This dive site gets its name from an old storm drain pipe that runs straight out to sea from shore. Adjacent to Horseshoe Reef, it is a great example of South Oahu reef structure. Bright hard corals grow along the pipe itself, as well as the reef surrounding it. Keep an eye out for frogfish! They like to use the corals on the pipe to camouflage themselves. If your air lasts, the reef at the end of the pipe is pristine! Look for large white mouth morey eels and octopus!
