Aloha; We're heading here in a week. We've snorkeled pretty much everywhere but never along the north east side of Oahu. And we've stayed @Turtle Bay twice, so know all the spots from there west. The water looks amazing having driven along the highway many times in the past, but we've never checked it out. And it looks like there's a reef protecting a long stretch of the beaches around there, (viewed by satilite images). Mahalo!
