As I roll backwards off the dive boat and deflate my buoyancy jacket, my field of vision changes from sky to sea. It's a glorious feeling, that first dive of any trip, as you descend into clear blue water and the outlines of a coral reef start to materialise below you.
Here are the bright blue fingers of Acropora, the green mounds of Porites, and the convoluted contours of brain coral. Bushy gorgonians and sea whips wave back and forth in the currents. Fusiliers hover in shoals just off the reef, and butterfly fish flit between the corals.
This arena is Jackson Reef, which lies alongside Tiran Island at the entrance to the Gulf of Aqaba. It offers some of the finest diving in the northern Red Sea. As I descend further, a turtle passes me on its way up for some air. Thankfully, I have at least an hour before I have to do the same: ample time to enjoy the profusion of hard and soft corals that thrive in this amazing environment. Schools of barracuda and jacks hang out in the open water, and I even spot a juvenile shark cruising around in the blue.
Britain's nearest accessible coral reefs lie in the Red Sea. The main gateway to the region is the Egyptian resort of Sharm El Sheikh, back to normal after last July's bombings. When I first dived these fabled reefs nearly 20 years ago, Sharm's Naama Bay boasted one hotel, a petrol station, one dive shop, and a bar. Today it has 141 hotels, 164 dive centres, and more than 300 dive boats.
Because of Sharm's spectacular growth there is a twice-daily scrum at the two public jetties while divers board in the morning and disembark in the evening. But you can avoid this at the Four Seasons resort: the hotel has special permission to operate dive boats from its own jetty. In addition, the resort's dive centre is equipped with an extremely powerful Zodiac which makes the trip out to Tiran in a record-breaking 15 minutes. On an early morning dive, you can beat the crowds and be back in time for breakfast.
These facilities make a huge difference to the experience of diving these legendary sites. On top of this, it really is deluxe service: you don't have to lift a finger (or a scuba tank) if you don't want to, all your kit is taken care of, and a dry towel or a cold drink is offered as a matter of course the minute you step out of the water. Five-star diving indeed.
Unfortunately, everybody still has to put up with the overcrowded conditions at Sharm El Sheikh airport - at least until a new terminal opens in 2007. But that is relatively easy to forget once you're speeding out to your chosen site and ready to drop down into those blue waters.
