Hi yes, it was a couple of years ago now but we spent about a month out there. Tips and advice, go, dont hesitate, just do it! Phenomenal diving, but hard work. Getting a licence was complicated, and I've heard it's got worse. There are few anchorages some less than ideal. If the conditions look good for Bolier stop what you've already planned and go, they wo t stay good for long.... if you plan to explore you need at least 450 ft chain and rode, did I mention that some anchorages are less than ideal? Everyone who doves needs to be very confident in the water, think currents strong enough to remove your mask and climbing into a dinghy in a six foot swell. Bit totally worth it.
