I was there on the 24th last year. The guys I tagged along with were on it the day before scouting safe penetration areas, and decided to enjoy the fruits of their prior days labors, and treat me to it. They dropped us at mooring ball 3 on the telescope turret, and we spent the whole dive inside running back and forth to stay out of the current.
The second dive the OP gave us the option to just move to another mooring ball, or do a drift dive, so we live dropped at mooring ball 1 and spent the first half of our dive inside, then cruised along the sides back and forth until we hit the last ball where the boat tied in.
Two great dives, but gnarly currents!
I was hoping to get back on her this October, but the weather didn't cooperate, and the dive op didn't go out on the days I was in KW. I was hoping to get a little outside time since I saw more INSIDE than anything else last year!
(and there are a LOT of nasty dark corridors to get lost in!)
I could spend a whole vacation just diving that and be happy though!
