Secret bays are easier than you think.

A small-boat trip out of Sesimbra is a simple way to see the rugged coast of the Setúbal region, with short stops at quiet beaches and time in the water with provided snorkeling gear. The pace is relaxed, the group is small (max 8), and the guides keep things clear in English as you move from one cove to the next.

Two things I really like: first, the trip feels hands-on because you actually get water time at multiple beaches instead of just watching the shore. Second, the crew energy matters—Marco and Jorge are friendly and explain what you’re seeing while keeping everyone comfortable on the water. One possible drawback: the water can run cold, so plan for chilly snorkeling days (a wet suit can help).

Key highlights I’d plan around

• Max 8 people, so you’re not stuck in a huge crowd during short beach stops
• Snorkeling kit and safe included, which removes a lot of hassle
• Four beach stops with set time blocks for swim time and views
• English-speaking guides who keep the trip moving and understandable
• Regional drink included, with reports of wine at the end

Why this small-boat trip from Sesimbra feels worth it

This experience is built for people who want the coast without the stress of figuring it out point by point. You’re out on a boat for about 2 hours 30 minutes, and because the group is capped at 8 travelers, you tend to get a more personal rhythm: less waiting around, easier communication, and a better chance the guide can check in with everyone.

The meeting point is at Blue Coast Tours Sesimbra, right by Rua Clube Naval de Sesimbra at Porto de Abrigo. It’s described as near public transportation, and you get a mobile ticket, which is a nice low-friction setup when you’re moving around town.

In plain terms: this is a “do it now” coastal trip. You show up, follow the crew’s instructions, and spend your time on the water where the views and snorkeling are the point—rather than spending your morning on logistics.

The route: Ribeira do Cavalo, Praia da Mijona, Inferno, Baleeira

The best way to think about this trip is that each stop offers a different flavor of coastline. You’re not staying anywhere long, so you’ll want to be ready to enjoy what each place does well.

Stop 1: Ribeira do Cavalo Beach (about 30 minutes)

This is your first proper swim-and-snorkel moment. You get 30 minutes with the admission ticket included, plus you’re invited to get into the clear water and explore what’s below the surface using the snorkeling gear provided. This first stop is usually where you want to feel settled—water time plus a quick reset after boarding.

What to watch for: this is also the stop where water temperature can make or break the experience. One person noted the water was too cold for comfortable snorkeling in early September. If you’re heat-sensitive, treat Stop 1 as a try-first moment and be ready to switch to sightseeing if needed.

Stop 2: Praia da Mijona (about 30 minutes)

Next comes Praia da Mijona, another quieter beach stop with 30 minutes. Here, the admission ticket is listed as free. The focus is on enjoying the calm, clear water with a refreshing swim.

Because this stop is shorter, it’s best used for a quick loop: get in, check out the water, and then spend a few minutes taking in the view from shore before the boat moves on.

Stop 3: Inferno Beach (about 30 minutes)

Then you reach Inferno beach for another 30 minutes. The tour description frames it as a place for snorkeling and exploring the beach, while the admission ticket is listed as free.

This is the sort of stop that works best when you go in with curiosity and low expectations for long beach time. You’ll likely come away remembering the feeling of remote coastline more than the exact details of one underwater spot—and that’s not a bad trade for a short boat day.

Stop 4: Baleeira Beach (about 1 hour)

Your last and longest stop is Praia da Baleeira with 1 hour. This is where you get another chance to swim and explore the seabed with snorkeling gear. The tour also includes an offer of regional drinks for tasting on site.

This stop is the one I’d treat as your “finish strong” moment. If the water felt cold earlier, you may want to use this extended time to decide whether you want to snorkel again or shift into pure beach time. If you felt great earlier, you’ll appreciate the extra hour to slow down.

Snorkeling gear, timing, and the cold-water reality

Snorkeling is one of the main reasons to book this tour, and it’s built into the value. You get a snorkeling kit and a safe (life jacket) included. That means you don’t have to shop or rent gear before you go, and the crew can point you in the right direction once you’re near the water.

The time blocks are short—mostly 30 minutes per stop, then 1 hour at Baleeira. That timing is good for most people because it keeps things focused, but it also means you shouldn’t treat snorkeling here like an all-day activity. Think of it as: try it, enjoy it, and take what you can get in the time available.

The one real-world factor that can change everything is water temperature. In early September, someone mentioned the water was too cold to snorkel comfortably, and the practical fix was renting a wet suit if they did it again. That lines up with what I’d tell you to consider: if you’re not comfortable in cool water, plan a wet suit option rather than assuming you’ll be fine.

Also, do yourself a favor and come prepared for sun. A review specifically flagged wearing sunscreen, and on a boat and on open beaches, that’s solid advice.

Coastline views you can’t get from shore

Where this trip really earns its keep is the movement. You’re not stuck taking photos from one beach. The boat ride gives you coastal views of hidden beaches and caves along the coast, and the route is paced so you can enjoy the shoreline as you travel between stops.

That matters because Sesimbra’s coastline isn’t just pretty—it’s dramatic. You’ll see why people like this area for boat days: rocky edges, small inlets, and that sense of space where the coast feels wild even when you’re close to town.

One practical tip: keep your eyes up during the transfer time. The best photo angles often happen while you’re still moving. Once you’re dropped onto a beach, your attention narrows to the water and the sand, so take in the broader view before you commit to snorkeling.

Price and value: what $59.91 buys you (and what it doesn’t)

At $59.91 per person, this is priced like an organized half-day coastal activity. The value comes from the inclusions, not just the boat ride. You’re getting all fees and taxes, a guide, a snorkeling kit, a safe, and a regional drink.

To judge value fairly, ask what you’d otherwise pay for:

• Gear rental or buying your own snorkeling setup
• A guided trip so you don’t lose time figuring out where to go
• A planned route that stacks multiple beach experiences into one outing
• At least one included drink, which turns the end of the trip into more than just logistics

What’s not included is also clear: snacks and soda/pop. If you know you get hungry quickly, bring a plan for food. The tour includes water time and beach time, but it’s not described as a lunch-style outing.

From the experience side, one review mentioned a little wine at the end, which matches the idea of a regional drink included. Even if you don’t drink wine, it’s still a nice extra that makes the return trip feel like part of the experience rather than a hard cutoff.

Marco and Jorge: how the crew changes the vibe

A guide can make a boat trip either smooth or chaotic, especially when you have multiple short stops. Here, the guidance is a big part of the appeal.

People specifically praised Marco and Jorge for being friendly and for having good English, with solid explanations along the way. That matters because snorkeling gear use and safety need clarity, and you also want to understand what you’re looking at when you’re staring at a coastline full of inlets and small coves.

One more small but useful detail: one review noted that maps led exactly to the right spot, but the location wasn’t clearly labeled in person. So when you arrive, don’t assume the meeting point will look obvious at a glance. Give yourself a few extra minutes to orient, and use the directions you have to find the right dock area.

Practical tips to make the 2.5 hours feel easy

This trip runs on tight timing, so preparation pays off. Here are the practical moves I’d make before you show up:

• Bring sunscreen. It’s an open-water day with beach time, and one review called this out directly.
• Think about a wet suit if you run cold. If early-season water feels frigid to you, that’s the difference between enjoying snorkeling and just watching the coast.
• Plan for snacks if you need them. Snacks and soda/pop are not included, so have a backup if you tend to get hungry.
• Arrive with a little buffer. The meeting location isn’t always easy to spot from a distance, so give yourself time to find the dock and settle in.
• Wear gear you’ll be fine getting wet in. The point is short beach swims, so comfortable swim-ready clothing beats trying to keep things pristine.

Also, if you’re booking around the weather: the experience requires good weather. That’s not a flaw in the tour—it’s just the nature of a small-boat plan along exposed coastline.

Who this trip is best for (and who should skip it)

This boat trip is a strong match if you want a balanced day: a mix of coastal views, short beach time, and snorkeling without spending hours driving or searching for spots.

It’s especially good if you like structure. You get timed stops, snorkeling gear included, and a guide who keeps the experience moving.

It’s less ideal if your goal is long snorkel sessions or lots of shore time. The stops are short, and the experience is designed to sample several beaches instead of lingering at one.

And if you’re very sensitive to cold water, treat snorkeling as optional. The trip still works as a scenic boat day, but snorkeling comfort can vary.

Should you book this secret bays snorkeling boat trip?

I’d book it if you want the Sesimbra coast in a short window and you like the idea of hitting several beaches without planning. The value is strong because the tour includes snorkeling kit, a safe, a guide, and even a regional drink, all wrapped into a small-group 2.5-hour outing.

I’d hesitate only if you know you won’t enjoy cool water and you can’t access a wet suit option. In that case, you may end up spending more time on shore than in the water.

If the weather is poor, the trip can be adjusted or refunded, so it’s also a pretty low-risk way to try the coast when conditions cooperate.
