From the 100's of times I dived on Ras Um Sid, my favourite place of all, only seldom I could cross to the other side, where this shallower garden is.
The way was rather tricky, mostly because of the huge currents, and the depths we had to cross to arrive there. Not enough air and/or big decompressions...
Nowadays, there is a beach and surelly acess there, but not then.
