This is the house reef for Habitat Curacao, and is very good. As mentioned, the rope from the dock goes out to the edge of the reef and then down to about 85' where the rope stops. Don't forget the shallows where there are numerous octopi, a mantus shrimp, sharptail eels, etc. Huge green morays to the east of the line at about 40' depth. And there is a frog fish at 45' west of the line on a rocky outcropping with about 4 sponges on it. HARD to find unless someone is good enough to show you. The reef gives out about 130' depth, and then the bottom continues to go down fairly steeply. I got to 170' without much trouble, and it would have been easy to continue deeper. Dive shop was very excellent. We loved diving from here. Honest air fills. BE WARY OF THE CURRENT! The current can change from nonexistent to undivable within an hour. Ask people coming in, but since conditions can change so quickly I recommend diving it with the thought that it's o.k. to abort!
