Keawalo Pipe

Enter at the stairs leading into the sea over the sea wall next to the marine laboratory. It's an easy entry if the surf isn't breaking here. Bring a flag, as the reef is just a few feet deep here, and you'll be swimming parallel to the boat channel and just outside the channel markers. We dropped about half way between the inner and outer buoys, and this put us in 20 feet of water. Swimming out perpendicular from shore, there's a fair bit of reef, which is mostly dead. But there are lots of fish, turtles, eels, frogfish and scorpionfish, plus a whole lot of collector urchins (the kind with the friendly, short spines). Then we headed Ewa (towards the west) until we intersected the Kewalo Pipe. The pipe is an old defunct concrete storm drain, which provides a hard substrate for coral reef and associated life. We did a 90-minute dive and only made it to about 50 feet, so we didn't quite see the end of the pipe. Still, a great dive, despite moderate surface swells.
