Most dives on Um Gammar takes place on the south east corner. This partly because the moorings there work when the wind comes from the north, like it normally does, plus many guests want to dive the cave there. This means that the north end is rarely dived even if it’s a beautiful site.
If you’re lucky enough to have a Zodiac at hand this dive is easily approached. If you dive from a daily boat without Zodiac you might have to make a standby drift from the main vessel. With wind from the north east the boat can moor up in a small bend in the reef but most of the time this is not possible. Either way you will enter the water just north of the reef and descend to the north plateau. The edge of the drop-off is at a depth of around 30 meters so keep an eye on your SPG and NDL time as you swim south.
At the south end of the plateau you will find a few small coral blocks and then the shelf gives way to a sheer wall for a few minutes. Keep an eye out for large predatory fish, sometimes you can see grey reef sharks or even hammerheads here. Below you will soon see a narrow shelf on 35 meters and the wall turning into a steep slope. Now you have the bend in the reef with the moring coming up ahead, time for safety stop.
