First suggestion is to get the local dive briefing book. It's very helpful to locate and navigate dive sites.
To find wreck alley first find the 3 or 4 balls at blue chromed reef. That the easy part. Wreck alley mooring ball is approx 100 meters south and a little further offshore all by itself.
Good luck.
