Mapped this site for my PADI Dive Master requirement. This is an EXCELLENT site for snorkelers, beginners and up. Plenty to see. Tons of different fish including eels and lionfish. I've also seen rays, sea cucumbers and a shark. Perfect dive for day or night. From the coral pillar near the end of the pipeline, take a heading of 270 degrees (due West) and, after about 20 minutes of easy diving, you get to the Amtrak. On your way back, take a heading about 20 degrees to your right. When you get to the coral, turn left and you'll pass by a beautiful wall of soft coral.
