エルフィンストーン・リーフ(Sha'ab Abu Hamra)はマルサアラムのダイビングを象徴する存在であり、紅海でもっともよく知られたリーフのひとつです。長さ約300m、幅わずか30mの細長い孤立した根で、南北方向に伸び、マルサアラムの町から北へ30km、海岸から12kmの外洋にあります。根のトップは水深5〜8m。そこから両側が垂直の壁として70mを超えて落ち、南端は水深55〜80mの有名なアーチへと崩れ落ちます。これはテクニカルの深度であり、レクリエーションの日帰りツアーでは潜りません。透明度は通常25〜40mとこの海岸でも屈指で、リーフが青の中に単独で立っているため大型生物が集まります。晩秋のヨゴレ、夏のアカシュモクザメ、通年のオグロメジロザメとツマジロ、さらにマグロ、バラクーダ、マダラトビエイ、そして春には時折リーフマンタも。1日はスピードボートでの3〜5時間の速いツアーです。ホテルお迎え、しっかりしたブリーフィング、外洋を約45分、ガイド付きダイビング2本とその間の水とスナックの水面休息、そして昼食までにはホテルへ戻ります。エルフィンストーンが見返りに求めるのは技量です。流れは両方のプラトー沿いに強く走ることがあり、プロファイルは深く、何かあっても流れ着ける浅いリーフはありません。
If there were a way to give 10 stars, Elphinstone Reef would deserve every single one of them!
Every time we visit Elphinstone, it delivers something spectacular. The reef is absolutely breathtaking, packed with vibrant marine life, stunning coral formations, and endless underwater action. No two dives are ever the same, which is exactly why we keep coming back.
Our most unforgettable experience was in December when we had an incredible close encounter with a Longimanus (oceanic whitetip shark). Seeing such a magnificent animal from so close was both thrilling and humbling. It was one of those moments that reminds you why you fell in love with diving in the first place.
Elphinstone seems to have a magical rule: if you arrive expecting something amazing, it will exceed your expectations anyway! From curious reef inhabitants to big pelagic surprises, this place never disappoints.
For divers, Elphinstone isn’t just a dive site, it’s an addiction. The only downside is that every reef you visit afterward has a very hard act to follow!
Can’t wait to come back and see what surprises Elphinstone has waiting for us next. 🦈🌊🤿

One of the most thrilling dives I’ve ever done. Elphinstone Reef offers stunning drop-offs, vibrant soft corals, and a real chance to see oceanic whitetip and hammerhead sharks. Currents can be strong, so it’s best for experienced divers. I joined a liveaboard to beat the crowds and catch early morning dives—totally worth it. Visibility was fantastic, and every dive felt like an adventure. A must-do Red Sea site if you're into big fish and deep wall diving.

Very nice location to go diving. When we were here, there was a lot of things we got to see. It of course depends on different factors what you actually see, but it is definitely worth to do a couple of dives here.

Best dive site with sharks in the red sea
I dont recommend going with a speed boat from shore if wind is more than 18 knots - its usually 18 knots
Sharks are amazing and you get to sea oceanic white tip sharks - long manous - and hammer head sharks along with tiger sharks
If you are not an experienced diver then its not recommended
