Key takeaways
- Palmar and Belle Mare, the shallow banks and the approach to Ile aux Cerfs.
- Everything above, plus the eastern underwater waterfall off Grand River South East. The one most people book.
- Further south again to Lion Mountain and the coastline beyond the river mouth.
- The aircraft flies with your party and the pilot, whichever length you take.
Three routes, not one route in three sizes
The easy assumption is that these are the same flight with the clock stopped at different points, and that a longer booking simply buys more of the same view. That is not quite what is happening. The aircraft leaves from the same stretch of water each time, but the three lengths turn back at three different places, and the things worth seeing on this coast are spread out along it.
So the choice is geographic rather than numeric. The question is not how long you want to be in the air. It is how far south you want to get.
The fifteen minute flight
The shortest option works the lagoon in front of the departure beach. That means the water off Palmar and Belle Mare, the sandbanks and channels that run through it, the coral flats, and the approach to Ile aux Cerfs before turning back.
It is easy to be dismissive about the short one and it does not deserve it. The lagoon here is the largest in Mauritius and the part directly off the departure beach is among the best of it. In fifteen minutes you get the water take-off, the climb, the colour bands, the island, and the landing, which is a complete experience rather than a truncated one.
What it does not do is reach the shelf edge off Grand River South East, and therefore it does not show you the underwater waterfall. If that is why you are booking, this is the wrong option, and it is the single most common mistake made on this flight.

The twenty minute flight
This is the operator's best seller and it is easy to see why. It covers everything the short flight covers and then continues south past Ile aux Cerfs to the shelf edge, where the eastern underwater waterfall appears.
The extra five minutes buys the thing that distinguishes this coast from any other beautiful lagoon. Sediment streaming off the edge of the shelf into deep water, drawn in falling lines by the channels cut into the slope, is not something you can see from a boat or a beach or a hotel balcony, and it is the reason a scenic flight here is different from a scenic flight over any warm shallow sea.
If you are choosing on value rather than on time, this is the one. It is the shortest flight that includes the headline sight.
The thirty minute flight
The longest option keeps going. Past the waterfall it continues down the coast towards Lion Mountain and the bay beyond, which changes the character of the flight: the first half is water and the second half brings in land, ridges, a river mouth and a mountain.
That contrast is the argument for it. A lagoon is astonishing for about ten minutes and then the eye adjusts, and having something structurally different in the second half of the flight keeps it interesting. It is also the only version that shows you how the east coast actually fits together, from the resort strip in the north to the wilder ground in the south.
The argument against is simple arithmetic: it is twice the fifteen minute flight for a stretch of coast that some people will find less remarkable than the lagoon they have just crossed. If your priority is the water rather than the island, the twenty minute flight is the efficient choice.
What private actually means here
All three are sold as private, and on an aircraft this size that word means something more concrete than it does on a coach tour. The aircraft goes up with your party in it. There is no other booking sharing the cabin, nobody else's schedule shaping the route, and no waiting for a minimum number of passengers before the flight runs.
It also means the cabin is small. This is a light floatplane, so the passenger capacity is very limited and the pilot is sitting next to you rather than behind a door. People consistently describe that as the thing that made it feel like flying rather than being flown, and it is worth knowing in advance if you were expecting something more like a helicopter tour.
One consequence of the small cabin is the weight limit, which is 105 kilograms per passenger and applies whichever length you book. It is a weight and balance figure rather than a policy, so it does not flex.
How to decide
Work backwards from the underwater waterfall. If you want it, you need twenty minutes or thirty. If you are indifferent to it and mainly want to be in a small aircraft over extraordinary water, fifteen is honest and complete.
After that, consider the weather. On a settled morning with high sun and a flat lagoon, the longer flight rewards you with a second act. On a day with cloud building over the interior, the extra ten minutes may be spent looking at grey ridges rather than green ones, and the lagoon portion is the reliable part.
Finally, consider how you handle small aircraft. If you are unsure, the short flight is a sensible way to find out, and nobody has ever regretted a fifteen minute flight over this lagoon.
