1. Coral Beach Nature Reserve — South shore, toward the Egyptian border
The world's northernmost coral reef, reachable by swimming a few metres off the sand.
Coral Beach Nature Reserve protects the northernmost coral reef in the world, and it is close enough to shore that snorkelling from the beach puts you over living coral within a couple of minutes.
The reserve maintains marked snorkelling routes and bridges over the reef top so swimmers cross without standing on it, which is why the coral here is in far better condition than on the unprotected stretches nearby. The fish life is genuinely impressive.
There is an entry fee, equipment hire on site, and facilities. Mornings have noticeably better visibility before the afternoon wind gets up.
Good to know: Go in the morning — the wind picks up in the afternoon and visibility drops with it.
