Grand River South East Waterfall

GRSE Waterfall, or Grand River South East Waterfall, is a scenic cascade on Mauritius’ southeast coast usually reached by boat. It suits families, couples and first-time visitors, especially on an Île aux Cerfs trip; expect a relatively short waterfall stop rather than a hiking experience.

Grand River South East Waterfall, usually shortened to GRSE Waterfall, is one of the most recognisable natural stops on boat trips along the southeast coast of Mauritius.

The attraction is not simply the cascade itself. Much of the experience comes from travelling from the open lagoon into the Grand River South East, where the waterway narrows between dark volcanic rock, dense vegetation and green riverbanks before the waterfall appears ahead.

Most visitors experience GRSE by boat. Tours operating around the east and southeast coast frequently include the waterfall alongside Île aux Cerfs, making it an easy addition to a full lagoon excursion rather than a destination that requires a separate day.

As the boat approaches the falls, the surroundings feel very different from the open coast. The river becomes more enclosed, the vegetation thickens and the dark rock around the cascade creates a strong contrast with the falling water.

The waterfall’s appearance changes naturally with rainfall. After wetter periods there may be a stronger flow, while during drier conditions the cascade can be less powerful. That variation is part of visiting a natural waterfall rather than a controlled attraction.

Wildlife can sometimes be seen around the riverbanks, including birds and monkeys, but sightings should be considered a bonus rather than an expected part of the visit.

GRSE works particularly well for families, couples, photographers and travellers already planning an east-coast boat trip. It is also a good choice for visitors who want to see a waterfall without committing to a long forest hike.

It may be less rewarding for travellers specifically looking for a secluded waterfall trek, a long stop beside the cascade or an independent hiking experience. Boats often spend only a relatively short period near the falls before continuing their itinerary.

For a fuller east-coast day, combine GRSE Waterfall with Île aux Cerfs, Trou d’Eau Douce and the surrounding lagoon.

Visitor Facts

GRSE Waterfall is located at Grand River South East on the southeast coast of Mauritius. The most common visitor experience is by boat through the river, and many Île aux Cerfs speedboat and catamaran excursions include a waterfall stop. The visit itself is generally only one section of a longer boat itinerary, and the exact approach depends on river, weather and operational conditions.
