Rio da Prata, Bonito MS: the longest snorkel float in the region
The Rio da Prata is the longest and most cinematic float in the Bonito region of Brazil. It starts with a forest trail, enters a spring-fed river and ends in a wide stretch where the shoals are biggest. This is the one to pick if you want a whole morning in the water.
What the Rio da Prata is
The Rio da Prata lies in the municipality of Jardim, next door to Bonito, in the state of Mato Grosso do Sul. Its water is filtered through the limestone of the Serra da Bodoquena and reaches the riverbed with almost no sediment in suspension. That is why you can see the bottom, the submerged trunks and the fish several metres away.
What sets it apart from the other floats in the area is length. Most snorkel floats around Bonito cover a few hundred metres; here the stretch in the water is considerably longer and changes character along the way, starting narrow with the forest almost closing overhead and finishing wide, near the junction with the Rio Formoso, where the fish are larger.
How the visit works, start to finish
The day begins at the reception of the farm with a briefing and equipment: a wetsuit, a buoyancy vest, a mask and a snorkel. Then comes a walk along a forest trail to the entry point. The trail is not just transport — it is where the guide shows the riparian vegetation and explains why it is the reason the river is clear.
From the entry point onwards the whole route goes with the current, the group in single file behind the guide. In the final stretch the river widens and deepens, and that is where the biggest shoals appear. You leave the water by a ladder and a vehicle takes the group back to the farmhouse.
You do not need to know how to swim. The vest keeps you at the surface and the current does the moving; your job is to look down and keep your feet off the riverbed, which is exactly what stirs up sediment and ruins the visibility for everyone behind you.
Rio da Prata or Rio Sucuri: which to choose
This is the most common question for anyone planning a trip to Bonito, and the answer depends on what you want from the morning.
| Rio da Prata | Rio Sucuri | |
|---|---|---|
| Time in the water | Long, with changing scenery | Short and concentrated |
| Getting to the river | Forest trail before entering | Short access, almost no walking |
| Fish | Bigger shoals in the final stretch | Fish very close throughout |
| Effort | You walk before and after | Very low, good with small children |
| Overall feel | An outing, with forest and river | A contemplative aquarium |
If you only have one day and want the fuller experience, most people pick the Rio da Prata. If you are travelling with small children, with someone with reduced mobility, or with little time between activities, the Sucuri tends to work better.
When to go
Water clarity here depends on rain, not on the calendar. On dry days visibility is at its best; after heavy rain in the headwaters the river can cloud over and the operation may be suspended until it settles. The driest months, May to September, are the most predictable — and also the ones when the water is coldest and the wetsuit matters most.
Between December and March it rains more and the risk of a cloudy day rises, although the forest is greener and the heat makes getting into the water more pleasant. If your trip falls in that window, book the float for the first days of your stay: that leaves room to rebook if the river closes.
What to bring
- Footwear that can get wet and muddy on the trail: neoprene booties, sturdy sandals or old trainers.
- Swimwear worn underneath — changing on site is quick and not always comfortable.
- A towel and a dry change of clothes for afterwards.
- A waterproof camera or a sealed phone case, on a lanyard.
- Insect repellent and sunscreen applied BEFORE you arrive, never at the riverbank: the product ends up in the water.
- Prescription glasses, if you depend on them — some operators have corrective masks, but this varies and must be arranged when booking.
Frequently asked questions
Do I need to know how to swim?
No. The vest floats you and the route goes with the current. People who are nervous in water usually settle within the first few metres, and the guide stays with the group throughout.
Can I go with children?
Yes, subject to the operator minimum age. The thing to watch is not the water but the trail and the duration: very young children tire before the end. In that case the shorter Rio Sucuri usually works better.
What if the river is cloudy on the day?
It happens, especially after heavy rain. The operator may suspend the float — a quality decision rather than a safety one. That is why it pays to book the float early in your trip and leave a spare day in the itinerary.
