, and Diesel Smell: How to Avoid Regrets

This is where the balanced advice comes in.

If you’re prone to motion sickness

The ride can be anything from calm to uncomfortable depending on the day. When seas get rough, you might feel it more strongly on a fast-moving catamaran. I’d treat this as a “plan ahead” activity if you or someone in your group gets sick easily.

Bring what helps you—whether that’s medication you trust or strategies like sitting toward the middle and keeping your gaze on the horizon. Cold wind adds to discomfort, so layering is not overkill.

Watch your comfort around the underwater windows

Some people have noted a bad odor from engine exhaust around the glass areas at certain times. I can’t promise it will happen on your day, but it’s a useful heads-up: if odor bothers you, don’t plan on spending the entire ride pressed to the underwater windows. Mix it up—watch the coastline, then take your underwater looks in short bursts.

Value for $37: What You Get, What You Pay for Separately

At around $37 per person, this is priced like a value experience—especially because it combines a ride, underwater viewing, and actual swim stops. You’re paying for access to water-based scenery that’s hard to replicate by land.

But “good value” doesn’t mean “nothing to think about.” Here’s what you should factor in:

• Food and drinks are not included.
• There is a bar service onboard, but you’ll likely buy drinks there.
• Hotel pickup is not included, so you’ll need to be at the pier yourself.

So the best value comes when you travel light and plan for basics: water, a small snack if you need it, and a change of clothes or at least a towel.

If you’re comparing this against other Mallorca boat outings, the decision usually comes down to whether you want glass-bottom viewing and slides plus cave-heavy scenery. If yes, this price band is easy to justify.

Getting There at Sa Coma: The Pier Location That Matters

This trip’s meeting point is at the pier at the beginning of Sa Coma beach, on Carrer Atzeroles, and also at the end of Passeig Neptú. Arrive about 10 minutes early so you’re not rushing onto a boat that’s already ready to load.

There’s no hotel pickup, so build that into your plan. If you’re staying outside walking distance, factor in local transport or a taxi timing buffer.

Also note: you must stay on the boat at all times during the excursions, except if a transfer is included in the itinerary. Practically, that means your main “off-boat” time is the designated swim stops.

Who Should Book This (and Who Should Skip It)

This is a great match if:

• You want a water-focused Mallorca experience rather than a long bus-based day.
• Your group includes kids, because slides and swim time make it feel playful.
• You care about underwater viewing and like the idea of checking out the water below while cruising.

You might rethink it if:

• Someone in your group is wheelchair dependent. The tour is listed as not suitable for wheelchair users.
• Your group is very sensitive to motion sickness and rough water. The captain’s route adjustments and variable sea conditions can change the comfort level fast.

Should You Book the East Coast Glass Bottom Boat Trip?

I think this is worth booking if you’re realistic about what a boat day can be. The cave scenery, coves, and swim stops are the point, and the glass-bottom windows plus slides make it more fun than a plain sightseeing cruise.

Book it with confidence if:

• You want an easy, self-sourced day from Sa Coma.
• You’re okay handling drinks/snacks separately.
• You can handle some wind and movement and you’ll dress for it.

Consider a different plan if:

• You know you get seasick easily and can’t manage it.
• Your group needs lots of land time or long stops away from the boat (this isn’t built for that).

If you’re choosing between routes, go New Sea Paradise for cave intensity, and go Sea Odyssey if you want a more straightforward east-coast loop with a simple, classic swim finale.
