Gorée aquarium is a shallow Dakar-area dive with rocky patches and sand, built more for buoyancy practice than for big depth. It works well for training, snorkelling and night dives, with a simple profile that stays easy to read even when the sea has a little swell. Plan it as a relaxed shore session with a local operator, especially if you want the easy daytime route or the better night-life angle. Expect Senegalese reef fish, stingrays, boxfish, moray eels and crabs rather than big coral drama.
