This waterfall empties straight into the sea, and you can navigate almost under it in a boat (well get an experienced boatman, there are some tricky sections). You can take a trip from the harbour at GRSE (Grand River South East, but everybody calls it GRSE). While you are there, you can take a trip to Ile aux Cerfs, a lovely island with beautiful beaches, but also alas with lots of overpriced excursions, gift shops and restaurants.
New post title waterfall looks great!
