|Elphinstone is 6.5 nautical miles from the shore. You reach it by boat, either a liveaboard or on a day trip from Marsa Alam. It is better to do it from a liveaboard because you get longer on it, and the dive guides generally let you go deeper. It is 300 m long with sheer sides, and runs from North to South. At the middle it is just 1 m deep, but the walls drop steeply down to the depths. The current here can be very strong, which is good as it means plenty of fish life. Visibility is usually around 20 m.
