We did a twilight dive entering at Andrea II, going along the reef to Andrea I, then returning at a shallower depth back to Andrea II. Most interesting part of the dive was at safety stop depth, after all the film in the camera had been shot, a 'squid squadron' came along with us for a bit. There is a locked barricade at the boat ramp walls here, but we parked by it and had just a short hike to the entry. You definitely want to pre-scout your entry point before donning your gear here.
