Long Canyon
Canyons cut into a reef table at only 8-10 m

Long Canyon is a wide reef table cut by a system of canyons at 8 to 10 m, dived for the canyons themselves rather than for anything out in the blue. It is a popular site on this coast, and the shallow depth means the exploration of its twists and turns is limited by patience and gas rather than by no-decompression time.
Where it is and how deep
25.3473° N, 34.7768° EApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
The site is a big, wide reef table with many canyons cut inside it, all in relatively shallow water of 8 to 10 m. That depth is the point: with the whole dive in the top 10 m, gas lasts, no-decompression time is not a factor, and you can spend the time following the canyon system instead of watching a computer. The dive is spent inside the reef table rather than along its outer face, so expect to lose sight of open water for stretches at a time.
Inside, the canyon offers a long run of twists and turns to explore, and sun beams come down through the sockets in the coral reef overhead. Take it slowly. Working a canyon system cleanly is a matter of fin technique, and a diver kicking hard will silt or scrape what is easy to pass at a crawl. Work the system in one direction, keep the diver behind you in sight at the turns, and come out over the top of the reef table for the ascent.
