The swim stop, explained
Lagoa Azul and the bay stops: what the snorkelling is actually like
Shallow, clear, sheltered water over rock and reef — what to expect from the day's one real swim stop, and how the other three bay stops differ from it.

| Stop | In the water? | What it's for |
|---|---|---|
| Ilha de Cataguás | No | Scenery — a slow pass or brief anchor |
| Lagoa Azul | Yes — the main stop | Snorkelling, shallow and sheltered |
| Freguesia de Santana | No | A short walk to the 1843 church |
| Praia do Japariz | Often, around lunch | Buffet lunch, some swimming time |
What Lagoa Azul actually is
Lagoa Azul — the Blue Lagoon — isn't a landlocked lagoon in the postcard sense but a sheltered stretch of the bay, shallow and clear over rock and reef, calm enough on most days that the schooner can anchor close in and let passengers get straight into the water. It's the stop this itinerary is built around: the other four stops are brief calls, but Lagoa Azul is where the schedule actually slows down and lets people swim rather than just look.
What you see under the mask
Visibility depends on the day — recent rain upriver or a stirred-up sea both cloud a lagoon like this — but on a clear day expect small reef fish moving over rock and coral rubble in a few metres of water, well within reach of a snorkeller without diving gear. This isn't the Caribbean's open-water reef diving; it's shallow, sheltered snorkelling suited to first-timers and children old enough to wear a mask confidently. Life vests are generally available for anyone who wants the reassurance, which makes it accessible to weaker swimmers as well.
The other three stops, briefly
Ilha de Cataguás and the other small islets the schooner passes are scenery rather than swim stops — a slow pass or a brief anchor rather than time in the water. Freguesia de Santana is a land stop: a short walk to the 1843 church rather than a beach call. Praia do Japariz, the lunch stop, usually allows some swimming time around the meal, so pack for the water there too rather than assuming Lagoa Azul is the only chance to get wet.
Getting the most out of the swim stop
Time in the water at Lagoa Azul is finite and shared across a full boatload, so being ready — mask already on, not still digging through a bag — buys real minutes. A rash vest solves two problems at once on a stop this exposed to the midday sun: sunburn on a floating snorkeller's back and shoulders, and one less layer of sunscreen washing into the lagoon. If you get seasick on the crossing between stops, this is the stop to shake it off in — nothing settles a queasy stomach like getting off the boat.
Who this stop suits, and who it doesn't
Confident swimmers and snorkellers get the most from Lagoa Azul, but the shallow, calm water and the available life vests make it workable for nervous swimmers and reasonably confident children too. It suits anyone who wants to see fish without a scuba certification. It's a poor fit if you specifically want deep-water diving or a long, uninterrupted swim — the schedule moves the group on to the next stop, and Lagoa Azul is a highlight of the day rather than the whole of it.
Gear: bring your own, or use what's aboard
A mask and snorkel you already know fit properly are worth packing from home, particularly for anyone who has struggled with a leaking mask before — a stop this short is the wrong time to be fighting rental equipment. That said, gear is generally available to rent or borrow on board for anyone travelling light, and the crew are used to fitting first-timers who have never snorkelled before. Fins are optional in water this shallow and calm; most people manage fine without them, and one less thing to carry through a day with several boat transfers is its own small mercy.
Weather, tides and why stops can change
Because the schooner is at the mercy of the same conditions as every other boat on the bay, a rough morning or an unusually low tide can see the guide substitute one stop for another, or shorten time in the water at Lagoa Azul specifically. This isn't unique to this operator — it's true of every small-boat excursion on this coast — and it's worth arriving with the expectation that the itinerary is a plan rather than a contract. On most days, in the Southern Hemisphere's warmer months especially, conditions are calm enough that the full stop list runs as advertised.
