Ponta D'Ouro in Mozambique is exquisite. I love going there, but during peak holiday season the natural peace is destroyed by quad bikers and jet ski's. The jet ski's especially should be banned. They are noisy and have no consideration for swimmers in the bay. I would imagine that they also would chase away dolphins and whale sharks. For me, it brings down the quality of the esperience of visiting there. I hope there is some intervention. Already, high-end tourism - which pays more and understands the value of pristine nature has moved elsewhere.
